TI TLV2475AIPWP

The TLV247x is a family of CMOS rail-to-rail input/ output operational 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. Three members of the family (TLV2470/3/5) offer a shutdown terminal for conserving battery life in portable applications. During shutdown, the outputs are placed in a high-impedance state and the amplifier consumes only 350nA/channel. The family is fully specified at 3V and 5V across an expanded industrial temperature range (-40°C to +125°C). The singles and duals are available in the SOT23 and MSOP packages, while the quads are available in TSSOP. The TLV2470 offers an amplifier with shutdown functionality all in a SOT23-6 package, making it perfect for high-density power-sensitive circuits.
