TLV2455IPW RRIO operational amplifier with shutdown

　　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 23µA/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.

 

　　Three members of the family(TLV2450/3/5)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 16 nA/channel.The family is fully specified at 3 V and 5 V 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 TLV2450 offers an amplifier with shutdown functionality all in a 6-pin SOT23 package,making it perfect for high density circuits.
