The LT6203X is a dual low noise, rail-to-rail input and output unity gain stable op amp that features 1.9nV/√Hz noise voltage and draws only 2.5mA of supply current per amplifier. These amplifiers combine very low noise and supply current with a 100MHz gain bandwidth product, a 25V/µs slew rate, and are optimized for low supply signal conditioning systems.

These amplifiers maintain their performance for supplies from 2.5V to 12.6V and are specified at 3V, 5V and ±5V supplies. Harmonic distortion is less than –80dBc at 1MHz making these amplifiers suitable in low power data acquisition systems.

These devices can be used as plug-in replacements for many op amps to improve input/output range and noise performance.

The LT6203X is a member or a growing series of high temperature qualified products offered by Analog Devices.

The LT6203X comes in an 8-pin SO package with standard dual op amp pinout. The LT6203X is also available as dice.
