NJM2521M-TE1

Audio Special Purpose Overview

The NJM2521M-TE1 is a 3-input, 1-output audio switch manufactured by Nisshinbo Micro Devices Inc. (formerly New Japan Radio). It utilizes bipolar technology and features two bias-type inputs alongside one buffer-type output. The device operates within a supply voltage range of +4.75V to +13V. Key electrical characteristics include a typical input impedance of 58kΩ and crosstalk of -70dB. The component is housed in an 8-DMP surface-mount package.

Audio Special Purpose Feature Summary

• 3-Input, 1-Output Configuration: Supports selection among three audio channels.
• Bipolar Technology Design: Provides a typical input impedance of 58kΩ.
• High Isolation: Offers typical crosstalk of -70dB.
• Wide Operating Voltage Range: Functions reliably with supply voltages from +4.75V to +13V.

Audio Special Purpose Procurement Notes

Verify the specific ordering suffix 'TE1' against the manufacturer's documentation to confirm tape and reel packaging details. Confirm that the 8-DMP package variant matches the required footprint for the target design. Check for any product discontinuation notices or lifecycle status updates directly from Nisshinbo Micro Devices before finalizing procurement plans.

Audio Special Purpose Selection Notes

Select this component when a single-channel audio path requires switching between three independent sources. Ensure the application voltage stays within the +4.75V to +13V range. Consider the 8-DMP surface-mount package constraints and verify that the 58kΩ input impedance aligns with the source signal requirements. Compare performance metrics like crosstalk against alternative switches if strict audio fidelity is critical.

Audio Special Purpose Part Context

The NJM2521 belongs to the family of audio switch ICs designed for consumer and industrial audio equipment. It serves as a functional alternative to mechanical relays or other solid-state switches in multi-source audio setups. The M-variant specifically denotes the DMP8 surface-mount package option, distinguishing it from DIP or SSOP versions within the same functional series.
