AD8099ACP-R2

Instrumentation, Op Amps, Buffer Amps Overview

The AD8099 is an ultralow noise and distortion voltage feedback operational amplifier designed for high-speed signal processing. It features a gain bandwidth product of 3.8 GHz, with −3 dB bandwidths of 700 MHz at G = +2 and 550 MHz at G = +10. The device offers a slew rate of 475 V/µs at G = +2 and 1350 V/µs at G = +10. Input voltage noise is 0.95 nV/√Hz, while harmonic distortion reaches −92 dBc (2nd harmonic) and −105 dBc (3rd harmonic) at 10 MHz with G = +2. It operates on supply voltages from 5 V to 12 V with a quiescent current of 15 mA.

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific package variant against the datasheet ordering guide, as the AD8099 is available in both SOIC-EP and LFCSP packages with distinct pinouts. Confirm that the required gain configuration matches the external compensation requirements specified for the selected package type. Ensure the operating temperature range aligns with the extended industrial rating of −40°C to +125°C.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component for applications requiring minimal trade-offs between bandwidth and distortion at low gains. The external compensation network allows designers to tailor the closed-loop response for specific gain settings. Consider the package choice carefully, as the SOIC and LFCSP variants exhibit different capacitive load driving capabilities due to output inductance differences.

Instrumentation, Op Amps, Buffer Amps Part Context

The AD8099 is part of Analog Devices' portfolio of high-speed voltage feedback amplifiers. It is engineered using the extra fast complimentary bipolar (XFCB) process to achieve performance levels previously associated with fully uncompensated amplifiers. The device is suitable for 16-bit and 18-bit systems where precision and speed are critical.

Instrumentation, Op Amps, Buffer Amps FAQ

How does the DISABLE pin function?

Pulling the DISABLE pin low activates a high-impedance state. Pulling it within 0.7 V of the positive supply enables input bias current cancellation, reducing bias current below 200 nA.

What is the purpose of external compensation?

External compensation allows the user to set the gain bandwidth product and optimize the closed-loop response for minimal peaking, particularly at gains lower than 15.
