OPA657

SBOS197B – DECEMBER 2001 – REVISED MAY 2004

1.6GHz, Low-Noise, FET-Input

OPERATIONAL AMPLIFIER

FEATURES

DESCRIPTION

The OPA657 combines a high gain bandwidth, low distor-tion,

voltage-feedback op amp with a low voltage noise JFET-input

stage to offer a very high dynamic range amplifier for high

precision ADC (Analog-to-Digital Converter) driving or wideband

transimpedance applications. Photodiode applications will see

improved noise and bandwidth using this decompensated,

high gain bandwidth amplifier.

● HIGH GAIN BANDWIDTH PRODUCT: 1.6GHz

● HIGH BANDWIDTH 275MHz (G = +10)

● LOW INPUT OFFSET VOLTAGE: ±0.25mV

● LOW INPUT BIAS CURRENT: 2pA

● LOW INPUT VOLTAGE NOISE: 4.8nV/ Hz

● HIGH OUTPUT CURRENT: 70mA

Very low level signals can be significantly amplified in a single

OPA657 gain stage with exceptional bandwidth and accuracy.

Having a high 1.6GHz gain bandwidth product will give >

10MHz signal bandwidths up to gains of 160V/V (44dB). The

very low input bias current and capacitance will support this

performance even for relatively high source impedances.

● FAST OVERDRIVE RECOVERY

APPLICATIONS

● WIDEBAND PHOTODIODE AMPLIFIER

● WAFER SCANNING EQUIPMENT

● ADC INPUT AMPLIFIER

Broadband photodetector applications will benefit from the low

voltage noise JFET inputs for the OPA657. The JFET input

contributes virtually no current noise while for broadband

applications, a low voltage noise is also required. The low

4.8nV/ Hz input voltage noise will provide exceptional input

sensitivity for higher bandwidth applications. The example

shown below will give a total equivalent input noise current of

1.8pA/ Hz over a 10MHz bandwidth.

● TEST AND MEASUREMENT FRONT END

● HIGH GAIN PRECISION AMPLIFIER
