DESCRIPTIO

The LTC
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
requires no external clock, while the LTC2053-SYNC has
a CLK pin to synchronize to an external clock.
The LTC2053 is available in an MS8 surface mount pack-
age. For space limited applications, the LTC2053 is avail-
able in a 3mm × 3mm × 0.8mm dual fine pitch leadless
package (DFN).
