LTC6800 Rail-to-Rail, Input and Output, Instrumentation Amplifier Fae Tseru Dpircse Tnoi n 116dB CMRR Independent of Gain The LTC 6800 is a precision instrumentation amplifier. n Maximum Offset Voltage: 100V 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 40C to 125C Operation below 100V 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. a acilpp Tsnoi The differential inputs operate from rail-to-rail and the n Thermocouple Amplifiers single ended output swings from rail-to-rail. The LTC6800 n Electronic Scales is available in an MS8 surface mount package. For space n Medical Instrumentation limited applications, the LTC6800 is available in a 3mm n Strain Gauge Amplifiers 3mm 0.8mm dual fine pitch leadless package (DFN). n High Resolution Data Acquisition L, LT, LTC, LTM, Linear Technology and the Linear logo are registered trademarks of Linear Technology Corporation.
