Wideband, Single-Supply

OPERATIONAL AMPLIFIERS

FEATURES

DESCRIPTION

● HIGH BANDWIDTH: 150MHz (G = +2)

● +3V TO +10V SUPPLY OPERATION

● ZERO POWER DISABLE (OPA635)

● INPUT RANGE INCLUDES GROUND

● 4.8V OUTPUT SWING ON +5V SUPPLY

● HIGH OUTPUT CURRENT: 80mA

● HIGH SLEW RATE: 250V/µs

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 INPUT VOLTAGE NOISE: 5.6nV/√HZ

● AVAILABLE IN SOT23 PACKAGE

Low-distortion operation is ensured by the high gain

bandwidth product (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, distor-

tion performance improves as the signal swing is de-

creased.

APPLICATIONS

● SINGLE-SUPPLY ADC INPUT BUFFERS

● SINGLE SUPPLY VIDEO LINE DRIVERS

● WIRELESS LAN IF AMPLIFIERS

● CCD IMAGING CHANNELS

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.

● LOW-POWER ULTRASOUND

+3V

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.
