description
The TLV245x is a family of rail-to-rail input/output operational amplifiers that sets a new performance point for
supply current and ac performance. These devices consume a mere 23 µA/channel while offering 220 kHz of
gain-bandwidth product, much higher than competitive devices with similar supply current levels. Along with
increased ac performance, the amplifier provides high output drive capability, solving a major shortcoming of
older micropower rail-to-rail input/output operational amplifiers. The TLV245x can swing to within 250 mV of
each supply rail while driving a 2.5-mA load. Both the inputs and outputs swing rail-to-rail for increased dynamic
range in low-voltage applications. This performance makes the TLV245x family ideal for portable medical
equipment, patient monitoring systems, and data acquisition circuits.
