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.
Maximum offset voltage is specified at 300
μ
V 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 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
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.
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
