Analog Devices Inc. ADUC824BSZ MicroConverter®

The ADUC824BSZ is a highly integrated MicroConverter® from Analog Devices Inc., which combines a high-performance multichannel analog-to-digital converter (ADC) with a low-power, fully programmable 8-bit MCU. This device is well-suited for a variety of applications, including industrial control systems, smart sensors, instrumentation, and automated test equipment, thanks to its precision measurement capabilities and flexible interfacing options.

At the heart of the ADUC824BSZ is a 12-bit ADC with eight single-ended channels or four differential channels, which provides excellent accuracy for demanding measurements. The ADC features a track-and-hold amplifier, a temperature sensor, and a 4.096 V precision bandgap reference, ensuring reliable performance across a wide range of environmental conditions.

The integrated MCU is based on the 8052 microcontroller architecture, offering 62 KB of nonvolatile Flash/EE memory, which is partitioned into 60 KB of user Flash/EE and 2 KB of user EEPROM. This generous memory allocation allows for complex program code and data storage without the need for external memory components, simplifying design and reducing system costs.

Additional features of the ADUC824BSZ include two 12-bit digital-to-analog converters (DACs), a programmable watchdog timer, two 16-bit timer/counters, and a versatile serial I/O controller that supports UART, SPI, and I²C communication protocols. These built-in peripherals enable the MicroConverter® to handle a wide array of tasks, from simple data logging to advanced closed-loop process control.

The device operates from a 2.7 V to 5.25 V power supply, catering to both 3 V and 5 V systems, and it is available in a 52-lead MQFP (Metric Quad Flat Pack) package. The ADUC824BSZ also features a power-saving sleep mode, which significantly reduces power consumption when the device is not actively processing data.

For engineers and designers looking for a robust, single-chip solution that minimizes board space and maximizes functionality, the ADUC824BSZ MicroConverter® from Analog Devices Inc. offers a compelling option that balances performance, flexibility, and ease of use.
