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, providing the user "zero-in/zero-out" capability. For users 3.3 V systems such as lithium batteries, the OP295/OP495 is specified for 3 V operation. Maximum offset voltage is specified 300 mV for 5 V operation, and the open-loop gain is a minimum of 1000 V/mV. This yields performance that can be used to implement high accuracy systems, even in single-supply designs. The ability to swing rail-to-rail and supply mA to the load makes the OP295/OP495 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. For applications that require

driving inductive loads, such as transformers, increases in efficiency are also possible. 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. The OP295/OP495 is stable with loads in excess of 300 pF. The OP295 and OP495 are specified over the extended industrial to +125C) temperature range. OP295s are available in 8-lead plastic DIP plus SO-8 surface-mount packages. OP495s are available in 14-lead plastic and SO-16 surface-mount packages. Contact your local sales office for MIL-STD-883 data sheet.
