Description
The HI-X74(A) is a complete 12-bit, Analog-to-Digital
Converter, including a +10V reference clock, three-state out-
puts and a digital interface for microprocessor control. Succes-
sive approximation conversion is performed by two monolithic
dice housed in a 28 lead package. The bipolar analog die fea-
tures the Intersil Dielectric Isolation process, which provides
enhanced AC performance and freedom from latch-up.
Custom design of each IC (bipolar analog and CMOS digital)
has yielded improved performance over existing versions of
this converter. The voltage comparator features high PSRR
plus a high speed current-mode latch, and provides precise
decisions down to 0.1 LSB of input overdrive. More than 2X
reduction in noise has been achieved by using current
instead of voltage for transmission of all signals between the
analog and digital ICs. Also, the clock oscillator is current
controlled for excellent stability over temperature.
The HI-X74(A) offers standard unipolar and bipolar input
ranges, laser trimmed for specified linearity, gain and offset
accuracy. The low noise buried zener reference circuit is
trimmed for minimum temperature coefficient.
Power requirements are +5V and
±
12V to
±
15V, with typical
dissipation of 385mW (HI-574A/674A) and 390mW (HI-774) at
12V. All models are available in sidebrazed DIP PDIP and
CLCC. For additional HI-Rel screening including 160 hour burn-
in, specify “-8” suffix. For MIL-STD-883 compliant parts, request
HI-574A/883, HI-674A/883, and HI-774/883 data sheets.
