Rail-to-rail output swing combined with dc accuracy are the key features of the OP495 quad and OP295 dual CBCMOS operational amplifiers. 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, pro
viding 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.
