The AD7730BRZ is a complete analog front end Bridge Transducer Analog-to-digital Converter (ADC) for weigh-scale and pressure measurement applications. The device accepts low-level signals directly from a transducer and outputs a serial digital word. The input signal is applied to a proprietary programmable gain front end based around an analog modulator. The modulator output is processed by a low pass programmable digital filter, allowing adjustment of filter cut-OFF, output rate and settling time. The part features two buffered differential programmable gain analog inputs as well as a differential reference input. The serial interface on the part can be configured for three-wire operation and is compatible with microcontrollers and digital signal processors. It contains self-calibration and system calibration options and features an offset drift of less than 5nV/°C and a gain drift of less than 2ppm/°C.

• Buffered differential inputs
• Programmable filter cutoffs
• Specified for drift over time
• 2-channel programmable gain front end
• On-chip DAC for offset/TARE removal
• FASTStep™ Mode
• AC or DC excitation
• Single supply operation
