OP495GSZ

OP495 is a quad channel, CBCMOS operational amplifier. Rail-to-rail output swing combined with dc accuracy is the key feature. By using a bipolar front end, lower noise and higher accuracy than those of CMOS designs have been achieved. Both input and output ranges include the negative supply, providing the user with zero-in/zero-out capability. It is an ideal driver for power transistors and H bridges. This allows designs to achieve higher efficiencies and to transfer more power to the load than previously possible without the use of discrete components. Stability while driving capacitive loads is another benefit of this design over CMOS rail-to-rail amplifiers. This is useful for driving coax cable or large FET transistors. It is widely used in application such as battery-operated instrumentation, servo amplifiers, actuator drives, sensor conditioners, power supply control etc.
