The DAC-8228's reference input can accept a negative voltage from 0V to .-10V (the DAC's internal unity-gain inverting amplifier inverts the input signal). Choose the DAC- 8229 for bipolar operation.

To make the DAC-8229 pin and functionally compatible with the DAC-8228, AGND A and AGND B should be tied together to function as V2, and Vss connected to GND. The DAC-8228 consists oftwo CMOS voltage output amplifiers, two high-accuracy R-2R resistor ladder networks, interface control logic, and two 8-bit registers. An internal regulator main- tains TTL logic compatibility and fast microprocessor interface timing over the full VDD range. The DAC-8228 dissipates only 90mW in the space saving 20- pin 0.3" DIP or the 20-Iead SO surface mount package. Its compact size, low power, and economical cost per channel, makes it attractive for
