Anyone interested in a GB for AD1862? If so I can open a new thread at the Marketplace to discuss this.
I'm thinking about ordering some from DigiKey (Rochester Electronics), but it only comes in packages of 12 units and I only need 3-5 (2 for the stereo DAC + 1 to 3 to keep as spares), is anyone interested?
I'm not sure I can handle the purchase process, because I live in europe (inside the EU) and shipping + taxes are absurd, also the cost of 12 units is over my budget.

I haven't given up my AD1862's project, but since it seems not perdictable that I will get any of those chips soon, I'm thinking about first doing a project with the AD1851J if I'm able to get some.
To compare PCM5101A with PCM1794 - is like to compare Fiat Punto with BMW-5xx, but both are "cars" 🙂
OPA1656, OPA2156, OPA1612, AD8397.
Alex.
Yes, you are absolutely right, I apologize for that, it was a really unfortunate comparison. The PCM1794 competes in an entirely different league, being one of the best multibit sigma-delta DACs from TI. The fact that it features a differential current output also allows the designer to tailor the I/V stage to his/her preferences.
What about OPA627 and AD811 are they up to the task, or they are inferior?
All the Best,
Danny
AD811 is current feedback OP, so will not work not all schematics.
OP627 - was good OP.
It WAS good overpriced ancient OP for audiophiles
Now we have a lot much better and much cheaper.
And finished good TI's audio DACs...
Like AD1853 and 1955 finished AD.
Now ESS, AKM and Rohm does not leave AD and TI any chance.
But, if you for some reason want "NOS" and antient R2R, the best choise IMHO will be AD1862.

There are multiplying DACs which are true switched R 2R resistors accepting AC or DC +/- 10V inputs. A recent one and low cost is DAC8811. You can use the reference voltage as volume controls, or sign bit to get 17 bit resolution.
2x$20 for stereo is "low cost"? 🙂
I used it's dual version - DAC8812, got quite good results, but of course much inferior to 1862.
Where multiplying DACs are really useful - in analog volume tuning with the digital control. I used LTC1950, DAC8802, 8812 and 8814.

WM8742, PCM1792, DSD1792, PCM1794, DSD1794, PCM1796, DSD1796, PCM1798, AD1955, AK4399, AK4490, AK4493,AK4495,AK4497, AK4499, ES9018, ES9028, ES9038, ES9069...
P.S. This is not real "nonoversampling" (because of the nature of the SDM DACs), but internal oversampling digital filter can be bypassed for using the external one or not using at all.
Why is the AD1864 not popular, it is a fact that it has lower resolution, but is it that much inferior when compared with the AD1862?
As anyone tried this DAC?

I don't know, but Analog Devices lists them both as obsolete and no longer available. The AD1865 used to be the suggested replacement for the AD1864, so it appears that the AD1864 has been obsolete longer than the AD1865.
Yes now they are both obsolete. But like the AD1862 they are still available at Digi-Key and Rochester, I would like to know how they compare to each other regarding sound quality and reliability, specially in the highest grade versions. Does anyone knows?
Does anyone know if a Hifiberry DAC2 HD using PCM1796 can be set to bypass the internal digital filter? According to the PCM1796 data sheet:
"The external digital filter interface is selected by using the DFTH bit of control register 20, which functions to bypass the internal digital filter of the PCM1796."
