AD7999YRJZ-1500RL7

Overview

The AD7999YRJZ-1500RL7 is an 8-bit, low-power successive approximation analog-to-digital converter (ADC) featuring four single-ended analog input channels and an I2C-compatible serial interface. It operates from a single 2.7 V to 5.5 V supply with a typical conversion time of 1 µs. The device supports standard, fast, and high-speed I2C modes and includes automatic shutdown functionality. It is housed in an 8-lead SOT-23 package and rated for operation between -40°C and +125°C.

Feature Summary

Four single-ended analog input channels or three inputs with one reference input channel
I2C-compatible serial interface supporting standard, fast, and high-speed modes
Automatic power-down mode for low energy consumption
Reference derived from the power supply or external reference

Applications

System monitoring
Battery-powered systems
Data acquisition
Medical instruments

Procurement Notes

Verify the specific ordering suffix against official Analog Devices documentation to confirm package type and temperature range. Confirm that the component matches the required I2C address configuration, as the AD7999 has a fixed address compared to other variants in the series. Ensure compatibility with system voltage levels before integration.

Selection Notes

Select this part when eight-bit resolution is sufficient for the application's accuracy requirements. Consider the 14 MHz full-power bandwidth if higher frequency signal processing is needed. Verify that the I2C bus speed requirements align with the supported standard, fast, and high-speed modes. Check power constraints against the specified operating current values.

Part Context

This component belongs to the AD7991/AD7995/AD7999 family of low-power ADCs. While sharing the same package and interface, it differs from the AD7991 (12-bit) and AD7995 (10-bit) primarily in resolution. All variants utilize the same 8-lead SOT-23 footprint and support similar operational characteristics.
