DESCRIPTION
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 with a 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.
