DESCRIPTION
The ADC674A is a 12-bit successive approximation
analog-to-digital converter, utilizing state-of-the-art
CMOS and laser-trimmed bipolar die custom-designed
for freedom from latch-up and for optimum AC per-
formance. It is complete with a self-contained +10V
reference, internal clock, digital interface for micro-
processor control, and three-state outputs.
The reference circuit, containing a buried zener, is
laser-trimmed for minimum temperature coefficient.
The clock oscillator is current-controlled for excel-
lent stability over temperature. Full-scale and offset
errors may be externally trimmed to zero. Internal
scaling resistors are provided for the selection of
analog input signal ranges of 0V to +10V, 0V to
+20V,
±
5V, and
±
10V.
The converter may be externally programmed to
provide 8- or 12-bit resolution. The
conversion time
for 12 bits is factory set for 15
μ
s maximum.
Output data are available in a parallel format from
TTL-compatible three-state output buffers. Output data
are coded in straight binary for unipolar input signals
and bipolar offset binary for bipolar input signals.
The ADC674A, available in both industrial and
military temperature ranges, requires supply voltages
of +5V and
±
12V or
±
15V. It is packaged in a 28-pin
plastic DIP, or hermetic side-brazed ceramic DIP.
