Rochester Electronics Data Acquisition - Analog to Digital Converters (ADC) AD7715ARU-5

The AD7715ARU-5 is a 16-bit sigma-delta analog-to-digital converter (ADC) designed for low-frequency measurement applications. It features a charge-balancing architecture that ensures no missing codes and offers a nonlinearity of 0.0015%. The device supports a programmable gain front end with gains of 1, 2, 32, and 128, allowing it to handle a variety of input signal ranges, including both unipolar and bipolar configurations. This ADC operates on a single supply voltage of either 3 V or 5 V, with a maximum supply current of 450 µA, making it suitable for low-power applications. It includes a three-wire serial interface compatible with SPI, QSPI, MICROWIRE, and DSP systems, facilitating easy integration into microcontroller or DSP-based designs. The AD7715ARU-5 also incorporates on-chip calibration options to minimize gain and offset errors, enhancing overall accuracy. The device is available in a 16-lead TSSOP package, making it compact for space-constrained applications. Its low noise performance and programmable digital filtering capabilities further contribute to its suitability for precision measurement tasks.
