ADuC832 is a microcontroller from Analog Devices that includes 12-bit ADCs and DACs, as well as an embedded 62 kB Flash MCU.
The ADuC832 is a 12‑bit MicroConverter integrating an 8‑channel ADC, dual 12‑bit DACs, on‑chip 62 kB flash program memory, 4 kB data memory and an 8051‑compatible MCU core. It operates from 3 V or 5 V supplies and includes peripherals such as UART, SPI, PWM, watchdog timer, and power‑supply monitor.
The datasheet provides full electrical specifications, absolute maximum ratings, pin configurations for the 52‑lead QFP and 56‑lead CSP packages, and ordering information. Power consumption is detailed for normal, idle and power‑down modes, and the device’s temperature range is specified from –40 °C to +125 °C for industrial use.
