Dual 8-Bit, Voltage Output, Multiplying CMOS D/A

Product Details

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 VREF with 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 VDD range. 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.
