OPA171-Q1 www.ti.com SBOS556A – JUNE 2011 – REVISED SEPTEMBER 2012 APPLICATION INFORMATION The OPA171-Q1 operational amplifier provides high overall performance, making it 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-Q1 SBOS556A – JUNE 2011 – REVISED SEPTEMBER 2012 www.ti.com CAPACITIVE LOAD AND STABILITY ELECTRICAL OVERSTRESS The dynamic characteristics of the OPA171-Q1 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.
PAGE 13
OPA171-Q1 www.ti.com SBOS556A – JUNE 2011 – REVISED SEPTEMBER 2012 If there is an uncertainty about the ability of the supply to absorb this current, external zener diodes may be added to the supply pins. The zener voltage must be selected such that the diode does not turn on during normal operation. However, its zener voltage should be low enough so that the zener diode conducts if the supply pin begins to rise above the safe operating supply voltage level.
