The AD7703CR is a 20-bit sigma-delta analog-to-digital converter (ADC) from Analog Devices. It uses a charge-balance conversion technique with an on-chip digital filter providing a six-pole Gaussian response. The device offers a typical linearity error of 0.0015% and features on-chip self-calibration circuitry to null system offset and gain errors.
Key electrical specifications include a 4kSPS output data rate, single-ended analog input with a range of 0 V to +2.5 V (unipolar) or ±2.5 V (bipolar), and an external voltage reference. The digital interface is SPI-compatible, and the device operates from a single 5 V supply with typical power dissipation of 37 mW. A programmable low-pass filter allows corner frequency selection from 0.1 Hz to 10 Hz.
The ADC is housed in a 20-pin SOIC wide-body surface-mount package (20-SOIC, 0.295" width). It is specified for the industrial temperature range of -40°C to +85°C. Typical applications include industrial process control, weigh scales, portable instrumentation, and remote data acquisition systems.
The supply voltage is 5 V.
It comes in a 20-SOIC (0.295", 7.50mm Width) surface-mount package.
The operating temperature range is -40°C to +85°C.
According to the manufacturer page, the AD7703CR is not RoHS compliant.
The sampling rate is 4 kSPS.
It uses a SPI data interface.
It uses a Sigma-Delta architecture.
