The AD7856ANZ is a high speed, low power 14-bit Analog-to-digital Converter (ADC) that operates from a single 5V power supply. The ADC powers up with a set of default conditions at which the time it can be operated as a read only ADC. The ADC contains self-calibration and system calibration options to ensure accurate operation over time and temperature and it has a number of power-down options for low power applications. It is capable of 285kHz throughput rate. The input track-and-hold acquires a signal in 500 ns and features a pseudo-differential sampling scheme. The converter voltage range is 0 to VREF with straight binary output coding. Input signal range is to the supply and the part is capable of converting full power signals to 10MHz. CMOS construction ensures low power dissipation of typically 60mW for normal operation and 5.1mW in power-down mode at 10kSPS throughput rate.

• Self and system calibration with auto calibration on power-up
• Eight single-ended or four pseudo-differential inputs
• Automatic power-down after conversion
• Flexible serial interface - 8051/SPI™/QSPI™/µP compatible
