The DAC-8229 is a dual, 8-bit voltage-output multiplying CMOSD/A converter。 Its reference input accepts ± 2.5 V signal, which is inverted by an internal amplifier and passed to the output. VREFIt is also acceptable - 10 V, corresponding to a +10 V output (the maximum positive input signal supported is +2.5 V).
The DAC-8229 is designed for dual-supply operation; But put VSS, AGND A and AGND B are also supported with a single supply when connected to ground. At this point, its operating characteristics are similar to the DAC-8228 (its pinout allows it to support AD/PM-7528 and AD/PM-7628 sockets).
An internal regulator is available throughout the VDD TTL logic compatibility and fast microprocessor interface timing performance are available within range. In addition, each DAC input latch supports addressing, facilitating easy interfacing with microprocessors.
The DAC-8229 consumes less than 109 mW and is available in a 20-pin 0.3" DIP package or a 20-pin SO surface-mount package to save space. Its small size, low power consumption, and low cost per channel make them ideal for applications that use multiple D/A converters without sacrificing board space. The reduced number of components also contributes to system reliability.
PMI's advanced oxide isolation, silicon gate CMOS process, and highly stable PMI thin-film R-2R resistor ladder network enable the DAC-8229 to provide excellent DAC-to-DAC matching and temperature tracking capabilities.
The DAC-8229 is packaged in CERDIP or epoxy and has an extended industrial temperature range of -40°C to +85°C.
