Rochester Electronics Data Acquisition - Analog Front End (AFE) AD7730LBRU

The AD7730LBRU is a 24-bit analog front end (AFE) designed for weigh-scale and pressure measurement applications. It features a resolution of 230,000 counts and offers buffered differential inputs with programmable gain. The device operates with reference voltages ranging from 1V to 5V and includes an on-chip DAC for offset and TARE removal. The AD7730LBRU supports both AC and DC excitation and is capable of single supply operation. It provides a high level of performance with an offset drift of 5 nV/¬8C and a gain drift of 2 ppm/¬8C. The device also incorporates a programmable digital filter, allowing for adjustable filter cutoff, output rate, and settling time. The part is available in a 24-lead TSSOP package and is specified for operation over a temperature range of -40¬8C to +85¬8C. It is suitable for applications requiring high precision and stability in signal acquisition.
