LT1167ACS8#PBF

Product Summary

The LT1167ACS8#PBF is a Precision Instrumentation Amplifier. The LT1167ACS8#PBF is a low power, precision instrumentation amplifier that requires only one external resistor to set gains of 1 to 10,000. The high accuracy of 10ppm maximum nonlinearity and 0.08% 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 LT1167ACS8#PBF is laser trimmed for very low input offset voltage (40μV max), drift (0.3μV/℃), high CMRR (90dB, G = 1) and PSRR (105dB, G = 1). Low input bias currents of 350pA max are achieved with the use of super beta 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 LT1167ACS8#PBF with two external 5k resistors passes the IEC 1000-4-2 level 4 specification. The LT1167ACS8#PBF, offered in 8-pin PDIP and SO packages, requires significantly less PC board area than discrete multi op amp and resistor designs. These advantages make the LT1167ACS8#PBF the most cost effective solution for precision instrumentation amplifier applications. The applications of the LT1167ACS8#PBF include Bridge Amplifiers, Strain Gauge Amplifiers, Thermocouple Amplifiers, Differential to Single-Ended Converters and Medical Instrumentation.
