The ADA4665-2 is a high voltage, high frequency, CMOS operational amplifier that features low power, low input bias current, wide bandwidth, high gain bandwidth product and single supply operation.
The ADA4665-2 is a rail‑to‑rail input/output dual operational amplifier optimized for low‑power designs. It operates from a single supply of 5 V to 16 V or a dual supply of ±2.5 V to ±8 V, offering typical supply currents of 290 µA per amplifier at 16 V and 270 µA at 5 V. Key electrical characteristics include a typical offset voltage of 4 mV, input bias current of 1 pA, bandwidth of 1.2 MHz, and slew rate of 1 V/µs.
Typical applications are portable systems, high‑density power‑budget designs, medical equipment, physiological measurement, precision references, sensor front‑ends, transimpedance amplifiers, and level‑shifting circuits. The device is offered in standard 8‑lead SOIC and MSOP packages and complies with JEDEC standards.
