It includes a precision voltage reference, microcomputer interface logic, double-buffered latch, and a 12-bit D/A converter with a voltage output amplifier. Fast current switches and a laser-trimmed thin-film resistor network provide a highly accurate and fast D/A converter. A double-buffered latch facilitates microcomputer interfacing to 4-, 8-, 12-, or 16-bit data buses. The input buffer latch holds the 12-bit data until it is transferred to an internal 12-bit D/A converter latch, giving precise timing control over an analog output change. The DAC667 is specified to ±1/2LSB maximum linearity error at +25°C. The DAC667 is guaranteed monotonic over the specification temperature range. The DAC667 is available in 28-pin, 0.6" wide plastic DIP package. +VCC 8 Ref Out Ref In A3 A0 A1 A2 CS 6 7 12 15 14 13 11 28 Power Gnd 16 Reference –VEE 10 1 12-Bit D/A Converter 12-Bit Parallel Latch 5kΩ 2 5kΩ 3 9 5 4 10V Span Summing Junction VOUT AGND Bipolar Offset 20V Span 19.95k Ω 9.95kΩ 4 Bits...
