NJM2753V-TE1

Audio Special Purpose Overview

The NJM2753V-TE1 is a 3-input to 1-output stereo audio selector manufactured by Nisshinbo Micro Devices Inc. It integrates switches and buffer operational amplifiers using bipolar technology to achieve low output noise, low distortion, and high channel separation compared to general multiplexers or analog switches. The device operates within a supply voltage range of 4.7 V to 10 V and features a typical total harmonic distortion plus noise (THD+N) of 0.0009% at 1 kHz. It utilizes logic-level control inputs for channel selection and is housed in an SSOP-14 package.

• Low Output Noise: -114 dBV typ. (A-weighted)
• Low Distortion: 0.0009% typ. THD+N at 1 kHz
• High Channel Separation: 110 dB typ. at 1 kHz

Audio Special Purpose Applications

• Car Stereo audio routing
• General Audio Systems

Audio Special Purpose Procurement Notes

Verify the specific ordering suffix 'TE1' against the manufacturer's current documentation to confirm packaging details such as tape and reel specifications. Ensure that the SSOP-14 package dimensions align with the target PCB footprint requirements before finalizing procurement orders.

Audio Special Purpose Selection Notes

Select this component when a stereo audio switching solution with superior signal integrity is required over standard analog switches. The internal buffer amplifiers provide high input impedance and low output impedance, facilitating direct connection to subsequent audio stages without significant signal degradation or loading effects.

Audio Special Purpose Part Context

The NJM2753 belongs to the NJM2753 series of audio selectors. It offers pin compatibility with the NJM2752 (2-in-1-out) and NJM2755 (4-in-1-out) variants, allowing for design flexibility across different channel count requirements within the same product family while maintaining consistent control logic and interface characteristics.
