OPA171 OPA2171 OPA4171 www.ti.com SBOS516D – SEPTEMBER 2010 – REVISED SEPTEMBER 2012 APPLICATION INFORMATION The OPAx171 family of operational amplifiers provide high overall performance, making them ideal for many general-purpose applications. The excellent offset drift of only 2µV/°C provides excellent stability over the entire temperature range. In addition, the device offers very good overall performance with high CMRR, PSRR, and AOL.

OPA171 OPA2171 OPA4171 SBOS516D – SEPTEMBER 2010 – REVISED SEPTEMBER 2012 www.ti.com CAPACITIVE LOAD AND STABILITY The dynamic characteristics of the OPAx171 have been optimized for commonly encountered operating conditions. The combination of low closed-loop gain and high capacitive loads decreases the phase margin of the amplifier and can lead to gain peaking or oscillations. As a result, heavier capacitive loads must be isolated from the output.
