Procurement Notes

Verify the specific suffix designation against official documentation to confirm packaging type and handling requirements. Confirm that the procurement channel provides appropriate ESD protection for bare die components. Ensure compatibility with the required assembly substrate and bonding techniques specified in the datasheet before finalizing orders.

Selection Notes

Select this component for designs requiring high-speed signal conversion with adjustable DC offset and overload compensation. Evaluate the need for separate versus integrated photodiode supply configurations based on system noise and layout constraints. Consider the bare die format when designing custom substrates and bond wire lengths to minimize parasitic effects.
