GENERAL DESCRIPTIONThe DAC-8228 is a dual 8-bit, voltage output, CMOS,D/A con-verter in a single chip.t was designed to dropinto AD7528/7628sockets eliminating two external op amps in applications suchas hard disk drives. These applications generally operate theAD7528/7628 with zero volts applied to Vand offset AGNDRerto +2.5 or +5 volts, The DAC-8228 is tested under both theseconditions.
The DAC-8228 can also be used in those applications requiringa unipolar output voltage, it can deliver an output voltage be-tween OV and +10V with Voo = +14V (maximum output voltageis Voo -4V). The DAC-8228's reference input can accept anegative voitage from 0V to -10V (the DAC's internal unity-gaininverting amplifier inverts the input signal). Choose the DAC8229 for bipolar operation.
