LTC6258/LTC6259/LTC6260 1.3MHz, 20A Power Efficient Rail-to-Rail I/O Op Amps FEATURES DESCRIPTION n Gain Bandwidth Product: 1.3MHz The LTC 6258/LTC6259/LTC6260 are single/dual/quad n Low Quiescent Current: 20A operational amplifiers with low noise, low power, low n C-Load Op Amp Drives all Capacitive Loads supply voltage, and rail-to-rail inputs and outputs. They n Offset Voltage: 400V Maximum are unity gain stable with or without capacitive loads. They n Rail-to-Rail Input and Output feature 1.3MHz gain-bandwidth product, 0.24V/s slew rate n Supply Voltage Range: 1.8V to 5.25V while consuming only 20A of supply current per amplifier n EMI Rejection Ratio: 45dB at 1GHz operating on supply voltages ranging from 1.8V to 5.25V. n Input Bias Current: 75nA Maximum The combination of low supply current, low supply volt- n CMRR/PSRR: 95dB/90dB age, high gain bandwidth product and low noise makes n Shutdown Current: 7A Maximum the LTC6258 family unique among rail-to-rail input/output n Operating Temperature Range: 40C to 125C op amps with similar supply current. These operational n Single in 6-Lead TSOT-23, 2mm 2mm DFN amplifiers are ideal for power efficient applications. Packages For applications that require power-down, the LTC6258 n Dual in 8-Lead MS8, MS10, TS0T-23, 2mm 2mm in 2mm 2mm DFN and LTC6259 MS10 packages DFN Packages respectively offer shutdown which reduces the current n Quad in MS16 Package consumption to 7A maximum. The LTC6258 family can be used as plug-in replacements APPLICATIONS for many commercially available op amps to reduce power n Micropower Active Filters and improve input/output range and performance. n Portable Instrumentation L, LT, LTC, LTM, Linear Technology and the Linear logo are registered trademarks and Over-The-Top and C-Load are trademarks of Analog Devices, Inc.
