description
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 600
µA/channel
while offering 2.8 MHz 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 180 mV of each supply rail while driving a 10-mA load. For non-RRO applications,
the TLV247x can supply
±35
mA at 500 mV 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.
