LTC6261/LTC6262/LTC6263 30MHz, 240A Power Efficient Rail-to-Rail I/O Op Amps 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. n Micropower Active Filters L, LT, LTC, LTM, Linear Technology and the Linear logo are registered trademarks and n Portable Instrumentation Over-The-Top and C-Load are trademarks of Analog Devices, Inc.
