description

The TLV278x single supply operational amplifiers

provide rail-to-rail input and output capability. The

TLV278x takes the minimum operating supply

voltage down to 1.8 V over the extended industrial

temperature range (−40°C to 125°C) while adding

the rail-to-rail output swing feature. The TLV278x also provides 8 MHz bandwidth from only 650 µA of supply

current. The maximum recommended supply voltage is 3.6 V, which allows the devices to be operated from

(±1.8 V supplies down to ±0.9 V) two rechargeable cells.

The combination of wide bandwidth, low noise, and low distortion makes it ideal for high speed and high

resolution data converter applications.

All members are available in PDIP, SOIC, and the newer, smaller SOT-23 (singles), MSOP (duals), and TSSOP

(quads).

! ! SLOS245E − MARCH 2000 − 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 32).
