LT1167 Single Resistor Gain Programmable, Precision Instrumentation Amplifier FEATURES DESCRIPTION n Single Gain Set Resistor: G = 1 to 10,000 The LT 1167 is a low power, precision instrumentation n Gain Error: G = 10, 0.08% Max amplifier that requires only one external resistor to set n Input Offset Voltage Drift: 0.3V/C Max gains of 1 to 10,000. The low voltage noise of 7.5nV/Hz n Meets IEC 1000-4-2 Level 4 ESD Tests with (at 1kHz) is not compromised by low power dissipation Two External 5k Resistors (0.9mA typical for 2.3V to 15V supplies). n Gain Nonlinearity: G = 10, 10ppm Max The parts high accuracy (10ppm maximum nonlinearity, n Input Offset Voltage: G = 10, 60V Max 0.08% max gain error (G = 10)) is not degraded even for n Input Bias Current: 350pA Max load resistors as low as 2k. The LT1167 is laser trimmed for n PSRR at G = 1: 105dB Min very low input offset voltage (40V max), drift (0.3V/C), n CMRR at G = 1: 90dB Min high CMRR (90dB, G = 1) and PSRR (105dB, G = 1). n Supply Current: 1.3mA Max Low input bias currents of 350pA max are achieved with n Wide Supply Range: 2.3V to 18V the use of superbeta processing. The output can handle n 1kHz Voltage Noise: 7.5nV/Hz capacitive loads up to 1000pF in any gain configuration n 0.1Hz to 10Hz Noise: 0.28V P-P while the inputs are ESD protected up to 13kV (human n Available in 8-Pin PDIP and SO Packages body). The LT1167 with two external 5k resistors passes the IEC 1000-4-2 level 4 specification.
