The AD7492BRUZ-5 is a low-power, low-noise, 8-channel, successive approximation analog-to-digital converter (ADC) optimized for data acquisition systems requiring precise, low-noise measurements. This device is designed to convert analog input signals into 12-bit digital codes with excellent linearity and dynamic performance for many applications, including temperature measurement, strain gauge, weight scale, and process control systems. The AD7492BRUZ-5 also features a serial output port and a wide input range, making it ideal for low-power data logging and data processing systems.

Application field of AD7492BRUZ-5

The AD7492BRUZ-5 is a high-precision, low-power ADC that is well-suited for various data acquisition applications. The main application field of this device includes temperature, strain gauge, weight scale, and process control systems due to its wide input range, low power consumption, and excellent linearity and dynamic performance. This ADC can also be used for data logging and data processing systems such as remote monitoring, Condition Based Maintenance (CBM), and telemetry systems. Additionally, it is ideal for laboratory use, medical diagnostics, and industrial control systems due to its low power and high accuracy.

Working principle of AD7492BRUZ-5

The AD7492BRUZ-5 uses a successive approximation register (SAR) architecture in order to convert the analog input signal into a 12-bit digital code. In this architecture, a comparator is used to compare the analog input with a reference voltage. The result of this comparison is used to adjust the SAR’s digital coding until the analog signal is completely converted to the digital output. A reference voltage is generated by an on-chip voltage reference and the gain is adjusted using the gain select pins.

The digital output can be routed to the serial interface port, which enables the user to connect the AD7492BRUZ-5 to a microcontroller. The serial interface port can be configured to either SPI or I2C protocol depending on the user’s preference. As the AD7492BRUZ-5 is an 8-channel ADC, it allows for simultaneous sampling of the eight analog signals. This can be done by writing a 0x1 to the start bit of the AD7492BRUZ-5 and then enabling the multiplexer select pins to route the signal from different channels to the SAR block.

The AD7492BRUZ-5 provides an excellent performance in terms of noise, linearity, and speed. The low power consumption makes it suitable for use with battery operated systems. Additionally, the serial interface enables the user to configure the device and retrieve the data without any extra wiring, thereby reducing the cost and complexity of the system.
