The PA09 is a high voltage, high output current operational amplifier optimized to drive a variety of loads from DC through the video frequency range. It features power MOS technology with a 2A peak rating, a high gain bandwidth product of 150MHz, a very fast slew rate of 200V/µs, a protected output stage with thermal shutoff, excellent linearity with Class A/B output, a wide supply range of ±12V to ±40V, and low bias current and low noise with FET input.
The PAO9 is a high‑voltage, high‑output‑current operational amplifier optimized for video‑frequency loads. It features a dual monolithic FET input, a class A/B Power MOS output stage, thermal shut‑off protection, and a wide supply range of +12 V to +40 V.
The datasheet provides absolute maximum ratings, detailed electrical specifications, typical performance graphs, and extensive operating‑considerations such as safe operating area, supply bypassing, grounding, compensation, and thermal shutdown protection.
| Supply voltage range | +12 V to +40 V |
|---|---|
| Maximum supply voltage (dual rails) | 80 V |
| Peak output current | 5 A |
| Power dissipation (internal) | 73 W |
| Gain‑bandwidth product | 150 MHz |
| Slew rate (C = 5 pF) | 220 V/µs |
| Quiescent current | 85 mA (typical) |

The PAO9 can operate with up to 80 V between the positive and negative supply rails.
The typical quiescent current is about 85 mA.
A slew rate of 220 V/µs is achieved with a 5 pF compensation capacitor.
The gain‑bandwidth product is 150 MHz.
