Just a quick heads up on new semiconductor development -- this time from TI.
A new process allows construction of native n-type as well as p-type devices on the same CMOS substrate. Previously, one has depended on "contortionism" to solve this problem. This means several things, both in terms of better analog chips and also for mixed mode devices.
In Q3 2002, TI will have completed their THS4271/4275 devices which are voltage feedback single op-amps. Specifications include high speed (1.4GHz, 970uV/s), low input voltage noise (2,8nV), fast settling (6.2nS to .1%), 90mA drive, low distortion (-90dBc at 30MHz which is low enough not to worry about but not radical)
AND most importantly support for 15V rails unlike some other fast/high performers from Analog Devices.
Looks nice. Now I am really wondering what they are going to do with this process and DAC chips ...
