AD7730BNZ Description

Short technical summary and product information.

The AD7730BNZ from Analog Devices is a complete analog front end designed for precision weigh-scale and pressure measurement systems. This 24-bit Sigma-Delta Analog-to-Digital Converter (ADC) accepts low-level signals directly from transducers and outputs a serial digital word.

 

Key features include 24-bit resolution, a sampling rate of 1.2 kS/s, and a signal-to-noise ratio of 123dB. It offers a programmable gain front end, buffered differential inputs, and operates with a 5V supply. The device supports SPI and 3-wire serial communication interfaces.

 

With an offset drift of 5 nV/°C and a gain drift of 2 ppm/°C, the AD7730BNZ ensures high accuracy over temperature variations. It is suitable for applications requiring high resolution and low drift, such as industrial weighing systems and pressure sensors.

 

The component is supplied in a 24-pin PDIP package suitable for through-hole mounting. It operates within a temperature range of -40°C to 85°C.
