The LT
®
1789-1/LT1789-10 are micropower, precision in-
strumentation amplifiers that are optimized for single supply
operation from 2.2V to 36V. The quiescent current is 95µA
max, the inputs common mode to ground and the output
swings within 110mV of ground. The gain is set with a single
external resistor for a gain range of 1 to 1000 for the LT1789-
1 and 10 to 1000 for the LT1789-10.
The high accuracy of the LT1789-1 (40ppm maximum
nonlinearity and 0.25% max gain error) is unmatched by
other micropower instrumentation amplifiers. The LT1789-10
maximizes both the input common mode range and dynamic
output range when an amplification of 10 or greater is
required, allowing precise signal processing where other
instrumentation amplifiers fail to operate. The LT1789-1/
LT1789-10 are laser trimmed for very low input offset
voltage, low input offset voltage drift, high CMRR and high
PSRR. The output can handle capacitive loads up to 400pF
(LT1789-1), 1000pF (LT1789-10) in any gain configuration
while the inputs are ESD protected up to 10kV (human body).
The LT1789-1/LT1789-10 are offered in the 8-pin SO pack-
age, requiring significantly less PC board area than discrete
multi op amp and resistor designs.
