Operating from a 2.7-V to 12-V supply range, the LMP8645 accepts input signals with a common-mode voltage range of –2 V to 42 V, while the LMP8645HV accepts input signals with a common-mode voltage range of –2 V to 76 V. The LMP8645 and LMP8645HV have adjustable gain, set by a single resistor, for applications where supply current and high common-mode voltage are the determining factors.
