AD7715ARU-5 - Brand New Analog Devices Analog To Digital Converters (ADCs)
-
Description
The AD7715ARU-5 is a complete analog front end for low frequency measurement applications. It is an analog-to-digital converter (ADC) that can accept low-level input signals directly from a transducer and outputs a serial digital word. The AD7715ARU-5 utilizes a Σ-Δ conversion technique to achieve up to 16 bits of no missing codes performance. It has a proprietary programmable gain front end based around an analog modulator and an on-chip digital filter. The digital filter allows for adjustment of the filter cutoff and output update rate via the on-chip control register.
