DESCRIPTION
The DAC667 is a complete monolithic integrated
circuit microprocessor-compatible 12-bit digital-to-
analog converter. It includes a precision voltage refer-
ence, 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 pre-
cise timing control over an analog output change.
The DAC667 is specified to ±1/4LSB maximum lin-
earity error (B and K grades) at +25°C and ±1/2LSB
maximum over the temperature range. All grades are
guaranteed monotonic over the specification tempera-
ture range. The DAC667 is available in two perform-
ance grades and in 28-pin, 0.6" wide plastic and
ceramic DP package types.
