LTC1279 12-Bit, 600ksps Sampling A/D Converter with Shutdown
The LTC™1279 is a 1.4µs, 600ksps, sampling 12-bit A/D converter which draws only 60mW from a single 5V or ±5V supplies. This easy-to-use device comes complete witha 160ns sample-and-hold, a precision reference and an internally trimmed clock. Unipolar and bipolar conversion modes add to the flexibility of the ADC. The low power dissipation is reduced even more, drawing only 8.5mW in power shutdown mode. Instant wake-up from power shutdown allows the converter to be powered down even during brief inactive periods. The LTC1279 converts 0V to 5V unipolar inputs from a single 5V supply and ±2.5V bipolar inputs from ±5V supplies. Maximum DC specs include ±1LSB INL and ±1LSB DNL. Outstanding guaranteed AC performance includes 70dB S/(N D) and 78dB THD at the input frequency of 100kHz over temperature. The internal clock is trimmed for 1.4µs conversion time. The clock automatically synchronizes to each sample command,eliminating problems with asynchronous clock noisefound in competitive devices. A separate conversion start input and a data-ready signal (BUSY) ease connections to FIFOs, DSPs and microprocessors
