FEATURES  
The LT®1990 is a micropower precision difference ampli-  
fier with a very high common mode input voltage range. It  
has pin selectable gains of 1 or 10. The LT1990 operates  
over a ±250V common mode voltage range on a ±15V  
supply. The inputs are fault protected from common  
mode voltage transients up to ±350V and differential  
voltagesupto±500V.TheLT1990isideallysuitedforboth  
high side and low side current or voltage monitoring.  
Pin Selectable Gain of 1 or 10  
High Common Mode Voltage Range:  
85V Window (VS = 5V, 0V)  
±250V (VS = ±15V)  
Common Mode Rejection Ratio: 70dB Min  
Input Protection to ±350V  
Gain Error: 0.28% Max  
PSRR: 82dB Min  
High Input Impedance: 2MDifferential,  
On a single 5V supply, the LT1990 has an adjustable 85V  
input range, 70dB min CMRR and draws less than 120µA  
supply current. The rail-to-rail output maximizes the dy-  
namic range, especially important for single supplies as  
low as 2.7V.

8-Pin SO PackagUe  
The LT1990 is specified for single 3V, 5V and ±15V  
suppliesoverbothcommercialandindustrialtemperature  
ranges. The LT1990 is available in the 8-pin SO package.
