LT1168CN8 Product Details

The high accuracy of the LT1168CN8 is due to a 20ppm maximum nonlinearity and 0.4% max gain error (G = 10). Previous monolithic instrumentation amps cannot handle a 2k load resistor whereas the nonlinearity of the LT1168CN8 is specified for loads as low as 2k. The LT1168CN8 is laser trimmed for very low input offset voltage (40µV max), drift (0.3µV/°C), high CMRR (90dB, G = 1) and PSRR (103dB, G = 1). Low input bias currents of 250pA 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 LT1168CN8 with two external 5k resistors passes the IEC 1000-4-2 level 4 specification.

The LT1168CN8 is a pin-for-pin improved second source for the AD620 and INA118. The LT1168, offered in 8-pin PDIP and SO packages, requires significantly less PC board area than discrete op amp resistor designs. These advantages make the LT1168CN8 the most cost effective solution for precision instrumentation amplifier applications.
