2.3.3 TLVx172

The TLV172 operational amplifier provides high overall performance, making these devices designed for many general-purpose applications. The excellent offset drift of only 1 μV/°C provides excellent stability over the entire temperature range. In addition, the device offers very good overall performance with high CMRR, PSRR, and AOL.
