Programmable Gain

DIFFERENCE AMPLIFIER

FEATURES

DESCRIPTION

● DIFFERENTIAL GAIN = 1V/V TO 1000V/V:

The INA145 is a precision, unity-gain difference

amplifier consisting of a precision op amp and on-

chip precision resistor network. Two external resistors

set the gain from 1V/V to 1000V/V. The input com-

mon-mode voltage range extends beyond the positive

and negative rails.

Set with External Resistors

● LOW QUIESCENT CURRENT: 570µA

● WIDE SUPPLY RANGE:

Single Supply: 4.5V to 36V

Dual Supplies: ±2.25V to ±18V

On-chip precision resistors are laser-trimmed to achieve

accurate gain and high common-mode rejection. Ex-

cellent TCR tracking of these resistors assures contin-

ued high precision over temperature.

● HIGH COMMON-MODE VOLTAGE:

+8V at V_S= +5V

±28V at V_S= ±15V

● LOW GAIN ERROR: 0.01%

● HIGH CMR: 86dB

The INA145 is available in the SO-8 surface-mount

package specified for the extended industrial tempera-

ture range, –40°C to +85°C.
