DFN Packages

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 10µV 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

3mm

0.8mm dual fine pitch leadless package

(DFN).
