LT1167AIS8#PBF

The LT1167AIS8#PBF is a low power precision Instrumentation Amplifier that requires only one external resistor to set gains of 1 to 10000. The low voltage noise of 7.5nV/?Hz (at 1kHz) is not compromised by low power dissipation (0.9mA typical for ±2.3 to ±15V supplies). The part's high accuracy (10ppm maximum nonlinearity, 0.08% max gain error (G=10)) is not degraded even for load resistors as low as 2k. The amplifier is laser trimmed for very low input offset voltage (40µV maximum), drift (0.3µV/°C), high CMRR (90dB, G=1) and PSRR (105dB, G=1). Low input bias currents of 350pA max are achieved with the use of superbeta processing. The output can handle capacitive loads up to 1000pF in any gain configuration while the inputs are ESD protected up to 13kV (human body). The LT1167 with two external 5k resistors passes the IEC 1000-4-2 level 4 specification.
