1789fc
The LT1789-1/LT1789-10 are micropower, precision
instrumentation 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 non-
linearity 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
outputrangewhenanamplificationof10orgreaterisrequired,
allowingprecisesignalprocessingwhereotherinstrumenta-
tion 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
package, requiring significantly less PC board area than
discrete multi op amp and resistor designs.
