The MAX4389/MAX4390/MAX4392–MAX4396 family of op amps are unity-gain stable devices that combine high-speed performance, rail-to-rail outputs, and disable mode. These devices are targeted for applications where an input or an output is exposed to the outside world, such as video and communications. The MAX4389/MAX4390/MAX4392–MAX4396 operate from a single 4.5V to 11V supply or from dual ±2.25V to ±5.5V supplies. The common-mode input voltage range extends to the negative power-supply rail (ground in single-supply applications). The MAX4389/MAX4390/ MAX4392–MAX4396 consume only 5.5mA of quiescent supply current per amplifier while achieving an 85MHz -3dB bandwidth, 27MHz 0.1dB gain flatness, and a 500V/µs slew rate. Disable mode sets the outputs to high impedance while consuming only 450µA of current. The MAX4389 single, MAX4393 dual, MAX4394 triple, and MAX4396 quad include disable capabilities. The MAX4389 and MAX4390 are available in ultra-small, 6-pin SC70 packages.
The MAX4389‑MAX4396 family are unity‑gain stable, high‑speed operational amplifiers with rail‑to‑rail outputs and a disable mode that places the outputs in high‑impedance. They are intended for video, communications, and other applications where inputs or outputs are exposed to the external world.
These devices operate from a single 4.5 V to 11 V supply or dual ±2.25 V to ±5.5 V supplies, support multiple ultra‑small packages (SC70, SOT23, µMAX, TSSOP), and feature a 450 µA disable current, 85 MHz –3 dB bandwidth, 500 V/µs slew rate, and ±50 mA output drive.
