The LTC1278 is a 1.6µs, 500ksps, sampling 12-bit A/D converter that draws only 75mW from a single 5V or ±5V supplies. This easy-to-use device comes complete with a 200ns 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 made even more attractive by a 8.5mW power-down feature. Instant wake-up from shutdown allows the converter to be powered down even during brief inactive periods.

The LTC1278 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 1.6µs conversion time. The clock automatically synchronizes to each sample command, eliminating problems with asynchronous clock noise found in competitive devices. A separate convert start input and a data ready signal (BUSY) ease connections to FIFOs, DSPs and microprocessors.
