LINEAR TECHNOLOGY  LT1920CS8#PBF  仪器放大器, 1个放大器, 125 µV, 1.2 V/µs, 800 kHz, ± 2.3V 至 ± 18V, SOIC

The 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 ±2.3V to ±15V supplies. The high accuracy of 30ppm maximum nonlinearity and 0.3% max gain error G=10 is not degraded even for load resistors as low as 2k previous monolithic instrumentation amps used 10k for their nonlinearity specifications. The LT1920 is laser trimmed for very low input offset voltage 125mV maximum, drift 1mV/°C, high CMRR 75dB, G=1 and PSRR 80dB, G=1. Low input bias currents of 2nA maximum 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 LT1920 with two external 5k resistors passes the IEC 1000-4-2 level 4 specification.
