DESCRIPTION
The ADC574A 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 micropro-
cessor 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 excellent sta-
bility 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 pro-
vide 8- or 12-bit resolution. The conversion time for 12
bits is factory set for 25
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 ADC574A, 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, and a hermetic side-brazed ceramic DIP.
