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.
