LTC6252/LTC6253/LTC6254 720MHz, 3.5mA Power Efficient Rail-to-Rail I/O Op Amps FEATURES DESCRIPTION n Gain Bandwidth Product: 720MHz The LTC 6252/LTC6253/LTC6254 are single/dual/quad low n 3dB Frequency (A = 1): 400MHz power, high speed unity gain stable rail-to-rail input/output V n Low Quiescent Current: 3.5mA Max operational amplifiers. On only 3.5mA of supply current n High Slew Rate: 280V/s they feature a 720MHz gain-bandwidth product, 280V/s n Input Common Mode Range Includes Both Rails slew rate and a low 2.75nV/Hz of input-referred noise. n Output Swings Rail-to-Rail The combination of high bandwidth, high slew rate, low n Low Broadband Voltage Noise: 2.75nV/Hz power consumption and low broadband noise makes the n Power-Down Mode: 42A LTC6252 family 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: 350V Max The LTC6252 family maintains high efficiency performance n Large Output Current: 90mA from supply voltage levels of 2.5V to 5.25V and is fully n CMRR: 105dB specified at supplies of 2.7V and 5.0V. n Open Loop Gain: 60V/mV n For applications that require power-down, the LTC6252 and Operating Temperature Range: 40C to 125C n the LTC6253 in MS10 offer a shutdown pin which disables Single in 6-Pin TSOT-23 n the amplifier and reduces current consumption to 42A. Dual in MS8, 2mm 2mm DFN, 8-Pin TS0T-23, MS10 n Quad in MS16 The LTC6252 family can be used as a plug-in replacement for many commercially available op amps to reduce power APPLICATIONS or to improve input/output range and performance. n Low Voltage, High Frequency Signal Processing L, LT, LTC, LTM, Linear Technology and the Linear logo are registered trademarks of Linear Technology Corporation.
