description
The TLV237x single supply operational amplifiers provide rail-to-rail input and output capability. The TLV237x
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. The TLV237x also provides 3-MHz bandwidth from only 550 µA. The
maximum recommended supply voltage is 16 V, which allows the devices to be operated from (±8 V supplies
down to ±1.35 V) a variety of rechargeable cells.
The CMOS inputs enable use in high-impedance sensor interfaces, with the lower voltage operation making
an ideal alternative for the TLC227x in battery-powered applications. The rail-to-rail input stage further
increases its versatility. The TLV237x is the seventh member of a rapidly growing number of RRIO products
available from TI, and it is the first to allow operation up to 16-V rails with good ac performance.
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 the TLV237x compatible with Li-Ion powered systems and the operating supply
voltage range of many micro-power microcontrollers available today including TI’s MSP430.
