The AD8541/AD8542/AD8544 are single, dual, and quad rail-to-rail input and output, single-supply amplifiers featuring very low supply current and 1 MHz bandwidth. They are guaranteed to operate from a 2.7 V single supply as well as a 5 V supply. These parts provide 1 MHz bandwidth at a low current consumption of 45 μA per amplifier.
The AD8541, AD8542 and AD8544 are single‑, dual‑ and quad‑channel rail‑to‑rail input and output CMOS amplifiers. They operate from a single supply of 2.7 V to 5.5 V, draw low supply current (45 µA per amplifier), and provide 1 MHz bandwidth.
These parts are specified over an extended industrial temperature range (‑40 °C to +125 °C) and are qualified for automotive applications. Package options include 5‑lead SC70, 5‑lead SOT‑23, 8‑lead SOIC/MSOP/TSSOP and 14‑lead SOIC/TSSOP, all available in tape‑and‑reel form.
