GENERAL DESCRIPTION
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 of 3.3 V systems such as
lithium batteries, the OP295/OP495 is specified for 3 V operation.
Maximum offset voltage is specified at 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 15 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
(–40∞C to +125∞C) 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.
