Rail-to-rail output swing combined with dc accuracy are the key

features of the OP495 quad and OP295 dual CBCMOS opera-

tional 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.

that require driving inductive loads, such as transformers, in-

creases in efficiency are also possible. Stability while driving

capacitive loads is another benefit of this design over CMOS

rail-to-rail amplifiers. T his is useful for driving coax cable or

large FET transistors. T he OP295/OP495 is stable with loads in

excess of 300 pF.

Maximum offset voltage is specified at 300 µV for +5 volt opera-

tion, and the open-loop gain is a minimum of 1000 V/mV. T his

yields performance that can be used to implement high accuracy

systems, even in single supply designs.

T he OP295 and OP495 are specified over the extended indus-

trial (–40°C to +125°C) temperature range. OP295s are avail-

able in 8-pin plastic and ceramic DIP plus SO-8 surface mount

packages. OP495s are available in 14-pin plastic and SO-16

surface mount packages. Contact your local sales office for

MIL-ST D-883 data sheet.

T he ability to swing rail-to-rail and supply +15 mA to the load

makes the OP295/OP495 an ideal driver for power transistors

and “H” bridges. T his allows designs to achieve higher efficien-

cies and to transfer more power to the load than previously pos-

sible without the use of discrete components. For applications
