DESCRIPTIO

The LT

strumentation amplifiers that are optimized for single supply

operation from 2.2V to 36V. The quiescent current is 95 A

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.
