AD1674KR

Data acquisition systems have a variety of purposes, ranging from analog-to-digital conversion to data storage, analysis, and display. In this article, we’ll discuss the application field and working principle of one such data acquisition system, the AD1674KR. The AD1674KR is an analog-to-digital (ADC) converter specifically designed for low-power, low-voltage, and high-resolution operation in high-speed systems.

The AD1674KR is a 12-bit dual-channel ADC providing high resolution, low power operation. Its small package size and power-saving features help to make it a suitable device for use in a variety of portable and battery-powered applications. It can be used in medical, telecommunications, navigation, and other high-precision data acquisition applications.

The AD1674KR utilizes a unique pipelined architecture featuring a two-step conversion process. The pipelined architecture enables fast conversion, while the two-step conversion allows it to achieve a low power dissipation. The AD1674KR also offers a wide input range of up to 1V, with a 2x over-range detection. This feature helps protect the ADC from erroneous inputs, providing immunity to DC and AC offsets.

The AD1674KR is also designed to provide low power dissipation. It features a low quiescent current of 2.5mV combined with a high start-up current of 160μA. The device also includes two low-power sleep modes: Sleep1 (LP1), and Sleep2 (LP2). When the device enters one of these sleep modes, the total power consumption is reduced to less than 10μA.

In addition to its low power design, the AD1674KR provides the user with a user-friendly programmable interface. The interface allows the user to configure the device for optimal performance by selecting the input range, clock frequency, MUX configuration, and sampling mode. The device also features a flexible control logic with multiple interrupt modes, as well as power-on reset.

The AD1674KR also features a number of features designed to improve overall system performance. Its high-performance data-formatter allows the user to store incoming data directly in memory. Its built-in calibration system helps to ensure a high degree of accuracy, while its power-down mode allows the user to conserve energy when the device is not in use. Finally, its low-jitter PLL clock drivers ensure high-speed and accurate timing.

In conclusion, the AD1674KR is a high-performance, low-power ADC specifically designed for use in high-precision data acquisition applications. Its unique pipelined architecture and two-step conversion process enable fast conversion, while its power-saving sleep modes and low quiescent current help to make it a suitable device for use in portable and battery-powered applications. Its versatile control logic, user-friendly programmable interface, and high-performance data-formatter make it an ideal ADC for a variety of applications.
