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
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.
