Data Acquisition - Analog to Digital Converters (ADC)

The TSA7887ARMZ-REEL is a 12-bit, four channel low-power, high-accuracy, low-noise Analog to Digital Converter (ADC) that offers a maximum sampling rate of 200 kHz. It features a configurable internal voltage reference, both single- and differential-ended input configurations, and versatile input ranges. The ADC also supports a configurable serial interface for communication between the host and IC.

Application Field

The TSA7887ARMZ-REEL ADC is ideal for a variety of applications in the consumer, home and industrial markets. This includes temperature and pressure monitoring, weight, current and voltage sensing, audio and video equipment, power supplies, and control applications. Additionally, due to its low power, high accuracy, and small footprint, the TSA7887ARMZ-REEL ADC is perfect for applications where low-power operation and high performance are critical.

Working Principle

The TSA7887ARMZ-REEL ADC is based on an analog comparator principle where an input voltage is compared to a reference voltage to produce a digital output representing the relative level of the two signals. The reference voltage is generated by an internal voltage reference. The comparator is then turned off and an integration cycle begins, during which the reference and input voltages are compared again, producing an output code that is proportional to the difference between the two signals. This process is repeated until the desired resolution is met. The integrated output code is then read at the serial port of the IC.

The TSA7887ARMZ-REEL ADC offers many features suitable for a wide range of applications. These features include a configurable single- and differential-ended input configuration, low-noise operation, high accuracy, selectable gain, and low power consumption. The onboard serial interface allows the user to communicate with the IC and to configure the device for the intended application.
