On only 1mA of supply current they feature an impressive 180MHz gain-bandwidth product, 90V/μs slew rate and a low 4.2nV/√Hz of input-referred noise. The combination of high bandwidth, high slew rate, low power consumption and low broadband noise makes the LTC6246/LTC6247/LTC6248 unique among rail-to-rail input/output op amps with similar supply currents. The LTC6246/LTC6247/LTC6248 are ideal for lower supply voltage high speed signal conditioning systems. The LTC6246/LTC6247/LTC6248 maintain high efficiency performance from supply voltage levels of 2.5V to 5.25V and are fully specified at supplies of 2.7V and 5.0V. For applications that require power-down, the LTC6246 and the LTC6247 in MS10 offer a shutdown pin which disables the amplifier and reduces current consumption to 42μA. The LTC6246/LTC6247/LTC6248 can be used as plug-in replacements for many commercially available op amps to reduce power or to improve input/output range and performance.
