Working Principle

The AD7581LNZ employs the latest in successive approximation register (SAR) architecture for ultimate accuracy and power efficiency. The entire ADC architecture is digital, making it reliable and relatively easy to interface to most microcontrollers. When the start bit is set, the ADC starts to convert the analog input to digital data. The SAR control logic, then samples and encodes the input analog data in a digital form. The conversion result is encoded in two’s complement binary format and combined with the high-speed clock, which ensures faster conversion cycles, better linearity, and higher accuracy.

The ADC also features an on-chip voltage reference, which is programmable and is used to provide the reference voltage for the input signal. The voltage range of the on-chip reference can be varied to suit different applications and provides improved performance compared to an external reference.

The AD7581LNZ is also available in several package options. These package options provide options for surface mount, plastic leaded chip carrier (PLCC), and quad flat compatible packages, making it easy to integrate the ADC into existing systems.
