OPA2180 OPA4180 www.ti.com SBOS584C – NOVEMBER 2011 – REVISED DECEMBER 2012 APPLICATION INFORMATION The OPAx180 family of operational amplifiers combine precision offset and drift with excellent overall performance, making them ideal for many precision applications. The precision offset drift of only 0.085 µV/°C provides stability over the entire temperature range. In addition, the device offers excellent overall performance with high CMRR, PSRR, and AOL.

OPA2180 OPA4180 SBOS584C – NOVEMBER 2011 – REVISED DECEMBER 2012 www.ti.com GENERAL LAYOUT GUIDELINES For best operational performance of the device, good printed circuit board (PCB) layout practices are recommended. Low-loss, 0.1-µF bypass capacitors should be connected between each supply pin and ground, placed as close to the device as possible. A single bypass capacitor from V+ to ground is applicable to singlesupply applications.

OPA2180 OPA4180 www.ti.com SBOS584C – NOVEMBER 2011 – REVISED DECEMBER 2012 ELECTRICAL OVERSTRESS Designers often ask questions about the capability of an operational amplifier to withstand electrical overstress. These questions tend to focus on the device inputs, but may involve the supply voltage pins or even the output pin.
