LTC1418 Low Power, 14-Bit, 200ksps ADC with Serial and Parallel I/O
The LTC®1418 is a low power, 200ksps, 14-bit A/D converter. 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-and-hold, a precision reference and internal timing minimize external circuitry requirements. The low 15mW 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 82dB S/(N + D) and 94dB THD at the Nyquist input frequency of 100kHz. The flexible output format allows either parallel or serial I/O. The SPI/MICROWIRE™ compatible 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
