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.

µ SLOS270D − MARCH 2001 − REVISED JANUARY 2005 APPLICATION INFORMATION rail-to-rail input operation The TLV237x input stage consists of two differential transistor pairs, NMOS and PMOS, that operate together to achieve rail-to-rail input operation. The transition point between these two pairs can be seen in Figure 1, Figure 2, and Figure 3 for a 2.7-V, 5-V, and 15-V supply.

µ SLOS270D − MARCH 2001 − REVISED JANUARY 2005 APPLICATION INFORMATION general configurations When receiving low-level signals, limiting the bandwidth of the incoming signals into the system is often required. The simplest way to accomplish this is to place an RC filter at the noninverting terminal of the amplifier (see Figure 35).
