TYPICAL APPLICATION
FEATURES DESCRIPTION
Single Resistor Gain
Programmable, Precision
Instrumentation Amplifier
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) 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. 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.
The LT1167, offered in 8-pin PDIP and SO packages, re-
quires significantly less PC board area than discrete multi
op amp and resistor designs.
The LT1167-1 offers the same performance as the LT1167,
but its input current characteristic at high common mode
voltage better supports applications with high input imped-
ance (see the Applications Information section).
