ANALOG DEVICES AD4006BRMZ Analogue to Digital Converter, 18 bit, 1 MSPS, Pseudo Differential

AD4006BRMZ is a high accuracy, high speed, low power, 18bit, easy drive, precision successive approximation register (SAR) analogue-to-digital converter (ADC) that operates from a single power supply, VDD. The reference voltage, VREF, is applied externally and can be set independently of the supply voltage. Easy drive features reduce both signal chain complexity and power consumption while enabling higher channel density. The reduced input current, particularly in high-Z mode, coupled with a long signal acquisition phase, eliminates the need for a dedicated ADC driver. Input span compression eliminates the need to provide a negative supply to the ADC driver amplifier while preserving access to the full ADC code range. It is used in applications such as automated test equipment, machine automation, medical equipment, battery-powered equipment, precision data acquisition systems, instrumentation, and control systems.
