Overview
The AD7788BRMZ-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 provides a fixed output update rate of 16.6 Hz, ensuring simultaneous rejection of 50 Hz and 60 Hz interference. The device incorporates one differential analog input channel and utilizes an external reference voltage. It communicates via a 3-wire serial interface compatible with SPI, QSPI, MICROWIRE, and DSP standards. The component is housed in a compact 10-lead MSOP package.
Feature Summary
- Integrated Sigma-Delta architecture with internal clocking for simplified system design
- Low power consumption suitable for battery-operated applications
- Differential analog input configuration optimized for noise rejection
- Versatile serial interface supporting multiple communication protocols
Applications
- Smart transmitters
- Battery-powered instrumentation
- Portable measurement devices
- Sensor measurement systems
- Weigh scales
Procurement Notes
Verify the specific B-grade temperature range (-40°C to +105°C) against application requirements. Confirm the presence of the REEL suffix indicates tape-and-reel packaging rather than tube or cut tape formats. Ensure the ordering part number matches the exact 16-bit resolution variant required for the design.
Selection Notes
Select this component when a 16-bit resolution is sufficient for the target application's dynamic range requirements. Consider the AD7789 if higher 24-bit resolution is necessary. Evaluate the fixed 16.6 Hz data rate to ensure it meets the system's bandwidth constraints. Verify compatibility with the available external reference voltage range.
Part Context
This component belongs to the AD7788/AD7789 family of low-power, low-noise analog front ends designed for precision measurement applications. The AD7788 serves as the 16-bit resolution counterpart to the 24-bit AD7789 within the same series. Both variants share identical pinouts, interfaces, and core architectural features while differing primarily in resolution and noise performance specifications.
Replacement Considerations
The AD7788ARMZ is a parameter-equivalent alternative within the same product family. The AD7790BRMZ is listed as a similar replacement option by distributors.
