LTC6246/LTC6247/LTC6248 180MHz, 1mA Power Efficient Rail-to-Rail I/O Op Amps FEATURES DESCRIPTION n Gain Bandwidth Product: 180MHz The LTC 6246/LTC6247/LTC6248 are single/dual/quad low n 3dB Frequency (A = 1): 120MHz power, high speed unity gain stable rail-to-rail input/output V n Low Quiescent Current: 1mA Max operational amplifiers. On only 1mA of supply current they n High Slew Rate: 90V/s feature an impressive 180MHz gain-bandwidth product, n Input Common Mode Range Includes Both Rails 90V/s slew rate and a low 4.2nV/Hz of input-referred n Output Swings Rail-to-Rail noise. The combination of high bandwidth, high slew rate, n Low Broadband Voltage Noise: 4.2nV/Hz low power consumption and low broadband noise makes n Power-Down Mode: 42A these amplifiers unique among rail-to-rail input/output op n Fast Output Recovery amps with similar supply currents. They are ideal for lower n Supply Voltage Range: 2.5V to 5.25V supply voltage high speed signal conditioning systems. n Input Offset Voltage: 0.5mV Max The LTC6246 family maintains high efficiency performance n Input Bias Current: 100nA from supply voltage levels of 2.5V to 5.25V and is fully n Large Output Current: 50mA specified at supplies of 2.7V and 5.0V. n CMRR: 110dB n For applications that require power-down, the LTC6246 and Open Loop Gain: 45V/mV n the LTC6247 in MS10 offer a shutdown pin which disables Operating Temperature Range: 40C to 125C n the amplifier and reduces current consumption to 42A. Single in 6-Lead TSOT-23 n Dual in MS8, 2mm 2mm DFN,TS0T-23, MS10 The LTC6246 family can be used as a plug-in replacement n Quad in MS16 for many commercially available op amps to reduce power or to improve input/output range and performance.
