DESCRIPTION
The OPA634 and OPA635 are low power, voltage-
feedback, high-speed amplifiers designed to operate on
+3V or +5V single-supply voltages. Operation on ±5V
or +10V supplies is also supported. The input range
extends below ground and to within 1.2V of the positive
supply. Using complementary common-emitter outputs
provides an output swing to within 30mV of ground and
140mV of positive supply. The high output drive cur-
rent, low differential gain and phase errors make them
ideal for single-supply composite video line driving.
Low distortion operation is ensured by the high gain
bandwidth (140MHz) and slew rate (250V/µs). This
makes the OPA634 and OPA635 ideal input buffer
stages to 3V and 5V CMOS converters. Unlike other low
power, single-supply operational amplifiers, distortion
performance improves as the signal swing is decreased.
A low 5.6nV input voltage noise supports wide dynamic
range operation. Multiplexing or system power reduc-
tion can be achieved using the high-speed disable line
with the OPA635. Power dissipation can be reduced to
zero by taking the disable line High.
The OPA634 and OPA635 are available in an industry
standard SO-8 package. The OPA634 is also available in
an ultra-small SOT23-5 package, while the OPA635 is
available in the SOT23-6. Where lower supply current
and speed are required, consider the OPA631 and
OPA632.
