By using a bipolar front end, lower noise and higher accuracy than that of CMOS designs has been achieved. Both input and output ranges include the negative supply, providing the user “zero-in/zero-out” capability. For users of 3.3 volt systems such as lithium batteries, the OP295/OP495 is specified for three volt operation. Maximum offset voltage is specified at 300 µV for +5 volt operation, and the op...
