TLV2471A

单路低功耗轨至轨输入/输出运算放大器

The TLV247x is a family of CMOS rail-to-rail input/ outputoperational amplifiers that establishes a new performance point for supply current versus ac performance. These devices consume just 600µA/channel while offering 2.8MHz of gain-bandwidth product. Along with increased ac performance, the amplifier provides high output drive capability, solving a major shortcoming of older micropower operational amplifiers. The TLV247x can swing to within 180mV of each supply rail while driving a 10mA load. For non-RRO applications, the TLV247x can supply ±35mA at 500mV off the rail. Both the inputs and outputs swing rail-to-rail for increased dynamic range in low-voltage applications. This performance makes the TLV247x family ideal for sensor interface, portable medical equipment, and other data acquisition circuits.
