The TPH2501/3, THP2502, TPH2504 are single, dual, quad low power, high speed unity gain stable rail-to-rail input/output operational amplifiers. On only 6.5mA of supply current they feature an impressive 250MHz gain-bandwidth product, 180V/μs slew rate and a low 6.5nV/√Hz of input-referred noise, TPH2503 offers a shutdown current of only 1μA. 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. 

The TPH2501 family maintains high efficiency performance from supply voltage levels of 2.5V to 5.5V and is fully specified at supplies of 2.7V and 5.0V. The TPH2501 family can be used as a plug-in replacement for many commercially available op amps to reduce power or to improve I/O range and performance. The TPH2501 is single channel version available in 5-pin SOT23 package. The TPH2502 is dual channel version available in 8-pin SOP and MSOP packages. The TPH2503 is in 6-pin SOT23 package with shutdown function. The TPH2504 is quad channel version available in 14-pin SOP and TSSOP packages.
