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).
