Fe A Description
n
Gain Bandwidth Product: 30MHz The LTC 6261/LTC6262/LTC6263 are single/dual/quad op-
n
Low Quiescent Current: 240A erational amplifiers with low noise, low power, low supply
n
Op Amp Drives up to 1nF Capacitive Loads voltage, and rail-to-rail inputs and outputs. They are unity
n
Offset Voltage: 400V Maximum gain stable with capacitive loads up to 1nF. They feature
n
Rail-to-Rail Input and Output 30MHz gain-bandwidth product, 7V/s slew rate while
n
Supply Voltage Range: 1.8V to 5.25V consuming only 240A of supply current per amplifier
n
Input Bias Current: 100nA Maximum operating on supply voltages ranging from 1.8V to 5.25V.
n
CMRR/PSRR: 100dB/95dB The combination of low supply current, low supply voltage,
n
Shutdown Current: 10A Maximum high gain bandwidth product and low noise makes the
n
Operating Temperature Range: 40C to 125C LTC6261 family unique among rail-to-rail input/output op
n
Single in 6-Lead TSOT-23, 2mm 2mm DFN amps with similar supply current. These operational ampli-
Packages fiers are ideal for low power and low noise applications.
n
Dual in 8-Lead MS8, MS10, TS0T-23, 2mm 2mm
For applications that require power-down, the LTC6261
DFN Packages
and LTC6262 in MSOP-10 offer shutdown which reduces
n
Quad in MS16 Package
the current consumption to 10A maximum.
The LTC6261 family can be used as plug-in replacements
Applic A
for many commercially available op amps to reduce power
and improve input/output range and performance.
