Anyone have Datasheet of the PCM64??

Really no one have info of this there?

It is the 18bit parallel DAC...

There is the PCM63 which is part of that family but I couldn't find any info on the 64.
You can buy it at a few places, it has been used somewhere by Sony, there part number is 875997028.
Calling or mailing TI or Sony might bring a solution.

No datasheet, this is all i have:

18 bit, one channel.
parallel input, ttl, CSB/COB input type
THD+N -96dB
current ouput, unipolar -2.0mA, bipolar 1.0mA
powersupply +5 and -15V 415mW
42pin .6" DIP, plastic
gain error 0.5% max, drift 10 ppm/.C max
Vos drift unipolar 2.0 ppm/.C max, bipolar 2 ppm/.C max
Vos error bipolar 0.3%FSR
temp range 0-70.C

Hope this helps anyway,

Hi, Hatasa

As far as I can remember, the PCM64 was a low cost version of BB’s huge expensive industrial 18 bitter DAC729. No this one is not on TI’s web site either. It was one with trimpots for the last 2 LSB’s to trim it to 18 bits accuracy.

To find the PCM64P I think you have to dig through BB’s paper databooks from 8-10 years ago or so.

Hi Hatasa,

I have the databook (hardcopy), please mail me and I can have one pohotocopy for you.

cheers
