DIFFERENCE AMPLIFIER
FEATURES DESCRIPTION в—Џ DIFFERENTIAL GAIN = 1V/V TO 1000V/V:
Set with External Resistors
в—Џ LOW QUIESCENT CURRENT: 570ВµA The INA145 is a precision, unity-gain difference
amplifier consisting of a precision op amp and onchip precision resistor network. Two external resistors
set the gain from 1V/V to 1000V/V. The input common-mode voltage range extends beyond the positive
and negative rails. в—Џ WIDE SUPPLY RANGE:
Single Supply: 4.5V to 36V
Dual Supplies: В±2.25V to В±18V
в—Џ HIGH COMMON-MODE VOLTAGE:
+8V at VS = +5V
В±28V at VS = В±15V On-chip precision resistors are laser-trimmed to achieve
accurate gain and high common-mode rejection. Excellent TCR tracking of these resistors assures continued high precision over temperature. в—Џ LOW GAIN ERROR: 0.01%
в—Џ HIGH CMR: 86dB The INA145 is available in the SO-8 surface-mount
package specified for the extended industrial temperature range, –40°C to +85°C. ● SO-8 PACKAGE APPLICATIONS
