AD7703ARZ Description

Short technical summary and product information.

The AD7703ARZ is a 20-bit sigma-delta analog-to-digital converter (ADC) manufactured by Analog Devices. It utilizes a sigma-delta architecture with a sample-and-hold (S/H) front end and provides a resolution of 20 bits. The device operates with a single 5 V supply and features an external voltage reference. The analog input range is 0 V to +2.5 V, and the converter achieves a maximum linearity error of 0.0015%.

 

The ADC offers a sampling rate of 4 kSPS and communicates via a serial peripheral interface (SPI). It includes on-chip self-calibration circuitry and a programmable low-pass filter. The operating temperature range is -40°C to +85°C, making it suitable for industrial environments.

 

The AD7703ARZ is housed in a 20-pin SOIC package with a width of 7.50 mm (0.295 inches) and is designed for surface mount mounting. This package is suitable for automated assembly and space-constrained applications.

 

Typical applications include industrial process control, weigh scales, portable instrumentation, and remote data acquisition. The device's low power consumption and flexible serial interface make it a good fit for battery-powered and distributed measurement systems.
