Data output is selectable for 14-bit parallel or serial format. This versatile device can operate from a single 5V or ±5V supply. An onboard high performance sample-andhold, a precision reference and internal timing minimize external circuitry requirements. The low 15m W power dissipation is made even more attractive with two user selectable power shutdown modes. The LTC1418 converts 0V to 4.096V unipolar inputs from a single 5V supply and ±2.048V bipolar inputs from ±5V supplies. DC specs include ±1.25LSB INL, ±1LSB DNL and no missing codes over temperature. Outstanding AC performance includes 82d B S/(N + D) and 94d B THD at the Nyquist input frequency of 100k Hz. The flexible output format allows either parallel or serial I/O. The SPI/MICROWIRE patible serial I/O port can operate as either master or slave and can support clock frequencies from DC to 10MHz. A separate convert start input and a data ready signal (BUSY) allow easy control of conversion start and data transfer.
