LT1167 - Precision Instrumentation Amplifier

General Description

The LT®1167 is a low power, precision instrumentation amplifier that requires only one external resistor to set gains of 1 to 10,000.

The low voltage noise of 7.5nV/√Hz (at 1kHz) is not compromised by low power dissipation (0.9mA typical for ± 2.3V to ±15V supplies).
