High-Voltage, Programmable Gain

DIFFERENCE AMPLIFIER

FEATURES

DESCRIPTION

● HIGH COMMON-MODE VOLTAGE:

The INA146 is a precision difference amplifier that

can be used to accurately attenuate high differential

voltages and reject high common-mode voltages for

compatibility with common signal processing voltage

levels. High-voltage capability also affords inherent

input protection. The input common-mode range ex-

tends beyond both supply rails, making the INA146

well-suited for both single and dual supply applica-

tions.

+40V at V_S= +5V

±100V at V_S= ±15V

● DIFFERENTIAL GAIN = 0.1V/V TO 100V/V:

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.

● LOW GAIN ERROR: 0.025%

● HIGH CMR: 80dB

● SO-8 PACKAGE

A 10:1 difference amplifier provides 0.1V/V gain

when the output amplifier is used as a unity-gain

buffer. In this configuration, input voltages up to

±100V can be measured. Gains greater than 0.1V/V

can be set with an external resistor pair without affect-

ing the common-mode input range.

APPLICATIONS

● CURRENT SHUNT MEASUREMENTS

● SENSOR AMPLIFIER

● SYNCHRONOUS DEMODULATOR

The INA146 is available in the SO-8 surface-mount

package specified for the extended industrial tempera-

ture range, –40°C to +85°C.
