ADN8810ACPZ

Overview

The ADN8810ACPZ is a high-precision laser driver IC manufactured by Analog Devices Inc., designed for tunable laser applications. It features a 12-bit current source capable of delivering output currents from 0 mA to 300 mA with low noise and long-term stability. The device operates on a single 5 V supply, drawing only 3 mA of quiescent current. It utilizes a 24-lead LFCSP package measuring 4 mm × 4 mm × 0.83 mm. The component supports data rates up to 125 Gb/s and functions within an operating temperature range of -40 °C to +85 °C.

Feature Summary

• High precision 12-bit current source architecture
• Low noise operation with long-term stability
• Integrated output fault indication logic
• Programmable maximum current limit

Applications

• Tunable laser current source
• Programmable high output current source
• Automatic test equipment

Procurement Notes

Verify the specific suffix (PZ) confirms the lead-free tray packaging variant when sourcing. Confirm RoHS compliance status as some variants may contain lead. Check moisture sensitivity level requirements for storage and handling. Ensure the 24-lead LFCSP footprint matches the target PCB design. Validate that the 5V single-supply requirement aligns with system power constraints.

Selection Notes

Select this component for applications requiring precise analog current control in optical systems. The 12-bit resolution offers sufficient granularity for most laser diode modulation needs. Consider the low 3 mA supply current for battery-operated or power-sensitive designs. The integrated fault indication simplifies system monitoring without external components. Evaluate the thermal performance within the specified -40 °C to +85 °C range.
