AD7995YRJZ-0500RL7

Overview

The AD7995YRJZ-0500RL7 is a 10-bit successive approximation analog-to-digital converter (ADC) from Analog Devices, packaged in an 8-lead SOT-23. It features four single-ended analog input channels and supports I2C-compatible serial interfaces including standard, fast, and high-speed modes. The device operates on a single power supply ranging from 2.7 V to 5.5 V with a typical conversion time of 1 µs. It includes a track-and-hold amplifier capable of handling input frequencies up to 14 MHz. The part is specified for industrial temperatures 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 shutdown mode for low power 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 documentation to confirm package type and temperature range. Confirm that the component matches the required I2C address variant for system integration. Ensure compatibility with the target voltage supply levels before procurement.

Selection Notes

Select this model when a 10-bit resolution ADC with an integrated multiplexer is required. It is suitable for applications needing multiple single-ended inputs within a compact footprint. Consider the I2C bus speed requirements and available address variants when designing the system architecture.

Part Context

This component belongs to the AD7991/AD7995/AD7999 family of low-power, 4-channel SAR ADCs. The AD7995 specifically provides 10-bit resolution, distinguishing it from the 12-bit AD7991 and 8-bit AD7999 models. All variants share the same pinout and functional block diagram while differing in resolution and accuracy specifications.

Replacement Considerations

The AD7995YRJZ-1RL7 is a verified substitute offering identical 10-bit resolution, 4-channel configuration, and SOT-23-8 packaging. Both parts support the same I2C interface and operating voltage ranges.
