Frequently Asked Questions

Q: What microcontroller is used on the ADS1256 ADC module and does it come pre-programmed?

A: The module features an STM32F030 microcontroller that comes pre-programmed with test DEMO software. The DEMO project source code is also provided, allowing you to modify or extend the firmware for your own data acquisition application.

Q: How many input channels does the ADS1256 module support, and what input modes are available?

A: The ADS1256 ADC module supports 8 channels via time-division multiplexed sampling. It can be configured for 8-channel single-ended inputs or any combination of differential inputs, giving you great flexibility for various measurement setups.

Q: What is the input voltage range for this 24-bit ADC conversion module?

A: The input voltage range depends on the buffer setting. With the input buffer disabled, the module accepts signals from 0–5V. With the input buffer enabled (which acts as a voltage follower to reduce leakage current errors from high-impedance sources), the range is 0–3V.

Q: What reference voltage accuracy does this ADC module offer?

A: The module uses a REF5025 precision reference chip providing a stable 2.5V reference voltage with a temperature drift of less than 3 PPM/°C. Each unit is calibrated using a 7.5-digit multimeter, and the reference voltage value is labeled on the rear of the module for your records.
