New single/dual/quad rail to rail SiGe operational amplifiers from Linear tech

Linear Technology has launched the LTC6252/3/4 and LTC6255/6/7 single/dual/quad rail-to-rail SiGe operational amplifiers.

The LTC6252/3/4 provides 720MHz gain-bandwidth product and 280V/us slew rate while consuming 3.3mA supply current.
The LTC6255/6/7 provides 6.5MHz gain-bandwidth product and 1.8V/us slew rate, consuming 65uA supply current.

These parts join the previously released 180MHz gain-bandwidth Product 1mA supply current LTC6246/7/8 to provide a family of high efficiency op amps suitable for a wide array of applications.

The 720MHz, 3.3mA LTC6252/3/4 operates over supply voltages of 2.5V to 5.25V and has rail-to-rail inputs and outputs with fast output overdrive recovery.. These decices feature broadband noise of 2.75nV/rtHz and slew rate of 280V/us. The LTC6252/3/4 offers input offset voltage of 350uV max at room temperature, and 1mV max from -40C to 125C.

The 6.5MHz 65uA LTC6255/6/7 also features rail-to-rail inputs and outputs operating at supply voltages of 1.8V to 5.25. These op amps offer unity gain stable and can drive capacitive loads of up to 100nF. The LTC6255/6/7 offers input offset voltage is 350uV max at 25C and 700uV from -40C to 125C. These rail to rail Op amps are suggested for applications such as portable instrumentation, battery and solar powered systems, and automotive electronics.
