LTC6800 Rail-to-Rail Input and Output, Instrumentation Amplifier .. Features s s s s s s s s DESCRIPTIO 116d B CMRR Independent of Gain Maximum Offset Voltage: 100µV Maximum Offset Voltage Drift: 250n V/°C - 40°C to 125°C Operation Rail-to-Rail Input Range Rail-to-Rail Output Swing Supply Operation: 2.7V to 5.5V Available in an MS8 and 3mm × 3mm × 0.8mm DFN Packages The LTC®6800 is a precision instrumentation amplifier. The CMRR is typically 116d B 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 250n V/°C. The LTC6800 is easy to use; the gain is adjustable with two external resistors, like a traditional op amp. 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. 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 × 3mm × 0.8mm dual fine pitch leadless package (DFN). , LTC and LT are registered trademarks of Linear Technology Corporation.
