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.  
NC = NO CONNECT  
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
