Dual, Low-Power, Single-Supply Wideband Operational Amplifier

The OPA2830 is a dual, low-power,

single-supply, wide-band, voltage-feedback amplifier designed to operate on a single

3V or 5V supply. The device also supports operation on ±5V or +10V supplies. The

input range extends below the negative supply and to within 1.8V of the positive

supply. Using complementary common-emitter outputs provides an output swing to

within 25mV of either supply while driving 150Ω. High output drive current (±75mA)

and low differential gain and phase errors also make this device an excellent choice

for single-supply consumer video products.

Low distortion operation is provided

by the high gain bandwidth product (100MHz) and slew rate (500V/µs), making the

OPA2830 an excellent input buffer stage to 3V and 5V CMOS ADCs. Unlike other

low-power, single-supply amplifiers, distortion performance improves as the signal

swing decreases. A low 9.2nV/√Hz input voltage noise supports wide dynamic range

operation.

The OPA2830 is available in an

industry-standard SO-8 package. The OPA2830 is also available in a small VSSOP-8

package. For fixed-gain and line driver applications, consider the OPA2832.
