LTC6800 Rail-to-Rail, Input and Output, Instrumentation Amplifier FeaTures DescripTion n
116dB CMRR Independent of Gain
The LTC®6800 is a precision instrumentation amplifier. n
Maximum Offset Voltage: 100µV
The CMRR is typically 116dB with a single 5V supply and is n
Maximum Offset Voltage Drift: 250nV/°C
independent of gain. The input offset voltage is guaranteed n
–40°C to 125°C Operation
below 100µV with a temperature drift of less than 250nV/°C. n Rail-to-Rail Input Range The LTC6800 is easy to use; the gain is adjustable with n Rail-to-Rail Output Swing two external resistors, like a traditional op amp. n Supply Operation: 2.7V to 5.5V The LTC6800 uses charge balanced sampled data tech- n Available in MS8 and 3mm × 3mm × 0.8mm niques to convert a differential input voltage into a single DFN Packages ended signal that is in turn amplified by a zero-drift operational amplifier. applicaTions n The differential inputs operate from rail-to-rail and the Thermocouple Amplifiers n single ended output swings from rail-to-rail. The LTC6800 Electronic Scales n is available in an MS8 surface mount package. For space Medical Instrumentation n limited applications, the LTC6800 is available in a 3mm × Strain Gauge Amplifiers n 3mm × 0.8mm dual fine pitch leadless package (DFN).
