The LTC6252/LTC6253/LTC6254 are single/dual/quad low power, high speed unity gain stable rail-to-rail input/output operational amplifiers. On only 3.5mA of supply current they feature a 720MHz gain-bandwidth product, 280V/μs slew rate and a low 2.75nV/√Hz of input-referred noise. The combination of high bandwidth, high slew rate, low power consumption and low broadband noise makes the LTC6252 family unique among rail-to-rail input/output op amps with similar supply currents. They are ideal for lower supply voltage high speed signal conditioning systems. The LTC6252 family maintains high efficiency performance from supply voltage levels of 2.5V to 5.25V and is fully specified at supplies of 2.7V and 5.0V. For applications that require power-down, the LTC6252 and the LTC6253 in MS10 offer a shutdown pin which disables the amplifier and reduces current consumption to 42μA. The LTC6252 family can be used as a plug-in replacement for many commercially available op amps to reduce power or to improve input/output range and performance.
