The AD4000/AD4004/AD4008 are high accuracy, high speed, low power, 16-bit, precision successive approximation register (SAR) analog-to-digital converters (ADCs). These ADCs incorporate Easy Drive features, such as high-Z mode and an extended acquisition phase, which provide signal chain architectural flexibility by expanding the range of companion circuitry that can be paired with these ADCs.
Operating from a single power supply, VDD, these ADCs allow the reference voltage, VREF, to be applied externally and set independently of the supply voltage. With fast device throughput up to 2 MSPS, the AD4000/AD4004/AD4008 can accurately capture high-frequency signals and implement oversampling techniques to alleviate the challenges associated with antialias filter designs. Additionally, the power consumption of these ADCs scales linearly with throughput.
The AD4000/AD4004/AD4008 eliminate the need for a negative supply to the ADC driver amplifier by employing input span compression, while preserving access to the full ADC code range. Furthermore, the input overvoltage clamp protects the ADC inputs against overvoltage events, minimizing disturbances on the reference pin and eliminating the need for external protection diodes.
By reducing the serial peripheral interface (SPI) clock rate requirements, the AD4000/AD4004/AD4008 reduce digital input and output power consumption, broaden digital host options, and simplify the task of sending data across digital isolation. The SPI-compatible serial user interface supports 1.8 V, 2.5 V, 3.3 V, and 5 V logic by using the separate VIO logic supply.
