AD7730LBRUZ 4.75V~5.25V Analog Front End (AFE) SMD IC TSSOP-24
The AD7730LBRUZ 4.75V~5.25V Analog Front End (AFE) SMD IC TSSOP-24 is a low-power, high-resolution analog front-end integrated circuit from Analog Devices, designed primarily for bridge transducer and precision measurement applications. It combines a programmable-gain analog front end, sigma-delta analog-to-digital conversion, programmable digital filtering, and a serial communication interface in a compact 24-lead TSSOP package. The device is particularly suitable for applications that require accurate measurement of low-level differential signals from sensors such as load cells and pressure transducers.
Features:
- Low-power analog front end for bridge transducer measurement applications.
- Integrated sigma-delta analog-to-digital converter.
- 24-bit conversion architecture with up to 110,000 peak-to-peak counts for the AD7730L.
- Two buffered differential programmable-gain analog input channels.
- Selectable unipolar and bipolar input ranges from 10mV to 80mV.
- Programmable digital filter with adjustable output rate and settling time.
