Overview
The AD7995YRJZ-0RL is a 10-bit, low-power successive approximation analog-to-digital converter (ADC) featuring an I2C-compatible serial interface. It integrates four single-ended analog input channels and operates from a single 2.7 V to 5.5 V supply. The device supports standard, fast, and high-speed I2C modes 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 Y-version component is qualified for automotive applications and functions within a temperature range of −40°C to +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 Analog Devices documentation to confirm package type and temperature grade. Ensure compatibility with existing I2C bus addresses, as the AD7995 offers two distinct versions for address selection. Confirm that the required voltage levels align with the specified 2.7 V to 5.5 V operating range before integration.
Selection Notes
Select this component when a compact 8-lead SOT-23 package is required for multi-channel signal digitization. The AD7995 provides a balance of resolution and speed suitable for battery-operated devices. Consider the available I2C addresses if multiple units are placed on the same bus line. Verify thermal requirements against the specified industrial temperature range.
Part Context
The AD7995 belongs to the AD7991/AD7995/AD7999 family of ADCs, differentiated primarily by resolution. While the AD7991 offers 12-bit resolution and the AD7999 provides 8-bit resolution, the AD7995 delivers 10-bit performance. All variants share the same physical footprint and I2C interface architecture.
Replacement Considerations
The AD7991 and AD7999 are functionally similar but offer different resolutions. Direct substitution requires verifying that the resolution difference meets system accuracy requirements. Other parts in the series may require software adjustments due to register structure variations.
