AD7788ARMZ-REEL

Analog To Digital Converters (ADC) Overview

The AD7788ARMZ-REEL is a low-power, 16-bit Sigma-Delta analog-to-digital converter (ADC) from Analog Devices. It operates on a single supply voltage ranging from 2.5 V to 5.25 V and features an internal clock oscillator that eliminates the need for external timing components. The device provides a fixed output data rate of 16.6 Hz, which enables simultaneous rejection of both 50 Hz and 60 Hz power line interference. It incorporates a fully differential analog input, an external reference input, and a VDD monitor channel. The component utilizes a 3-wire serial interface compatible with SPI, QSPI, MICROWIRE, and DSP systems.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific grade (A or B) required for your application temperature range before ordering. Confirm that the REEL suffix matches your automated assembly equipment requirements. Ensure the external reference voltage falls within the specified operational limits relative to the supply voltage.

Analog To Digital Converters (ADC) Selection Notes

Select this component for applications requiring high resolution at low sampling rates. The AD7788 offers 16-bit resolution, whereas the AD7789 provides 24-bit resolution. Consider the A grade for industrial temperatures up to 105°C or the standard grade for commercial ranges. Verify compatibility with the system's serial interface logic levels.

Analog To Digital Converters (ADC) Part Context

This part belongs to the AD7788/AD7789 family of low-power, low-noise analog front ends designed for precision measurement. The AD7788 serves as the 16-bit variant within this series, sharing the same pinout and functional architecture as the 24-bit AD7789. Both devices target similar low-frequency sensing applications requiring minimal power consumption.

Analog To Digital Converters (ADC) Replacement Considerations

The AD7788BRMZ is a parameter-equivalent alternative within the same package type. The AD7790BRMZ is listed as a similar replacement option by distributors.
