General part information

DAC8229 Series

The DAC-8229 is a dual 8-bit, voltage output, multiplying CMOS D/A converter. Its reference iput accepts a ±2.5 V signal, inverts and delivers it to the output with an internal amplifier. It can also accept −10 V at VREFwith a corresponding +10 V output ( the maximum positive input signal that it can accept is +2.5 V).The DAC-8229 was designed to operate with dual supplies; however, it can be operated with a single supply by connecting VSS, AGND A, and AGND B to ground. Its operating characteristics will then be similar to that of the DAC-8228 (whose pin-out allows it to drop into the AD/PM-7528 and AD/PM-7628 sockets).An internal regulator provides TTL logic compatibility and fast microprocessor interface timing over the full VDDrange. Also, each DAC input latch is addressable for easy microprocessor interfacing.The DAC-8229 dissipates less than 109 mW in the space-saving 20-pin 0.3" DIP or the 20-lead So surface-mount package. Its compact size, low power, and economical cost per channel, makes it attractive for applications requiring multiple D/A converters without sacrificing circuit-board space. Reduced parts count also improves system reliability.PMI's advanced oxide-isolated, silicon-gate CMOS process, coupled with PMI's highly-stable thin-film R-2R resistor ladder, offers superior matching and temperature tracking between DACs.The DAC-8229 offers cerdip or epoxy packaged devices in the extended industrial temperature range of −40°C to +85°C.
