... The CMRR is typically 116dB with a single or dual 5V supply and is independent of gain. The input offset voltage is guaranteed below 10 V 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- ...

... RG pin is the negative input of this op amp and allows external programmability of the DC gain. Simple filtering can be realized by using an external capacitor across the feedback resistor. Input Voltage Range The input common mode voltage range of the LTC2053 is rail-to-rail. However, the following equation limits the size of the differential input voltage: – + ...
