- Part Number:
- AD7710SQ
- Manufacturer:
- Analog Devices Inc.
- Ventron No:
- 3008336-AD7710SQ
- Description:
- IC ADC 24BIT DIFF INP 24-CDIP
- Datasheet:
- AD7710SQ
Description
The AD7710 is a complete analog front end for low-frequency measurement applications. It accepts low-level signals directly from a strain gage or transducer and outputs a serial digital word. It employs a sigma-delta conversion technique to realize up to 24 bits 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 settling time.
The part features two differential analog inputs and a differential reference input. Typically, one of the channels will be used as the main channel with the second channel used as an auxiliary input to measure a second voltage periodically. It can be operated from a single supply (by tying the Vss pin to AGND), provided that the input signals on the analog inputs are more positive than -30 mV. By taking the Vss pin negative, the part can convert signals down to -Vap on its inputs. The AD7710 thus performs all signal conditioning and conversion for a single- or dual-channel system.
The AD7710 is ideal for use in smart, microcontroller-based systems. Input channel selection, gain settings, and signal polarity can be configured in software using the bidirectional serial port. The AD7710 contains self-calibration, system calibration, and background calibration options, and also allows the user to read and write the on-chip calibration registers.
