My 1992 Analog Devices databook lists this as 8-bit DAC with microprocessor interface. Depending on the accuracy you need, you could replace it with a circuit that contains a 74HCT374 for the register, and an R2R gate for a cheap D-A conversion. An OpAmp on the output could do basic filtering. It'll never reach the linearity of the original part, but it gets your circuit running again for about two bucks (I assume you need a spare part?). Also try the search option of www.kruse.de - they list more than 3900 units of this thing, enough for a mass production. www.beganto.com does not list them (although it calls itself "leading search engine" - they're working hard :-)). ciao, -- Jens Sch�nfeld -- Author: Jens =?iso-8859-1?Q?Sch�nfeld?
