LTC6261/LTC6262/LTC6263

30MHz, 240µA Power

Efficient Rail-to-Rail I/O

Op Amps

Description

The

LTC

®

6261/LTC6262/LTC6263

are single/dual/quad op-

erational amplifiers with low noise, low power, low supply

voltage, and rail-to-rail inputs and outputs. They are unity

gain stable with capacitive loads up to 1nF They feature

.

30MHz gain-bandwidth product, 7V/µs slew rate while

consuming only 240µA of supply current per amplifier

operating on supply voltages ranging from 1.8V to 5.25V.

The combination of low supply current, low supply voltage,

high gain bandwidth product and low noise makes the

LTC6261 family unique among rail-to-rail input/output op

amps with similar supply current. These operational ampli-

fiers are ideal for low power and low noise applications.

For applications that require power-down, the LTC6261

and LTC6262 in MSOP-10 offer shutdown which reduces

the current consumption to 10µA maximum.

The LTC6261 family can be used as plug-in replacements

for many commercially available op amps to reduce power

and improve input/output range and performance.
