The AD8515 is a rail-to-rail amplifier that can operate from a single-supply voltage as low as 1.8 V. The AD8515 single amplifier, available in 5-lead SOT-23 and SC70 packages, features ultralow input bias current, high input impedance, and wide gain-bandwidth.
The AD8515 is a low‑power CMOS rail‑to‑rail input/output operational amplifier from Analog Devices, designed for battery‑powered and portable applications such as communications devices, sensor interfaces, and laser scanners.
It operates from a single 1.8 V to 5 V supply, offers a typical offset voltage of 6 mV, input bias current as low as 30 pA, a slew rate of 27 V/µs, and a 5 MHz gain‑bandwidth product. The device is offered in compact 5‑lead SOT‑23 (RJ) and SC70 (KS) packages.
