Both devices exhibit rail-to-rail output performance for increased dynamic range vs HIGH-LEVEL OUTPUT CURRENT 3 VDD = 3 V VOH − High-Level Output Voltage − V in single- or split-supply applications. The 2.5 TLV225x family consumes only 34 µA of supply current per channel. This micropower operation TA = − 40°C makes them good choices for battery-powered 2 applications. This family is fully characterized at TA = 25°C 3 V and 5 V and is optimized for low-voltage 1.5 applications. The noise performance has been dramatically improved over previous generations TA = 85°C of CMOS amplifiers. The TLV225x has a noise 1 level of 19 nV/√Hz at 1...
