HI7131, HI7133

3 / Digit, Low Power, High CMRR,

LCD/LED Display-Type A/D Converters

August 1997

Features

Description

• 120dB CMRR Equal to ±0.01 Count/V of Common

The Intersil HI7131 and HI7133 are 3 / digit, A/D convert-

Mode Voltage Error

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).

• Fast Recovery from Input Overrange Results “Correct

First-Reading” After Overload

• Guaranteed 0000 Reading for 0V Input

• True Polarity at Zero for Precise Null Detection

• 1pA Input Current (Typ)

The HI7131 and HI7133 feature high accuracy performance

• True Differential Input and Reference

• Single or Dual Supply Operation Capability

• Direct LCD Display Drive - HI7131

• Direct LED Display Drive - HI7133

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

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

• Low Noise, 15µV

Without Hysteresis or Overrange

P-P

Hangover

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

and a 44 lead metric plastic quad ﬂatpack package.

• Low Power Dissipation, Guaranteed Less Than 1mW,

Results 8000 Hours (Typ) 9V Battery Life

• No Additional Active Components Required
