Product Summary

The LTC1400CS8 is a complete 400ksps, 12-bit A/D converter which draws only 75mW from a 5V or ± 5V supplies.This easy-to-use device comes complete with a 200ns sample-and-hold and a precision reference. Unipolar and bipolar conversion modes add to the flexibility of the ADC. The LTC1400 has two power saving modes: Nap and Sleep. In Nap mode, it consumes only 6mW of power and can wake up and convert immediately. In the Sleep mode, it consumes 30μW of power typically. Upon power-up from Sleep mode, a reference ready (REFRDY) signal is available in the serial data word to indicate that the reference has settled and the chip is ready to convert.
