DESCRIPTION
The DAC667 is a complete monolithic integrated cir-
cuit microprocessor-compatible 12-bit digital-to-ana-
log converter. 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 inter-
facing 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 lin-
earity 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.
