The MAX4380-MAX4384 family of op amps are unity-gain-stable devices that combine high-speed performance, Rail-to-Rail® outputs, and high-impedance disable mode. These devices operate from a +4.5V to +11V single supply or from ±2.25V to ±5.5V dual supplies. The common-mode input voltage range extends beyond the negative power-supply rail (ground in single-supply applications). The MAX4380-MAX4384 require only 5.5mA of quiescent supply current per op amp while achieving a 210MHz -3dB bandwidth, 55MHz 0.1dB gain flatness and a 485V/µs slew rate. These devices are an excellent solution in low-power/low-voltage systems that require wide bandwidth, such as video, communications, and instrumentation.
The MAX4380‑MAX4384 family are unity‑gain‑stable, single‑supply voltage‑feedback amplifiers that combine high speed, rail‑to‑rail outputs and a high‑impedance disable mode. They operate from +4.5 V to +11 V (or ±2.25 V to ±5.5 V) and draw only 5.5 mA per device, making them suitable for low‑power video, communications and instrumentation applications.
Key features include a 210 MHz -3 dB bandwidth, 485 V/µs slew rate, low distortion, multiple package options (SC70, SOT‑23, µMAX, TSSOP, QSOP) and a disable pin that places the outputs in a high‑impedance state.
