• CMOS Rail-To-Rail Input/Output The TLV247x is a family of CMOS rail-to-rail input/

• Input Bias Current: 2.5pA output operational amplifiers that establishes a new

performance point for supply current versus ac

• Low Supply Current: 600μA/Channel

performance. These devices consume just

• Ultra-Low Power Shutdown Mode:

600μA/channel while offering 2.8MHz of

IDD(SHDN): 350nA/ch at 3V gain-bandwidth product. Along with increased ac

IDD(SHDN): 1000nA/ch at 5V performance, the amplifier provides high output drive

• Gain-Bandwidth Product: 2.8MHz capability, solving a major shortcoming of older

micropower operational amplifiers. The TLV247x can

• High Output Drive Capability:

swing to within 180mV of each supply rail while

– ±10mA at 180mV driving a 10mA load. For non-RRO applications, the

– ±35mA at 500mV TLV247x can supply ±35mA at 500mV off the rail.

Both the inputs and outputs swing rail-to-rail for

• Input Offset Voltage: 250μV (typ)

increased dynamic range in low-voltage applications.

• Supply Voltage Range: 2.7V to 6V This performance makes the TLV247x family ideal

• Ultra-Small Packaging for sensor interface, portable medical equipment,

and other data acquisition circuits.
