DESCRIPTION

The OPA631 and OPA632 are low power, high-speed,
voltage-feedback amplifiers designed to operate on a
single +3V or +5V supply. Operation on ±5V or +10V
supplies is also supported. The input range extends
below ground and to within 1V of the positive supply.
Using complementary common-emitter outputs pro­vides an output swing to within 30mV of ground and
130mV of the positive supply. The high output drive
current and low differential gain and phase errors also
make them ideal for single-supply consumer video
products.

Low distortion operation is ensured by the high gain
bandwidth (68MHz) and slew rate (100V/µs), making
the OPA631 and OPA632 ideal input buffer stages to
3V and 5V CMOS converters. Unlike other low power,
single-supply amplifiers, distortion performance im­proves as the signal swing is decreased. A low 6nV
input voltage noise supports wide dynamic range op­eration. Channel multiplexing or system power reduc­tion can be achieved using the high speed disable line.
Power dissipation can be reduced to zero by taking the
disable line High.

The OPA631 and OPA632 are available in an industry­standard SO-8 package. The OPA631 is also available
in an ultra-small SOT23-5 package, while the OPA632
is available in the SOT23-6. Where higher full-power
bandwidth and lower distortion are required in a single­supply operational amplifier, consider the OPA634
and OPA635.

ELECTROSTATIC
DISCHARGE SENSITIVITY

Electrostatic discharge can cause damage ranging from perfor­mance degradation to complete device failure. Burr-Brown Corpo­ration recommends that all integrated circuits be handled and stored
using appropriate ESD protection methods.

ESD damage can range from subtle performance degradation to
complete device failure. Precision integrated circuits may be more
susceptible to damage because very small parametric changes
could cause the device not to meet published specifications.
