description
The TLV278x single supply operational amplifiers

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

voltage down to 1.8 V over the extended industrial
f − Frequency − Hz
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).
