LT1168

Low Power, Single

Resistor Gain Programmable,

Precision Instrumentation Amplifier

DESCRIPTIO

The LT

1168 is a micropower, precision instrumentation am-

plifier that requires only one external resistor to set gains of

1 to 10,000. The low voltage noise of 10nV/√Hz (at 1kHz) is

not compromised by low power dissipation (350µA typical for

±15V

supplies). The wide supply range of

±2.3V

±18V

allows

the LT1168 to fit into a wide variety of industrial as well as

battery-powered applications.

The high accuracy of the LT1168 is due to a 20ppm maximum

nonlinearity and 0.4% max gain error (G = 10). Previous mono-

lithic instrumentation amps cannot handle a 2k load resistor

whereas the nonlinearity of the LT1168 is specified for loads

as low as 2k. The LT1168 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 process-

ing. 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 LT1168 with two external 5k

resistors passes the IEC 1000-4-2 level 4 specification.

The LT1168 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 LT1168 the most cost effective solution for precision

instrumentation amplifier applications.
