AD7995YRJZ-1500RL7

Overview

The AD7995YRJZ-1500RL7 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 accommodates input frequencies up to 14 MHz via its track-and-hold amplifier. The Y version is specified for an industrial temperature range of −40°C to +125°C and is housed in an 8-lead SOT-23 package.

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. Confirm that the component matches the required I2C address variant, as the AD7995 series offers two distinct versions with individual addresses. Ensure compatibility with the target system's voltage levels and bus speed requirements before finalizing procurement.

Selection Notes

Select this component when a compact 10-bit ADC with multiple channels is required in space-constrained designs. The choice between the A and Y versions depends on the operating temperature range needed for the application. Consider the available I2C addresses if multiple devices must share the same bus line within the system architecture.

Part Context

This part belongs to the AD7991/AD7995/AD7999 family of low-power, multi-channel ADCs. While sharing the same physical package and interface, the family differentiates by resolution: the AD7991 provides 12 bits, the AD7995 offers 10 bits, and the AD7999 delivers 8 bits. All variants utilize the same 8-lead SOT-23 footprint and I2C control logic.

Replacement Considerations

Direct substitutes within the same package include the AD7991YRJZ for higher resolution or the AD7999YRJZ for lower resolution. Verify pinout compatibility and software register mapping differences when migrating between these family members.
