ADuC831 is a single-chip microcontroller that integrates 8-channel, 247 kSPS 12-bit ADC, 2 12-bit (monotonic) voltage output DACs, dual output PWM/sine wave DACs, temperature sensor, voltage reference, etc.
The ADuC831 is a fully integrated 12‑bit ADC/DAC microconverter with an 8052‑compatible MCU core, 62 kB of flash program memory, and a range of on‑chip peripherals such as UART, SPI, PWM and a temperature sensor. It is designed for high‑speed data acquisition, precision instrumentation, and smart‑sensor applications.
The device operates from 3 V or 5 V, offers a power‑down current as low as 20 pA, and is available in a 52‑lead plastic quad flat‑pack and a 56‑lead chip‑scale package. Detailed specifications, pin assignments, absolute maximum ratings and ordering information are provided throughout the document.
