Analog-to-digital converters (ADCs) are a type of data acquisition device used to convert analog signals into digital values capable of being read and displayed by a computer, smartphone, or other digital device. The ADC12D1000CIUT/NOPB is an ADC specifically designed to maximize speed and minimize power consumption in applications requiring moderate resolution and low sampling rates. In this article, we will outline the application field and working principle of the ADC12D1000CIUT/NOPB.

Application Field:

The ADC12D1000CIUT/NOPB is a 12-bit A/D Conversion System with integrated Voltage Reference and 1.2 MHz converting rate. Its main features include low-power consumption, wherein 1.5 mW power consumption is achieved in typical single-channel, single-ended A/D conversion applications; 5.5 V single supply operation; comprehensive on-chip system building blocks; a wide supply voltage range from 2.0 V to 6.0 V; true rail-to-rail input capabilities; adjustable serial data output formats of 16-, 20-, or 24-bit words; multiple on-chip addressing capabilities for multi-channeled applications; and a maximum sampling rate of 1.2 MHz in pseudo-differential uni-polar input mode. The ADC12D1000CIUT/NOPB is ideally suited for low-power, high speed, moderate resolution and single-ended applications.

Applications for the ADC12D1000CIUT/NOPB include low-power sensors, shelf level, near-field and remote sensing, medical instrumentation, power instrumentation, audio, industrial motor control and home automation. The device is also ideal for smart wearables, Internet of Things (IoT) devices, and embedded systems.

Working Principle:

The ADC12D1000CIUT/NOPB is a high-speed, low-power 12-bit analog-to-digital converter with an integrated voltage reference. It features a 10-bit programmable gain amplifier (PGA) which has a gain range of 8 to 1024. The device also has an on-chip temperature measurement circuit which can be used for temperature sensing applications. It also includes a 10-bit parallel output port with 16-, 20-, or 24-bit data words.

The ADC12D1000CIUT/NOPB converts an analog input signal into an 12-bit digital representation at the sampling rate of 1.2 MHz. The two main conversion steps of the ADC—Analog-to-Digital (A/D) conversion and conversion to digital data—are performed using a successive-approximation A/D converter (SAR) and a track-and-hold circuit with a high-speed digital-to-analog converter (DAC) followed by a comparator. The SAR algorithm is implemented to measure the analog input and the digital-to-analog converter (DAC) is used to compare the measured input with the output of the DAC. The conversion result is then written to a digital result register.

The ADC12D1000CIUT/NOPB also includes several alarm protection features, including digital and analog input level monitoring, digital output blanking, output slew rate limiting, and power-on reset. In addition, the device has an on-chip voltage reference and internal oscillator, and can be programmed to use either single-sample or multi-sample conversions. The on-chip DC-Offset calibration feature allows the device to be integrated into a variety of signal conditioning systems, such as signal filters, and amplifier circuits.

The ADC12D1000CIUT/NOPB is a low-cost, low-power, high-performance A/D converter with a wide range of applications. It is designed to be used in low-power measurements, allowing it to be used in a variety of applications such as industrial motor control, medical instrumentation, power instrumentation, audio transcriptions, low-power sensors, and home automation.
