P-P

The LT

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)

is not compromised by low power dissipation (0.9mA typical

for 2.3V to 15V supplies).

The part’s high accuracy (10ppm maximum nonlinearity,

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

(40 V max), drift (0.3 V/ 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.

The LT1167, 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 LT1167 the

most cost effective solution for precision instrumentation

amplifier applications.
