The AD7874BR is an integrated circuit (IC) component manufactured by Analog Devices Inc. It is a versatile, high-performance, 12-bit analog-to-digital converter (ADC) designed for various precision measurement applications. The device offers exceptional accuracy, low power consumption, and a range of advanced features that make it suitable for a wide range of industrial and instrumentation systems.
One of the key features of the AD7874BR is its four-channel simultaneous sampling capability. It includes four independent ADCs, enabling the device to capture analog signals from multiple input channels simultaneously. This simultaneous sampling feature is particularly beneficial in applications that require precise measurement of multiple signals in parallel.
The ADCs in the AD7874BR exhibit a conversion rate of up to 100 kilosamples per second (ksps). This high-speed conversion allows for real-time measurement and provides rapid updates of the input signal values. The device also incorporates a successive-approximation architecture, which enhances accuracy and minimizes noise and distortion.
An important aspect of the AD7874BR is its excellent analog performance. It boasts a total unadjusted error (TUE) of ±0.5 LSB and a differential non-linearity (DNL) specification of ±1 LSB, ensuring accuracy and precision in measurement. Furthermore, the device offers a wide input voltage range, allowing it to operate with signals spanning both single-ended and differential inputs
