Input Offset Voltage (LMP7701): ±200-µV

supply voltage range. The LMP770x are part of the

•

Input Offset Voltage (LMP7702/LMP7704): ±220-

applications.

µV (Maximum)

•

Input Bias Current: ±200 fA

The specified low-offset voltage of less than ±200 µV,

along with the specified low input bias current of less
