ADA4899-1YRDZ

Overview

The ADA4899-1 is a high-speed, unity-gain stable voltage feedback operational amplifier featuring ultralow noise and distortion. It operates on supply voltages from 4.5 V to 12 V with a quiescent current of 14.7 mA. The device provides a –3 dB bandwidth of 600 MHz at G = +1 and a slew rate of 310 V/µs. Input offset voltage is 230 µV maximum, and input bias current is 100 nA. Harmonic distortion reaches –117 dBc at 1 MHz. It includes a dedicated DISABLE pin for output tri-stating or bias current cancellation.

Feature Summary

• Ultralow noise performance with 1 nV/√Hz input voltage noise density
• High speed operation with 600 MHz bandwidth and 310 V/µs slew rate
• Dedicated DISABLE pin enables high-impedance output state or input bias current cancellation mode
• Available in 8-lead SOIC and LFCSP packages with exposed thermal paddle

Applications

• Analog-to-digital drivers
• Instrumentation
• Filters
• IF and baseband amplifiers
• DAC buffers

Procurement Notes

Verify the package type (SOIC or LFCSP) and ordering suffix against the manufacturer's official documentation before procurement. Confirm that the specific revision matches the required specifications. Ensure proper handling procedures are followed due to ESD sensitivity. Check availability through authorized distributors as stock levels fluctuate.

Selection Notes

Select this component for applications requiring both high bandwidth and low noise in a unity-gain configuration. The disabled pin allows for time-interleaved driving of ADCs or bias current reduction. Consider the exposed pad requirement for thermal management and PCB layout optimization when choosing between package options.
