<p>The AD7982BCPZ-RL is a 12-bit, low-power, single-channel, low-voltage analog-to-digital converter (ADC). This device is suitable for low power remote location applications that require low noise and low power consumption. The ADC can be operated from a single power supply, with support for both unipolar and bipolar input ranges. By leveraging the Charge Redistribution (CR) architecture, the device provides low power consumption and low noise, enabling simultaneous conversion and data readouts for extremely efficient operation.</p><p>The AD7982BCPZ-RL is available in a tiny 3 mm × 3 mm LFCSP_WQ package. The device operates from a single power supply of 3 V to 5.5 V, with a maximum single-ended input range of 0 V to VREF, with a 12-bit parallel output interface. The converter supports both unipolar (VREF to 0 V) and bipolar modes (-VREF to +VREF) input range with different codes. </p><p>The power efficiency of the AD7982BCPZ-RL enables remote location applications with low power requirement. The filter on the converter allows the user to select from two bandwidths—0.5 MHz and 8 MHz—allowing for application optimization.</p><p>The converters serial peripheral interface (SPI) allows efficient register reads and updates, allowing for low power operation by utilizing flexible programming features. The device is easy to use and program, and allows for easy integration into the system. The device can store the programmed register settings in its on-chip nonvolatile memory (NVM). </p><p>The AD7982BCPZ-RL\'s working principle is based on a successive approximation algorithm. This means that the device starts with an initial guess of the digital output code, then repeatedly refines its guess until it arrives at the correct code that is equivalent to the analog input voltage. This process is repeated in the span of a single conversion cycle, which is typically no more than a few microseconds. </p><p>The AD7982BCPZ-RL is suitable for various data acquisition and remote location applications, such as in automotive, industrial, medical, telecommunications and consumer electronics. Furthermore, its suitable for applications such as proximity sensing, piezo-sensors, strain gauges, pressure sensors, bridge sensors and thermocouples, as well as wireless monitoring, battery management and system monitoring. </p><p>The AD7982BCPZ-RL is an ideal solution for applications with low-power requirements. The device offers improved dynamic performance, low power consumption, good noise characteristics and easy integration. Additionally, the device offers a wide range of programming options, allowing for more versatility in system design. </p>
