DescripTion  
FeaTures  
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 op-  
erational amplifier.

Available in MS8 and 3mm × 3mm × 0.8mm  
DFN Packages  
The differential inputs operate from rail-to-rail and the  
single-endedoutputswingsfromrail-to-rail.TheLTC2053  
can be used in single-supply applications, as low as 2.7V.  
It can also be used with dual 5.5V supplies. The LTC2053  
requires no external clock, while the LTC2053-SYNC has  
a CLK pin to synchronize to an external clock.
