Analog Devices Inc. ADUC847BSZ32-5 MicroConverter®

The ADUC847BSZ32-5 is a highly integrated microconverter from Analog Devices Inc., combining a high-performance analog front-end with a multi-channel 24-bit sigma-delta (Σ-Δ) analog-to-digital converter (ADC) and an 8052 microcontroller core. This precision analog microcontroller is designed for direct interfacing to external precision sensors in both industrial and instrumentation applications.

At the heart of this device is a 24-bit Σ-Δ ADC with a programmable gain amplifier (PGA), which offers selectable gains from 1 to 128. This feature allows the ADUC847BSZ32-5 to interface directly with sensors that have a wide range of output voltages, providing flexibility in various application designs. The ADC also features a 21-bit effective resolution at 10Hz update rate, ensuring high precision in measurement tasks.

The integrated 8052 microcontroller core is clocked at 32.768 kHz, providing a low-power yet efficient processing capability for handling complex algorithms and control tasks. The ADUC847BSZ32-5 comes with 62KB of non-volatile Flash/EE memory, which is partitioned into two segments: 60KB of user Flash/EE and 2KB reserved for extended features. This memory space is ample for storing application code and data, thus reducing the need for additional external memory components.

Additional features of the ADUC847BSZ32-5 include eight single-ended or four differential analog input channels, two DACs (Digital-to-Analog Converters), a range of digital peripherals such as UART, SPI, I²C interfaces, and 32 general-purpose I/O pins. These features make the device highly adaptable to a variety of communication and control interfaces.

For power management, the ADUC847BSZ32-5 operates from a single 2.7V to 5.25V power supply, which is ideal for battery-powered or energy-efficient applications. The device also supports a wide operating temperature range of -40°C to +85°C, ensuring reliable performance in harsh environmental conditions.

In summary, the ADUC847BSZ32-5 from Analog Devices Inc. is a robust and versatile microconverter that offers high precision, ample memory, and a rich set of features, making it an excellent choice for advanced sensor interfacing and signal processing applications.
