FEATURES
DESCRIPTIOU
APPLICATIU
TYPICAL APPLICATIOU
The LTC
2053 is a high precision instrumentation ampli-
fier. The CMRR is typically 116dB with a single or dual 5V
supply and is independent of gain. The input offset voltage
is guaranteed below 10
μ
V with a temperature drift of less
than 50nV/
°
C. The LTC2053 is easy to use; the gain is
adjustable with two external resistors, like a traditional
op amp.
The LTC2053 uses charge balanced sampled data tech-
niques to convert a differential input voltage into a single
ended signal that is in turn amplified by a zero-drift
operational amplifier.
The differential inputs operate from rail-to-rail and the
single ended output swings from rail-to-rail. The LTC2053
can be used in single supply applications, as low as 2.7V.
It can also be used with dual
±
5.5V supplies. The LTC2053
is available in an MS8 surface mount package. For space
limited applications, the LTC2053 is available in a

0.8mm dual fine pitch leadless package
