LTC6255/LTC6256/LTC6257 6.5MHz, 65A Power Efficient Rail-to-Rail I/O Op Amps Fe A Description n Gain Bandwidth Product: 6.5MHz The LTC 6255/LTC6256/LTC6257 are single/dual/quad n 3dB Bandwidth (A = +1): 4.5MHz operational amplifiers with low noise, low power, low V n Low Quiescent Current: 65A supply voltage, and rail-to-rail inputs and outputs. They n C-Load Op Amp Drives all Capacitive Loads are unity gain stable with or without capacitive loads. n Offset Voltage: 350V Maximum They feature 6.5MHz gain-bandwidth product, 1.8V/s n Rail-to-Rail Input and Output slew rate while consuming only 65A of supply current n Supply Voltage Range: 1.8V to 5.25V per amplifier operating on supply voltages ranging from n Input Bias Current: 50nA Maximum 1.8V to 5.25V. The combination of low supply current, n CMRR/PSRR: 100dB/100dB low supply voltage, high gain bandwidth product and low n Shutdown Current: 7A Maximum noise makes the LTC6255 family unique among rail-to-rail n Operating Temperature Range: 40C to 125C input/output op amps with similar supply current. These n Single in 6-Lead TSOT-23, 2mm 2mm DFN Packages operational amplifiers are ideal for low power and low n Dual in 8-Lead MS8, MS10, TS0T-23, 2mm 2mm noise applications. DFN, 2mm 2mm Thin DFN Packages For applications that require power-down, the LTC6255 n Quad in MS16 Package and LTC6256 in S6 and MS10 packages offer shutdown which reduces the current consumption to 7A maximum. Applic A The LTC6255 family can be used as plug-in replacements n Micropower Active Filters for many commercially available op amps to reduce power n Portable Instrumentation and improve input/output range and performance. n Battery or Solar Powered Systems L, LT, LTC, LTM, Linear Technology and the Linear logo are registered trademarks and Over-The-Top and C-Load are trademarks of Linear Technology Corporation.
