±200V Common-Mode Voltage  
DIFFERENCE AMPLIFIER  
DESCRIPTION  
FEATURES  
HIGH COMMON-MODE VOLTAGE:  
+75V at VS = +5V  
The INA148 is a precision, low-power, unity-gain  
difference amplifier with a high common-mode input  
voltage range. It consists of a monolithic precision  
bipolar op amp with a thin-film resistor network.  
±200V at VS = ±15V  
FIXED DIFFERENTIAL GAIN = 1V/V  
LOW QUIESCENT CURRENT: 260µA  
WIDE SUPPLY RANGE:  
Single Supply: 2.7V to 36V  
Dual Supplies: ±1.35V to ±18V  
LOW GAIN ERROR: 0.075% max  
LOW NONLINEARITY: 0.002% max  
HIGH CMR: 86dB  
The on-chip resistors are laser trimmed for an accu-  
rate 1V/V differential gain and high common-mode  
rejection. Excellent temperature tracking of the resis-  
tor network maintains high gain accuracy and com-  
mon-mode rejection over temperature. The INA148  
will operate on single or dual supplies.  
The INA148 is available in a small SO-8 surface-  
mount package and it is specified for the –40°C to  
+85°C extended industrial temperature range.
