NCT6112D

The NCT6112D is part of an integrated series of analog to digital converters (ADCs) manufactured by Nuvoton Technologies Ltd. This device is highly integrated with features such as a low power wide input range 125MS/s sampling rate, autocalibration, and a variety of on-chip averaging features. It is ideal for applications such as digital video and imaging, as well as various industrial analog-to-digital measurement applications.

The NCT6112D is an example of a sigma-delta ADC. It uses a delta-sigma conversion architecture that provides high resolution and a wide dynamic range of ±3V. The ADC boasts 12-bits of resolution and a 4 simultaneous low voltage differential inputs. It supports S/HAP Programmable Analog PGA and a selectable power savings modes.

The working principle of the NCT6112D is based on the delta sigma architecture. This architecture relies on oversampling, meaning it samples the analog signal more than what would generally be needed for the desired result. By doing this, more bits of information can be extracted from the signal, resulting in greater resolution and accuracy.

The oversampling generates digital data, which is then filtered and compressed by the digital signal processor. The result is a serial output port, providing the 12-bits of resolution and 4x sampling rate. The overall conversion time is typically 10 to 20 microseconds.

The NCT6112D is suitable for a wide range of applications including industrial temperature measurement, pressure sensing and optical measurement, process control and motor/servo control. It is also used in medical instrumentation, digital video and imaging and several other applications. Its high resolution and wide dynamic range makes it perfectly suitable for these types of projects.

The wide input range, low power consumption and high performance make the NCT6112D an excellent choice for signal conditioning, signal acquisition and data conversion applications that require low noise, high accuracy and high data throughput. The device is RoHS compliant, is available in both a 1.8V and 3.3V version and is protected against transiebnt voltages up to ±50V.

Nuvoton\'s highly integrated NCT6112D is a prime example of a specialised ADC that combines low power consumption, high performance, wide dynamic range and a fast sampling rate in one device, perfect for use in a variety of demanding analog-to-digital conversion applications.
