This document introduces the features of ADuC836 MicroConverter ® Dual 16-Bit μ-p ADCs with Embedded 62 kB Flash MCU.
The ADuC836 is a MicroConverter® dual 16‑bit ADC with an integrated 8051‑based MCU, 62 KB of on‑chip flash program memory, 4 KB of data memory, and 2304 bytes of RAM. It provides two independent high‑resolution ADCs, a 12‑bit DAC, temperature sensor, dual current sources, and a range of digital peripherals such as UART, SPI, and multiple timers, making it suitable for intelligent sensors, weigh scales, portable instrumentation, and data‑logging applications.
Key specifications include 16‑bit resolution with no missing codes, a conversion rate of 5.4 Hz on both channels, selectable operating voltages (AVpp 2.7‑3.6 V or 4.75‑5.25 V), low power consumption (≈19 mA normal mode at 5 V), and availability in 52‑lead MQFP and 56‑lead LFCSP packages covering temperature ranges from –40 °C to +125 °C.
