Overview
The ACPL-785E-300 is a hermetic optically isolated amplifier manufactured by Broadcom Limited. It features a single-channel architecture with an 8 V/V gain and a 100 kHz bandwidth. The device operates within a supply voltage range of 4.5 V to 5.5 V, consuming 10.7 mA of quiescent current. Key electrical specifications include a common-mode rejection ratio (CMRR) of 69 dB and an input offset voltage (Vos) of 600 uV. The input bias current is specified at -570 nA. It is housed in a DIP-8 Gull Wing package suitable for surface mount installation and supports an operating temperature range from -55 C to +125 C.
Feature Summary
- Hermetic optical isolation for high-reliability environments
- Single-channel precision amplification with fixed gain
- Wide industrial operating temperature range
Applications
- High-voltage measurement systems
- Industrial process control instrumentation
- Power monitoring equipment
Procurement Notes
Verify the specific suffix '300' against official Broadcom documentation to confirm packaging configuration and tape-and-reel specifications. Ensure compatibility with existing board layouts requiring DIP-8 gull-wing packages. Confirm that the hermetic seal requirement aligns with the application's environmental protection standards before finalizing procurement orders.
Selection Notes
Select this component when high isolation reliability and wide temperature tolerance are required. The fixed 8 V/V gain suits applications needing precise signal scaling without external feedback networks. Consider the 100 kHz bandwidth limit for dynamic signal requirements. Verify that the 600 uV input offset voltage meets the system's accuracy constraints for low-level signal processing tasks.
Part Context
This part belongs to the ACPL-5 series of optically isolated amplifiers. It represents a specialized category of linear optocouplers designed for precision analog signal transmission across isolation barriers. Unlike digital optocouplers, it maintains signal linearity and amplitude fidelity while providing galvanic separation between input and output circuits.
Replacement Considerations
Consult official Broadcom substitution guides for verified alternatives. Generic optocoupler replacements may not match the hermetic sealing or precision amplifier characteristics.
