Rochester Electronics Data Acquisition - Analog to Digital Converters (ADC) AD7710AR

The AD7710AR is a 24-bit sigma-delta analog-to-digital converter (ADC) designed for low-frequency measurement applications. It features a charge balancing architecture with no missing codes, ensuring high accuracy with a maximum nonlinearity of ±0.0015%. The device includes a 2-channel programmable gain front end, allowing gains from 1 to 128, and supports differential inputs. It is equipped with a low-pass filter that has programmable cutoff frequencies, enhancing its versatility in various applications. The AD7710AR can operate on single or dual supplies and has a low power consumption of 25 mW in normal operation, which can be reduced to 7 mW in power-down mode. It supports a bidirectional microcontroller serial interface for easy integration into smart systems, enabling software control over gain settings, channel selection, and calibration. The ADC is suitable for applications such as weigh scales, thermocouples, process control, and smart transmitters, making it a robust choice for engineers looking for reliable data acquisition solutions.
