SBOS196G – DECEMBER 2001 – REVISED NOVEMBER 2008

Wideband, Unity-Gain Stable, FET-Input

OPERATIONAL AMPLIFIER

FEATURES

DESCRIPTION

● 500MHz UNITY-GAIN BANDWIDTH

The OPA656 combines a very wideband, unity-gain stable,

voltage-feedback op amp with a FET-input stage to offer an

ultra high dynamic-range amplifier for ADC (Analog-to-Digital

Converter) buffering and transimpedance applications. Extremely

low DC errors give good precision in optical applications.

● LOW INPUT BIAS CURRENT: 2pA

● LOW OFFSET AND DRIFT: ±0.25mV, ±2µV/°C

● LOW DISTORTION: 74dB SFDR at 5MHz

● HIGH OUTPUT CURRENT: 70mA

The high unity-gain stable bandwidth and JFET input allows

exceptional performance in high-speed, low-noise integrators.

● LOW INPUT VOLTAGE NOISE: 7nV/√Hz

The high input impedance and low bias current provided by

the FET input is supported by the ultra-low 7nV/√Hz input

voltage noise to achieve a very low integrated noise in

wideband photodiode transimpedance applications.

APPLICATIONS

● WIDEBAND PHOTODIODE AMPLIFIERS

● SAMPLE-AND-HOLD BUFFERS

● CCD OUTPUT BUFFERS

Broad transimpedance bandwidths are achievable given the

OPA656’s high 230MHz gain bandwidth product. As shown

below, a –3dB bandwidth of 1MHz is provided even for a high

1MΩ transimpedance gain from a 47pF source capacitance.

● ADC INPUT BUFFERS

● WIDEBAND PRECISION AMPLIFIERS

● TEST AND MEASUREMENT FRONT ENDS
