FEATURES

DESCRIPTIO

■

Supply Current: 530µA Max

■

Meets IEC 1000-4-2 Level 4 (±15kV) ESD Tests

with Two External 5k Resistors

Single Gain Set Resistor: G = 1 to 10,000

Gain Error: G = 10, 0.4% Max

Input Offset Voltage Drift: 0.3µV/°C Max

Gain Nonlinearity: G = 10, 20ppm Max

Input Offset Voltage: 40µV Max

Input Bias Current: 250pA Max

PSRR at A_V=1: 103dB Min

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

notcompromisedbylowpowerdissipation(350µAtypicalfor

±15Vsupplies).Thewidesupplyrangeof±2.3Vto±18Vallows

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

battery-powered applications.

ThehighaccuracyoftheLT1168isduetoa20ppmmaximum

nonlinearityand0.4%maxgainerror(G=10).Previousmono-

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

offsetvoltage(40µVmax),drift(0.3µV/°C),highCMRR(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.

CMRR at A_V= 1: 90dB Min

Wide Supply Range: ±2.3V to ±18V

1kHz Voltage Noise: 10nV/√Hz

0.1Hz to 10Hz Noise: 0.28µV_P-P
