Single Resistor Gain

Programmable, Precision

Instrumentation Amplifier

FEATURES

DESCRIPTION

The 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 7.5nV/√Hz (at 1kHz)

isnotcompromisedbylowpowerdissipation(0.9mAtypical

for ±2.3V to ±15V supplies).

■

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

■

Gain Error: G = 10, 0.08% Max

■

Gain Nonlinearity: G = 10, 10ppm Max

Input Offset Voltage: G = 10, 60µV Max

■

Input Offset Voltage Drift: 0.3µV/°C Max

■

Input Bias Current: 350pA Max

PSRR at G = 1: 105dB Min

CMRR at G = 1: 90dB Min

Supply Current: 1.3mA Max

Wide Supply Range: ±2.3V to ±18V

1kHz Voltage Noise: 7.5nV/√Hz

0.1Hz to 10Hz Noise: 0.28µV_P-P

Available in 8-Pin PDIP and SO Packages

Meets IEC 1000-4-2 Level 4 ESD Tests with

Two External 5k Resistors

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

LT1167 is laser trimmed for very low input offset voltage

(40µV max), drift (0.3µV/°C), high CMRR (90dB, G = 1) and

PSRR (105dB, G = 1). 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 specification.
