AD4002BRMZ

AD4002 high accuracy, high speed, low power, 18bit easy drive, precision successive approximation register (SAR) analog to digital converter (ADC) that operate from a single power supply, VDD. 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 need for dedicated ADC driver. Easy Drive broadens the range of companion circuitry that is capable of driving these ADCs. This ADC features greatly reduced input kickback,First conversion accurate, no latency or pipeline delay, input span compression for single-supply operation, fast conversion allows low SPI clock rates and input overvoltage clamp protection sinks up to 50mA. Typical applications include automated test equipment, machine automation, medical equipment, battery-powered equipment, precision data acquisition systems, instrumentation and control systems.
