This document describes the features and characteristics of the Integrated Precision Battery Sensor ADuC7034 Rev. B, including high precision ADCs, dual channel simultaneous sampling, programmable ADC throughput, current channel, voltage channel, temperature channel, and microcontroller ARM7TDMI core.
The document describes the ADuC7034, an integrated precision battery sensor designed specifically for automotive systems. It combines high-precision analog-to-digital converters (ADCs) with a microcontroller to manage battery sensing tasks.
Key features include dual-channel simultaneous sampling 16-bit Z-A ADCs for current and voltage/temperature channels, programmable gain from 1 to 512, and digital comparators. The device operates directly from a 12 V battery supply and includes an ARM7TDMI core with 32 kB of Flash memory.
