LMH6639 Description
LMH6639 190MHz Rail-to-Rail Output Amplifier with Disable July 2003 LMH6639 190MHz Rail-to-Rail Output Amplifier with Disable General .
The LMH6639 is a voltage feedback operational amplifier with a rail-to-rail output drive capability of 110mA.
LMH6639 Features
* (VS = 5V, Typical values unless specified) n Supply current (no load) 3.6mA n Supply current (off mode) 400µA n Output resistance (closed loop 1MHz) 0.186Ω n
* 3dB BW (AV = 1) 190MHz n Settling time 33nsec n Input common mode voltage
* 0.2V to 4V n Output voltage swing 40mV from rails
LMH6639 Applications
* The LMH6639 offers a slew rate of 172V/µs resulting in a full power bandwidth of approximately 28MHz. The TON value of 83nsec combined with a settling time of 33nsec makes this device ideally suited for multiplexing applications. Careful attention has been paid to ensure device stability under all
