Features

* (VS = 2.7V, TA = 25˚C, RL = 1kΩ to V+/2, AV = +1. Typical values unless specified). n
* 3dB BW 55MHz n Supply voltage range 2.5V to 12V n Slew rate 22V/µs n Supply current 650µA/channel n Output short circuit current 42mA ± 20mA n Linear output current n Input common mode voltage 0.3V beyond

Applications

* where previously only inferior devices could be used. Output voltage range extends to within 20mV of either supply rails, allowing wide dynamic range especially in low voltage applications. Even with low supply current of 650µA/amplifier, output current capability is kept at a respectable ± 20mA for
