Data Acquisition - Analog to Digital Converters (ADC) can be broadly categorized by their interface, speed and resolution. AD10242TZ/883B, a 12-bit, 250-kSPS (kilo samples per second) family of low-power, low-cost analog-to-digital (A/D) converters is unique because it combines a high resolution, low noise, low power consumption, and fast sampling rate features. AD10242TZ/883B can provide high precision data acquisition of analog signals and deliver digital sampled data output in real time.

The key feature of the device is its high accuracy (only 3-bit ENOB, while providing a maximum sample rate of up to 250 kSPS), low power consumption (ranging from only 55mW to 70mW), and a low noise, low-distortion and low-jitter performance. These features make the device ideal for use in a wide range of industrial, automotive, laboratory and consumer applications, such as medical instrumentation, industrial control, and mobile device monitoring.

AD10242TZ/883B is equipped with an integrated on-chip 4x over-sampling analog front end, and a multi-clock frequency range from 2.9 MHz to 75 MHz. Working voltage range is from 1.2V to 3.6V. The analog-to-digital conversion is performed by successive approximation register (SAR) methods with 12-bit resolution. The device features a wide dynamic range with low-distortion characteristics. this outstanding performance make this device ideal for a wide range of applications including audio, video and images.

The ADC can receive an analog signal directly and convert it into a digital number that can be stored in memory or further processed by higher level systems. An analog to digital converter performs this process by repeatedly measuring the analog voltage applied at its input and converting it into a digital code. This is done through various stages of clock signals and comparator. The clock signal determines the speed of conversion while the two analog reference signals define the digital output range. The reference voltage is applied to a comparison circuit which changes its output value when it finds the reference voltage equal to the analog input voltage. The output of the comparator initiates a count cycle to generate a digital number.

AD10242TZ/883B features an auto-zeroing system that eliminates short-term gain errors. This device also features low internal timing jitter and low total harmonics distortion (THD). In addition, the device includes an on-chip voltage reference, eliminating the need for an off-chip reference voltage circuit. This device also supports an on-chip power down mode, resulting in a low power consumption. The device can also be adapted to various power supply applications.

The AD10242TZ/883B is highly flexible in terms of its application field and working principle. From medical instruments to consumer electronics, industrial control systems, automotive electronics, audio and video products, the device can be used in a wide range of applications. In addition, the device has a simple design and architecture, making it ideal for various embedded applications. Furthermore, the device can provide excellent performance while consuming low power.
