3.5.10 function introduction to TLV272
1. DESCRIPTION
The TLV27x takes the minimum operating supply voltage down to 2.7 V over the extended industrial
temperature range while adding the rail-to-rail output swing feature. This makes it an ideal alternative to the
TLC27x family for applications where rail-to-rail output swings are essential. The TLV27x also provides 3-MHz
bandwidth from only 550µA.
Like the TLC27x, the TLV27x is fully specified for 5-V and ±5-V supplies. The maximum recommended
supply voltage is 16 V, which allows the devices to be operated from a variety of rechargeable cells (±8 V
supplies down to ±1.35 V).
The CMOS inputs enable use in high-impedance sensor interfaces, with the lower voltage operation
making an attractive alternative for the TLC27x in battery-powered applications.
All members are available in PDIP and SOIC with the singles in the small SOT-23 package, duals in the
MSOP, and quads in the TSSOP package.
The 2.7-V operation makes it compatible with Li-Ion powered systems and the operating supply voltage
range of many micro power microcontrollers available today including TI’s MSP430.
