DFN Packages The LTC®6800 is a precision instrumentation amplifier.
The CMRR is typically 116dB with a single 5V supply and is
independent of gain. The input offset voltage is guaranteed
below 100µV with a temperature drift of less than 250nV/°C.
The LTC6800 is easy to use; the gain is adjustable with
two external resistors, like a traditional op amp. Applications The LTC6800 uses charge balanced sampled data techniques to convert a differential input voltage into a single
ended signal that is in turn amplified by a zero-drift
operational amplifier. n n n n The differential inputs operate from rail-to-rail and the
single ended output swings from rail-to-rail. The LTC6800
is available in an MS8 surface mount package. For space
limited applications, the LTC6800 is available in a 3mm × …
