Low Power, Single-Supply

OPERATIONAL AMPLIFIERS

DESCRIPTION

FEATURES

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 pro-

vides 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.

● HIGH BANDWIDTH: 75MHz (G = +2)

● LOW SUPPLY CURRENT: 6mA

● ZERO POWER DISABLE (OPA632)

● +3V AND +5V OPERATION

● INPUT RANGE INCLUDES GROUND

● 4.8V OUTPUT SWING ON +5V SUPPLY

● HIGH SLEW RATE: 100V/µs

● LOW INPUT VOLTAGE NOISE: 6nV/√HZ

● AVAILABLE IN SOT23 PACKAGE

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 im-

proves as the signal swing is decreased. A low 6nV

input voltage noise supports wide dynamic range op-

eration. Channel multiplexing or system power reduc-

tion can be achieved using the high speed disable line.

Power dissipation can be reduced to zero by taking the

disable line High.

APPLICATIONS

● SINGLE SUPPLY ADC INPUT BUFFER

● SINGLE SUPPLY VIDEO LINE DRIVER

● CCD IMAGING CHANNELS

● LOW POWER ULTRASOUND

● PLL INTEGRATORS

● PORTABLE CONSUMER ELECTRONICS

The OPA631 and OPA632 are available in an industry-

standard 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 single-

supply operational amplifier, consider the OPA634

and OPA635.
