OPA1656: High-Performance CMOS Audio Op Amp

TI does. You can buy in almost any quantity directly from the TI Store on ti.com.

I did not know that. I thought they would not sell to private people just companies and in large quantity.
They are cheaper than Mouser though , but you need to order much to compensate for the double shipping costs. For an OPA 627 that's 6 $ a piece cheaper !
For an OPA828 , more than 3 $ cheaper ! :rolleyes: For an LME 49600 , more than 2 $.
That starts adding up !

But I have to use more recent browsers because add to cart doesn't always work and check out to see how to , does nothing for me. Mouser's website has no problem with my ancient browsers though .:) (but that's just me)

Hey johnc124 , have you any idea of how many they sell in the lifetime of an OpAmp like OPA627 or other popular and cheaper ones ? How much does T.I expect to sell of the OPA1656 ? 10 million ? 100 million ?
Luckily they ship them themselves , because at 0,9 $ a piece ... where is their profit on it ? Some of their inventory numbers seem very low in their site.
 
Well, considering I run TI's op amp business, you could say I'm very, very familiar with how many we sell over the lifespan of a part. Because of my role in the company and the nature of your question I can't give exact numbers, I can highlight some publicly available facts:

1. The lifespan of an op amp is long. Way longer than most other semiconductors. The OPA627 was released in the 90s and we're still selling them in high volume. I have other products of similar age that are still ramping up! I often describe making a new op amp like buying a stock. It might not make you rich tomorrow, but check in 20 years to see how it's doing.

2. You can see our earnings reports on TI.com, in the investor relations section. In 2020, TI reported almost USD$10.9B in revenue from analog, with an operating profit of $4.9B (from analog). That tells you 2 things: we sell A LOT of chips, and even at prices you may think are low, they have decent margins.

3. TI's R&D as a percentage of total revenue in 2020 is about 10.5%. We're pretty good at controlling the cost of the development process. So if we can develop a new op amp for less cost, and it will live in the market for decades, the risk of making a new part is fairly low.

Inventory levels on TI.com are extremely low at the moment, but that says less about the TI store than it does about the buying spree most of the market is on at the moment. For parts that are in high-demand, the inventory level on TI.com will mirror what it is at other distributors.

To the previous comment about TI setting up product distribution infrastructure being an interesting business decision: I don't think TI is alone or even first in this step. For example, I believe Microchip had an online store before us and many company's are also following suit. I don't think this is very different than many companies across multiple industries wanting to be able to sell directly to their consumers. With automation, the cost of these facilities is drastically reduced. I was laughing reading the comments about "humans putting chips in bags", all of that is definitely done by robots, at blinding speed, 24 hours a day, 365 days a year.
 
Seeing as how last I looked, you might just have a few competitors making similar parts, the profit margin is quite impressive!

As to distributors automated picking, the last I looked there still was a human bagging and labeling the picks. (Handwriting on the bags I think is still a give away!)

50 years ago when I worked at a local distributor, it was even then semi automated. But not quite enough. I spent a full day doing inventory of mil spec 1/2 watt 50 ppm resistors between 1,000 and 10,000 ohms! Even more surprising to me, was when one of the cute secretaries who was also working inventory came over and handed me a resistor she had found misplaced in her bins. She was doing the 25 ppm ones and found a 50 ppm one. Unusually knowledgable and observant!
 
The OPA627 was released in the 90s and we're still selling them in high volume.

Another surprize , you'd think considering the price and age , next gen OPA827-828 would have replaced the 627.

Even at prices you may think are low, they have decent margins.

Really ? On a new OPA1656 that cost around 0.9 $ , they have a decent margin ?
So much knowhow , production costs and it costs about the same as a bag of potato chips or one (cheap) beer . :eek:

Yes I've seen the graph : https://www.ti.com/about-ti/company/ti-at-a-glance.html
Is CMOS logic under Embedded or Other ?

I was laughing reading the comments about "humans putting chips in bags", all of that is definitely done by robots, at blinding speed, 24 hours a day, 365 days a year.

A lifetime ago I worked as an orderpicker for a supermarket chain , and I am out of touch and surprized again that this is done by robots for electronic components.
Easy enough with chips on reels , tubes may be more difficult . Not everything can be done with robots.
I am able to buy T.I CMOS logic IC's at prices far below T.I or Mouser , from a SEA distributer where I live ( no dodgy chinese ) ... but they use cheap human labour "to put them in a baggie" . ( like SN74LVC00APWR , 0.039 $ a piece , per 10 . T.I : 0.141 $ , Mouser 0.317 $ ... Cheap labour still wins ! :p)
I bought a bunch of them , not because I need them , but because they are so cheap.:rolleyes:

Op amps are not CMOS logic, they are ANALOG, even if they use CMOS technologies.

^ My question was CMOS logic like the 74HC series .
I know opamps are ANALOG .
The ADC/DAC's are analog and digital in one.
Still , in the graph , does logic sit in the "other" ?
"Other" is only 1/11th of "Analog" .

If it does not have an embedded externally programmed uC/uP or DLP, it is likely Analog.

ADC/DAC are Analog.

"The Company's Analog segment's product line includes High Volume Analog & Logic (HVAL), Power Management (Power), High-Performance Analog (HPA), and Silicon Valley Analog (SVA). HVAL products support applications, such as automotive safety devices, touchscreen controllers, low-voltage motor drivers, and integrated motor controllers."

New here. Hi. I’m a tubes and Opamp roller using inexpensive tube amps. I have been rolling a few different Opamps and just popped in a set of newly acquired OPA1656.

WOW! I’m glad I bought two sets so I can roll another pre-amp with these. The soundstage is immense, lows and highs and mids are just darn amazing.

Thank you TI and johnc124 and team!

7400 series logic is in our Interface Business Unit which is part of the "Analog Signal Chain (ASC)" portion of the company. My BU, Linear Amplifiers, is also part of ASC, along with motor drives, switching amplifiers, sensing products, data converters, and high speed data and clocking.
