Description

The LTC®6253-7 is a dual high speed, low power, rail-torail input/output operational amplifier. On only 3.5mA of supply current, it features a 2GHz gain-bandwidth product, 500V/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 LTC6253-7 ideal for lower supply voltage, high speed signal conditioning systems. The device is stable for closed loop noise gains of 7 or higher.

The LTC6253-7 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 LTC6253-7 offers a shutdown pin which disables the amplifier and reduces current consumption to 42μA.

The LTC6253-7 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.
