ADA4627-1/ADA4637-1

Data Sheet

DECOMPENSATED OP AMPS

The ADA4637-1 is a decompensated op amp, and, as such, must

always be operated at a noise gain of 5 or greater. See tutorial

MT-033, Voltage Feedback Op Amp Gain and Bandwidth, at

www.analog.com for more information.

DRIVING CAPACITIVE LOADS

Adding capacitance to the output of any op amp results in

additional phase shift, which reduces stability and leads to

overshoot or oscillation.

The ADA4627-1/ADA4637-1 have a high phase margin and low

output impedance, so they can drive reasonable values of

capacitance. This is a common situation when an amplifier is used

to drive the input of switched capacitor ADCs. For other

considerations and various circuit solutions, see the Analog

Dialogue article titled Ask the Applications Engineer-25, Op

Amps Driving Capacitive Loads.
