LT1167 - Single Resistor Gain Programmable, Precision ...

1 LT116711167fc TYPICAL APPLICATION FEATURES DESCRIPTIONS ingle Resistor Gain Programmable, Precision instrumentation AmplifierThe 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 Hz (at 1kHz) is not compromised by low power dissipation ( typical for to 15V supplies).The part s high accuracy (10ppm maximum nonlinearity, max gain error (G = 10)) is not degraded even for load resistors as low as 2k. The LT1167 is laser trimmed for very low input offset voltage (40 V max), drift ( V/ C), high CMRR (90dB, G = 1) and PSRR (105dB, G = 1).

2 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 LT1167 , offered in 8-pin PDIP and SO packages, re-quires significantly less PC board area than discrete multi op amp and Resistor LT1167 -1 offers the same performance as the LT1167 , but its input current characteristic at high common mode voltage better supports applications with high input imped-ance (see the Applications Information section).
