HI-774

Complete, 12-Bit A/D Converters

with Microprocessor Interface

August 1997

Features

Description

• Complete 12-Bit A/D Converter with Reference and Clock

• Full 8-Bit, 12-Bit or 16-Bit Microprocessor Bus Interface

• Bus Access Time . . . . . . . . . . . . . . . . . . . . . . . . . . 150ns

• No Missing Codes Over Temperature

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.

• Minimal Setup Time for Control Signals

• Fast Conversion Times

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.

- HI-574A (Max) . . . . . . . . . . . . . . . . . . . . . . . . . . . . 25µs

- HI-674A (Max) . . . . . . . . . . . . . . . . . . . . . . . . . . . . 15µs

- HI-774 (Max) . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 9µs

• Digital Error Correction (HI-774)

• Low Noise, via Current-Mode Signal

Transmission Between Chips

• Byte Enable/Short Cycle (A Input)

- Guaranteed Break-Before-Make Action, Eliminating

Bus Contention During Read Operation. Latched by

Start Convert Input (To Set the Conversion Length)

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.

• Supply Voltage . . . . . . . . . . . . . . . . . . . . . ±12V to ±15V

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.
