Analog to Digital Converters (ADC) provide generalized solutions to challenging engineering problems. The ADC 11DV200CISQE/NOPB is one such example and is designed to meet specific application requirements of data acquisition, image processing, and industrial automation. This section will provide an overview of the ADC 11DV200CISQE/NOPB’s application field and working principle.

Application Field

The ADC 11DV200CISQE/NOPB is a high-performance, low power, integrated analog-to-digital converter (ADC). It is designed for use in applications such as data acquisition for industrial and consumer appliances, image processing, and industrial automation.

The ADC 11DV200CISQE/NOPB provides 12-bit resolution and a maximum sample rate of 1.2MSPS (millions of samples per second). The converter operates on a single supply voltage from +2.375V to +3.465V, and it is capable of processing both single-ended and differential input signals. The ADC11DV200CISQE/NOPB is also equipped with an on-chip reference voltage, as well as an on-chip programmable gain amplifier (PGA) and an analog low-pass filter (LPF). Additionally, it is packaged in a small, low-pin-count, 32-lead LQFP.

The ADC 11DV200CISQE/NOPB is well-suited for portable and stationary data acquisition applications, due to its low power consumption and small form factor. It is also beneficial for applications that require parameter calibration, such as image processing or industrial automation.

Working Principle

The ADC 11DV200CISQE/NOPB follows a standard three-stage architecture for analog-to-digital conversion. The first stage is an amplifier and an analog low-pass filter that together amplify and filter the input signal. The second stage is a sample-and-hold circuit that captures and holds the amplified and filtered signal for conversion. The last stage is a 12-bit successive approximation register (SAR) that performs the digital conversion.

The ADC 11DV200CISQE/NOPB utilizes a high-speed SAR architecture which enables a maximum sample rate of 1.2MSPS. This architecture is optimized for low power consumption, allowing for a low power supply voltage from +2.375V to +3.465V. In addition, on-chip features such as PGA and LPF reduce overall system cost by reducing the need for external components.

The ADC 11DV200CISQE/NOPB also supports up to four different modes of operation depending on the application. These modes are single-ended output, differential output, differential offset, and differential gain. These modes are selected via the serial port interface (SPI), which is used to configure the device and retrieve the converted data.

The ADC 11DV200CISQE/NOPB provides an accurate, low-power solution for data acquisition applications that require parameter calibration, such as image processing or industrial automation.
