Product Summary
The LTC1400CS8#TR is a complete 400ksps, 12-bit A/D converter which draws only 75mW from 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 LTC1400CS8#TR 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. The applications of the LTC1400CS8#TR include High Speed Data Acquisition, Digital Signal Processing, Multiplexed Data Acquisition Systems, Audio and Telecom Processing, Digital Radio, Spectrum Analysis, Low Power and Battery-Operated Systems, Handheld or Portable Instruments.
