ADM1293-1BACPZ

Overview

The ADM1293-1BACPZ is a digital power monitor featuring an integrated 12-bit analog-to-digital converter for precise measurement of current, voltage, and power. It supports input supply voltages ranging from 2.95 V to 20 V and operates within a temperature range of -40°C to +105°C. The device utilizes a PMBus-compatible I2C interface for communication and is housed in a 16-LFCSP (4x4) package.

Feature Summary

• Integrates a 12-bit ADC for high-precision digital monitoring of electrical parameters
• Supports PMBus-compatible I2C interface for system communication
• Designed for single-phase energy metering applications

Applications

• Single-phase energy metering systems
• Digital power monitoring in industrial equipment
• Battery management systems requiring precise voltage and current tracking

Procurement Notes

Verify the exact suffix and package type during procurement, as Analog Devices often uses specific endings to denote tape-and-reel quantities or variant specifications. Confirm availability through authorized distributors, as stock levels fluctuate. Ensure the ordering part number matches the required 16-LFCSP package and operating temperature range specified in the official datasheet to avoid integration errors.

Selection Notes

Select this component when high accuracy is required for single-phase monitoring via a digital interface. The 12-bit resolution provides sufficient detail for most metering tasks. Consider the 2.95 V to 20 V input range to ensure compatibility with the target power rail. The PMBus interface simplifies integration into existing I2C-based control architectures without additional protocol converters.

Part Context

This device belongs to the ADM1293 family of digital power monitors from Analog Devices. These components are designed to replace traditional analog sensing circuits by providing direct digital output. The family typically includes variants with different pin counts or interfaces, but the ADM1293-1BACPZ specifically targets compact single-phase applications using the 16-pin LFCSP form factor.

Replacement Considerations

Direct substitutes may include other ADM1293 variants with compatible pinouts, such as those in TSSOP packages if board space allows. Verify that any replacement maintains the 12-bit ADC resolution and PMBus compatibility. Cross-reference with ADM1294 series only if quad-channel monitoring is not required and single-channel functionality suffices.
