The LTC1417 is a low power, 400ksps, 14-bit A/D converter. This versatile device can operate from a single 5V or ±5V supplies. An on-board high performance sample-and-hold, a precision reference and internal trimming minimize external circuitry requirements. The low 20mW power dissipation is made even more attractive with two user-selectable power shutdown modes.

The LTC1417 converts 0V to 4.096V unipolar inputs when using a 5V supply and ±2.048V bipolar inputs when using ±5V supplies. DC specs include ±1.25LSB INL, ±1LSB DNL and no missing codes over temperature. Outstanding AC performance includes 81dB S/(N + D) and −95dB THD at a Nyquist input frequency of 200kHz.

The internal clock is trimmed for 2µs maximum conversion time. A separate convert start input and a data ready signal (BUSY) ease connections to FIFOs, DSPs and microprocessors.
