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
100
μ
A 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 10
μ
V of offset,
fast recovery from over load, zero drift of less than 1
μ
V/
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.
