Overview
The AD7995YRJZ-1RL 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 power supply. The device supports standard, fast, and high-speed I2C modes with a typical conversion time of 1 µs. It utilizes an external reference voltage applied via the VIN3/VREF pin or derives the reference from the VDD supply. The 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 with integrated multiplexer
- I2C-compatible serial interface supporting standard, fast, and high-speed modes
- Automatic shutdown mode for minimal power consumption
- External or internal reference voltage selection
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 address versions. Confirm that the external reference voltage requirements align with the system design specifications before procurement.
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 general-purpose data acquisition. Consider the available I2C addresses if multiple devices are used on the same bus line. Verify that the input voltage range matches the sensor output levels.
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, pinout, and I2C interface architecture, facilitating design flexibility across different precision requirements.
Replacement Considerations
The AD7991YRJZ-1RL and AD7999WYRJZ-1RL are direct pin-compatible alternatives within the same datasheet. Substitution requires verification of resolution requirements and I2C address availability, as the AD7995 shares addresses with the AD7991.
