AD8003 is a triple gain, 1.5 GHz high speed op amp from Analog Devices. It features a bandwidth of up to 1650 MHz, a settling time of 12 ns to 0.1%, 2 V step, and a high output drive of 100 mA. It is ideal for high resolution video graphics, professional video, consumer video, high speed instrumentation, and multiplexing applications.
The AD8003 is a triple ultrahigh‑speed current‑feedback operational amplifier built on Analog Devices' eXtra Fast Complementary Bipolar (XFCB) process. It offers a 1.5 GHz –3 dB bandwidth, 4300 V/µs slew rate, and low offset and noise, making it suitable for high‑resolution video, professional video, consumer video, and high‑speed instrumentation applications.
Key features include a wide supply range (+5 V to ±5 V), 100 mA output drive capability, low input bias current (7 µA typical), and excellent dc precision (0.7 mV offset typical). The datasheet provides detailed specifications, absolute maximum ratings, thermal resistance data, PCB layout guidelines, and recommended power‑supply bypassing techniques to ensure optimal performance.
