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

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.
