1 / 24 page LTC6246/LTC6247/LTC6248 624678fa Typical applicaTion DescripTion 180MHz, 1mA Power Efficient Rail-to-Rail I/O Op Amps TheLTC®6246/LTC6247/LTC6248aresingle/dual/quadlow power,highspeedunitygainstablerail-to-railinput/output operational amplifiers. 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 these amplifiers 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. TheLTC6246familymaintainshighefficiencyperformance 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 LTC6246 and the LTC6247 in MS10 offer a shutdown pin which disables the amplifier and reduces current consumption to 42µA. The LTC6246 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.
