Fast current switches and laser-trimmed thin-film resistors provide a highly accurate, fast D/A converter. Digital interfacing is facilitated by a double buffered latch. The input latch consists of one 8-bit byte and one 4-bit nibble to allow interfacing to 8-bit (right justified format) or 16-bit data buses. Input gating logic is designed so that the last nibble or byte to be loaded can be loaded simultaneously with the transfer of data to the D/A latch saving puter instructions. A reset control allows the DAC813 D/A latch to asynchronously reset the D/A output to bipolar zero, a feature useful for power-up reset, recalibration, or for system re-initialization upon system failure. The DAC813 is specified to ±1/2LSB maximum linearity error (J, A grades) and ±1/4LSB (K grade). It is packaged in 28-pin 0.3" wide plastic DIP and 28-lead plastic SOIC
