Digit, Low Power, High CMRR,

LCD/LED Display-Type A/D Converters

Description

The Intersil HI7131 and HI7133 are 3

1

/

2

digit, A/D convert-

ers that have been optimized for superior DC Common

Mode Rejection (CMRR) when used with a split

±5V

supply

or a single 9V battery. The HI7131 contains all the neces-

sary active components on a single IC to directly interface an

LCD (Liquid Crystal Display). The supply current is under

100µA and is ideally suited for battery operation. The HI7133

contains all the necessary active components on a single IC

to directly interface an LED (Light Emitting Diode).

The HI7131 and HI7133 feature high accuracy performance

like, 120dB of CMRR, auto-zero to less than 10µV of offset,

fast recovery from over load, zero drift of less than 1µV/

o

C,

input bias current of 10pA maximum, and rollover error of

less than one count. A true differential signal and reference

inputs are useful features in all systems, but gives the

designer an advantage when measuring load cells, strain

gauges and other bridge-type transducers.

The HI7131 and HI7133 are supplied in a 40 lead plastic DIP

and a 44 lead metric plastic quad flatpack package.

Features

• 120dB CMRR Equal to

±0.01

CAUTION: Stresses above those listed in “Absolute Maximum Ratings” may cause permanent damage to the device. This is a stress only rating and operation

of the device at these or any other conditions above those indicated in the operational sections of this specification is not implied.

NOTES:

1. Input voltages may exceed the supply voltages provided the input current is limited to

±100µA.

2. TEST pin is connected to internally generated digital ground through a 500Ω resistor (see text for TEST pin description).
