Working Principle

The ADC081C021CIMM/NOPB converts an analogue voltage signal into a digital code. The device has an input range of 0V to VREF. The input limits of the device are typically 0V (brick wall) to VREF+0.3V. The device also includes an integrated ground reference to ensure accurate digital code output.

The ADC081C021CIMM/NOPB features an integrated internal reference. The device features a self-calibrated voltage reference which allows for temperature-stable, accurate conversions with no external components required. The internal reference is accurate over temperature with a typical accuracy of ±0.51%.

The ADC081C021CIMM/NOPB operates in either single shot or continuous conversion mode. In single shot mode, the device will convert one sample and then enter a low power mode. In continuous conversion mode, the device will continuously perform conversions until the user issues a stop command.

The converter includes an 8-bit SAR logic which provides high speed and low power consumption. The ADC081C021CIMM/NOPB uses CMOS technology and has a typical supply current of 400uA. The device has an adjustable conversion rate which can be programmed with a single logic pin.

The ADC081C021CIMM/NOPB also includes an integrated analog multiplexer which allows the user to select between two or four input channels. The multiplexer has a maximum switch resistance of 10kΩ and can handle input voltages up to VREF+0.3V. The device also features a low voltage detection function which alerts the user when the input voltage falls below a certain voltage threshold.

The ADC081C021CIMM/NOPB also features an integrated internal clock which can run at frequencies up to 3.6MHz. The internal clock has an adjustable duty cycle and can be controlled with a single logic pin. The device also has an integrated fault detection and recovery function which allows the user to flag invalid data.
