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

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

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.
