LED Indication - Discrete datasheet and documents for 4040
LED Indication - Discrete Overview
The Adafruit Industries LLC model 4040 is not a recognized standalone component identifier within the provided documentation. The source material references multiple distinct products with similar numeric suffixes, including the VCNL4040 optical sensor, LM4040 voltage reference, and TS4040 shunt reference. No specific datasheet or technical specification sheet is associated with the exact part number 'Adafruit 4040'. Consequently, no verified electrical parameters, package types, or functional metrics can be attributed to this specific designation.
LED Indication - Discrete Procurement Notes
Verify the complete manufacturer part number before procurement. The provided data contains entries for VCNL4040, LM4040, and TS4040, but lacks a specific entry for 'Adafruit 4040'. Confirm the intended function—optical sensing, voltage referencing, or hardware kit—to ensure the correct component is ordered. Cross-reference the full alphanumeric code with official distributor catalogs to avoid mismatched components.
LED Indication - Discrete Selection Notes
Selection requires clarification of the specific device family. If high-precision voltage referencing is needed, consider the LM4040 or TS4040 series. For proximity and ambient light sensing, the VCNL4040 is documented. Hardware expansion boards like the MatrixPortal M4 are also listed but do not match the '4040' model string directly. Ensure the application requirements align with the specific capabilities of the identified sub-family component.
LED Indication - Discrete Part Context
The identifier '4040' appears as a suffix in several unrelated product lines within the knowledge base. It denotes the VCNL4040 optical sensor by Vishay, the LM4040 precision shunt voltage reference, and the TS4040 micro-power shunt reference. Adafruit distributes these components or uses them in shields, but 'Adafruit 4040' itself is not a defined part number in the provided text. Contextual analysis suggests potential confusion between these distinct semiconductor devices.
LED Indication - Discrete FAQ
Is there an Adafruit-branded component specifically named '4040'?
No. The provided documentation does not list a standalone component with the exact part number 'Adafruit 4040'. The number appears as a suffix for third-party chips like the VCNL4040, LM4040, and TS4040.
What is the difference between LM4040 and VCNL4040?
The LM4040 is a precision shunt voltage reference providing stable output voltages. The VCNL4040 is a high-integration optical sensor combining an IR LED, ambient light sensor, and proximity sensor.
