NJM2520M

Audio Special Purpose Overview

The NJM2520M is a 2-input, 1-output audio switch IC manufactured by Nisshinbo Micro Devices Inc. It features two bias-type inputs and one buffer-type output, configured as a single-pole double-throw (SPDT) switch. The device operates within a supply voltage range of +4.75V to +13V and utilizes bipolar technology. Key electrical characteristics include a typical input impedance of 58 kΩ and a typical crosstalk of -70 dB.

Audio Special Purpose Feature Summary

• 2-input, 1-output configuration with bias-type inputs and buffer-type output
• Low crosstalk performance (-70 dB typ.)
• High input impedance (58 kΩ typ.)
• Operates on bipolar technology with supply voltage from +4.75V to +13V
• Housed in an 8-DMP (8-SOIC) surface-mount package

Audio Special Purpose Procurement Notes

The NJM2520M is listed as an obsolete or end-of-life product by the manufacturer. Verification of availability requires checking distributor inventories for remaining stock or alternative sourcing channels. Designers should consider component lifecycle status when planning production runs.

Audio Special Purpose Selection Notes

Select the NJM2520M for applications requiring a simple analog audio switch with low distortion and high input impedance. Ensure the supply voltage stays within the +4.75V to +13V range. Verify that the 8-DMP package footprint matches the PCB layout requirements.

Audio Special Purpose Part Context

The NJM2520M belongs to the NJM2520 series of audio switches. Other variants in this series include the NJM2520D (DIP8 package) and NJM2520V (SSOP8 package), offering different physical form factors while maintaining identical electrical specifications.
