BA6566FP

Overview

The BA6566FP is a speech network integrated circuit manufactured by ROHM Semiconductor, designed for telephone applications. It operates within a supply voltage range of 2 V to 9.5 V and draws current between 5 mA and 90 mA depending on the configuration. The device supports operating temperatures from -35°C to +60°C and features a maximum power dissipation of 1.35 W. It is available in surface-mount packages including HSOP-24 and HTSSOP-24 variants, with suffixes such as DXE1, E1, and T1 denoting specific packaging or reel options.

Feature Summary

• Integrated speech network functionality for telephone circuits
• Supports standard telephone interface requirements
• Available in multiple surface-mount package configurations

Applications

• Telephone speech circuits
• Telecommunications equipment
• Voice processing systems

Procurement Notes

Verify the exact ordering suffix (e.g., DXE1, E1, T1) against the required package type and reel specification. Confirm availability status as some variants may be discontinued or end-of-life. Ensure the selected part matches the specific pinout and thermal requirements of the target design before procurement.

Selection Notes

Select the appropriate suffix based on the required package style (HSOP-24 vs HTSSOP-24) and tape/reel specifications. Check the operating temperature range suitability for the intended environment. Verify that the supply voltage and current consumption parameters align with the system power budget and interface constraints.

Part Context

The BA6566FP belongs to ROHM's family of telephone speech circuits. Variants like BA6566FP-E2 are explicitly marked as discontinued or end-of-life products. Other suffixes indicate different packaging or handling formats rather than functional changes. Designers should consult the specific datasheet for the chosen suffix to confirm mechanical and electrical details.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided source material. Engineers must evaluate alternative speech network ICs from other manufacturers based on pin compatibility and functional equivalence.
