The MAX4165-MAX4169 family of operational amplifiers combines excellent DC accuracy with high output current drive, single-supply operation, and rail-to-rail inputs and outputs.
The MAX4165‑MAX4169 family combines high DC accuracy, rail‑to‑rail input and output, and up to 80 mA output current. They operate from a single +2.7 V to +6.5 V supply (or ±1.35 V to ±3.25 V dual supplies) and draw only 1.2 mA typical supply current.
Key features include a low‑power shutdown mode (38 µA), 5 MHz gain‑bandwidth product, 250 µV offset voltage, and 120 dB voltage gain. The devices are offered in compact 5‑pin SOT‑23 (MAX4165) and 2 mm × 2 mm × 0.8 mm µDFN (MAX4166) packages, making them suitable for portable audio and battery‑powered applications.

Each amplifier can deliver a minimum of 80 mA output current.
In shutdown mode the supply current is reduced to 38 µA per amplifier.
They operate from a single‑supply voltage of +2.7 V to +6.5 V, or from dual supplies of ±1.35 V to ±3.25 V.
MAX4165 is offered in a 5‑pin SOT‑23 package, while MAX4166 is available in a 2 mm × 2 mm × 0.8 mm µDFN package.
