Can somebody recommend ICs names or families for use as
programmable-gain high quality audio amplifiers? (as in high end
microphone or line amplifiers)
I am specifically looking for a very low noise op amp that can be gain
controlled from an external digital source, either in parallel form or
via I2C.
I am aware of the SSM2017/2019 device, which could be gain controlled
by the addition of external resistors and CMOS analogue gates. But I
would prefer an integrated solution..-(
I am also aware of the Crystal CS3310 (and the Wolfson equivalent) but
for various reasons, we cannot use these...-(
I am also aware of the "programmable resistors" manufactured by Xicor,
Analogue devices and Dallas. But it is not too clear from the spec
sheets what kind of noise of distortion these devices generate if used
in high end audio applications.
Has anybody used these for audio???
Or any other recommendations or suggestions anybody??
TIA
