DESCRIPTION
The LT ®1168 is a micropower, precision instrumentation amplifier that requires only one external resistor to set gains of 1 to 10,000. The low voltage noise of 10nV/√Hz (at 1kHz) is not compromised by low power dissipation (350µA typical for ±15V supplies). The wide supply range of±2.3V to±18V allows the LT1168 to fit into a wide variety of industrial as well as battery-powered applications.
