The LTC®6363 is a low power, low noise, fully differential op amp with rail-to-rail outputs optimized to drive low power SAR ADCs. The LTC6363 draws only 1.9mA supply current in active operation and features a shutdown mode which reduces the current consumption to 20μA (VS = 3V).
The amplifier may be configured to convert a single-ended input signal to a differential output signal or may be driven differentially. Low offset voltage and low input offset current make this amplifier suitable for use not only as an ADC driver but also earlier in the signal chain to provide filtering, gain or even attenuation by up to 10-to-1 to convert high voltage signals to levels suitable for low voltage ADCs.
The LTC6363 is available in 8-lead MSOP and 2mm × 3mm leadless DFN packages, and operates with guaranteed specifications over a –40°C to 125°C temperature range
