ADM1293-2AACPZ-RL

Overview

The ADM1293-2AACPZ-RL is a high-accuracy integrated digital power monitor manufactured by Analog Devices. It utilizes an on-chip 12-bit analog-to-digital converter (ADC) to provide precise digital monitoring of current, voltage, and power. The device communicates via a PMBus-compatible I2C interface. Key electrical specifications include input offset voltages of ±80 mV, ±40 mV, and ±160 mV depending on the configuration. Voltage ranges supported are 10 V to 20 V with VRANGE = 21 V, 3.6 V to 7.4 V with VRANGE = 7.4 V, and 0.6 V to 1.2 V with VRANGE = 1.2 V. The operating temperature range is specified from −40°C to +85°C.

Feature Summary

• Integrates a 12-bit ADC for direct digital measurement of electrical parameters
• Supports PMBus-compatible I2C communication protocol
• Provides simultaneous monitoring of current, voltage, and calculated power

Applications

• Digital power supply monitoring in server infrastructure
• Battery management systems requiring precise state-of-charge data
• Industrial equipment power rail supervision

Procurement Notes

Verify the specific suffix 'RL' indicates reel packaging when sourcing. Confirm the '-2AA' variant matches the required voltage range and accuracy specifications for the target application. Ensure compatibility with the host controller's I2C address and PMBus command set before integration. Check for any recent lifecycle notices regarding availability or obsolescence.

Selection Notes

Select this component when high precision is required for power monitoring without external sensing amplifiers. The integrated 12-bit ADC reduces bill of materials complexity. Consider the operating temperature range of −40°C to +85°C for environmental suitability. Verify that the PMBus interface aligns with the system's communication architecture.
