LTC6258 - 1.3MHz, 20μA Power Efficient Rail-to-Rail I/O Op Amps

The LTC®6258/LTC6259/LTC6260 are single/dual/quad operational amplifiers with low noise, low power, low supply voltage, and rail-to-rail inputs and outputs. They are unity gain stable with or without capacitive loads. They feature 1.3MHz gain-bandwidth product, 0.24V/μs slew rate while consuming only 20μA of supply current per amplifier operating on supply voltages ranging from 1.8V to 5.25V. The combination of low supply current, low supply voltage, high gain bandwidth product and low noise makes the LTC6258 family unique among rail-to-rail input/output op amps with similar supply current. These operational amplifiers are ideal for power efficient applications.

For applications that require power-down, the LTC6258 in 2mm × 2mm DFN and LTC6259 MS10 packages respectively offer shutdown which reduces the current consumption to 7μA maximum.

The LTC6258 family can be used as plug-in replacements for many commercially available op amps to reduce power and improve input/output range and performance.
