This is a high voltage, low noise, low distortion, unity-gain stable, high speed op amp. It provides single 8-lead and dual 8-lead packages.
The ADA4898‑1 and ADA4898‑2 are ultralow‑noise, low‑distortion, unity‑gain stable voltage‑feedback op‑amps designed for 16‑bit and 18‑bit systems. They operate from a wide supply range of +5 V to +16 V, offer a 65 MHz –3 dB bandwidth at unity gain, and include a power‑down pin for low‑power operation.
The document provides detailed electrical specifications, absolute maximum ratings, thermal resistance data, pin‑out diagrams, typical performance curves, and application guidance for instrumentation, active filters, DAC buffers, SAR‑ADC drivers, and optoelectronics.
| Supply Voltage Range | +5 V to +16 V |
|---|---|
| -3 dB Bandwidth (G=+1, 100 mV p‑p) | 65 MHz |
| Input Voltage Noise (1 kHz) | 0.9 nV/√Hz |
The device operates from +5 V up to +16 V.
The input voltage noise is 0.9 nV/√Hz at 1 kHz.
When the PD pin is driven below –14 V the device powers down; applying 2 V to 13 V enables the chip.
