Overview
The SPA2629LR5H-B is a miniature, high-performance, low-power bottom port silicon microphone manufactured by Syntiant. It features an omnidirectional directional property and operates within a frequency range of 100 Hz to 10 kHz. The device requires an operating supply voltage of 3.6 V and draws an operating supply current of 120 uA. Designed for surface mount technology (SMD/SMT), its physical dimensions are 3.35 mm x 2.5 mm x 0.98 mm. The component supports a minimum operating temperature of -40 C.
Feature Summary
- Miniature bottom port silicon construction
- Low power consumption design
- Omnidirectional acoustic response
Applications
- Surface mount electronic assemblies
- Temperature-sensitive environments requiring -40 C operation
Procurement Notes
Verify availability status as the product may be discontinued or no longer available through standard distributors like DigiKey. Confirm the manufacturer designation, noting that Knowles Electronics is associated with this part number in some listings. Ensure the specific suffix LR5H-B matches the required package and performance specifications before ordering.
Selection Notes
Select this component when a low-profile, low-power MEMS microphone is required for SMD applications. Consider the 3.6 V supply requirement and 120 uA current draw against system power budgets. Verify compatibility with the 100 Hz to 10 kHz frequency range and -40 C minimum operating temperature for the intended environment.
Part Context
This part belongs to the Syntiant SPA2629 series of silicon microphones. It is distinct from other Syntiant products like the SPH21C3LR5H-1 or vibration sensors such as the V2S200DZA. The component represents a specialized audio input solution designed for compact electronic devices requiring efficient power usage.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided documentation. Consult official Syntiant or Knowles channels for direct replacements or updated product line information.
