Описание AD7715ARZ-5
The AD7715ARZ-5 is a complete analog front end sigma-delta Analog-to-digital Converter (ADC) for low frequency measurement applications. The part can accept low level input signals directly from a transducer and outputs a serial digital word. It employs a sigma-delta conversion technique to realize up to 16-bit of no missing codes performance. The input signal is applied to a proprietary programmable gain front end based around an analog modulator. The modulator output is processed by an on-chip digital filter. The first notch of this digital filter can be programmed via the on-chip control register allowing adjustment of the filter cutoff and output update rate. It features a differential analog input as well as a differential reference input. It is ideal for use in smart, microcontroller or DSP-based systems. It features a serial interface that can be configured for 3-wire operation.
• Operates from a single supply
• Programmable gain front end gains of 1, 2, 32 and 128
• Differential input capability
• 3-wire serial interface SPI/QSPI™/MICROWIRE™/DSP compatible
• Ability to buffer the analog input
