The AD8005 is an ultralow power, high-speed amplifier with 400μA power consumption and 270MHz of –3dB bandwidth. It is specified for single supply operation. It is suitable for signal conditioning, A/D buffer, power-sensitive, high-speed systems, battery powered equipment, loop/remote power systems, communication or video test systems and portable medical instruments.
The AD8005 is a current‑feedback operational amplifier designed for power‑sensitive, high‑speed applications such as portable video, medical, and communication systems. It operates from a single +5 V supply, consumes only 400 pA of quiescent current, and maintains a 270 MHz -3 dB bandwidth at a gain of +1.
The device is offered in three surface‑mount packages (8‑lead DIP, 8‑lead SOIC, 5‑lead SOT‑23) and is rated for an industrial temperature range of –40 °C to +85 °C. Detailed electrical characteristics, absolute maximum ratings, and typical performance graphs are provided in the datasheet.
| Small‑Signal Bandwidth (G=+1) | 225 MHz min, 270 MHz typ |
|---|---|
| Large‑Signal Bandwidth (G=+10) | 40 MHz typ |
| Quiescent Supply Current | 400 pA typ (475 pA max) |
| Operating Temperature Range | -40 °C to +85 °C |
| Input Voltage Noise (10 MHz) | 4.0 nV/√Hz |
| Total Harmonic Distortion (1 MHz, G=+2) | -63 dBc |
The AD8005 draws about 400 pA typical (up to 475 pA max) from the supply.
The amplifier is rated for –40 °C to +85 °C (industrial grade).
