Overview
The NJM2174V-TE2 is a low voltage audio line amplifier with a mute function, designed for digital audio items. It operates within a supply voltage range of 4.5 to 5.5 V and draws a typical operating current of 2.5 mA at 5 V. The device features a closed loop voltage gain of 3.5 dB typ. at 1 kHz and provides a maximum output voltage of 4 dBV typ. at THD=0.1%. Key electrical characteristics include a total harmonic distortion of 0.005% typ., an output noise voltage of -95 dBV (A-weighted), and a channel separation of 90 dB typ. The integrated mute function achieves a mute level of -85 dB typ.
Feature Summary
- Integrated mute circuit that realizes very low turn-noise at power on/off
- Internal closed loop voltage gain suitable for amplifying small line signals in digital audio items
- Bipolar technology construction for reliable performance
Applications
- Digital audio items with line out
- Audio line amplification
- Small line signal amplification in consumer electronics
Procurement Notes
Verify the specific ordering suffix TE2 against the manufacturer's official documentation to ensure correct packaging and reel specifications. Confirm RoHS compliance status directly from the datasheet or component certification documents before procurement. Ensure the SSOP-14 package dimensions match your PCB footprint requirements precisely.
Selection Notes
Select this component when a low-voltage audio line amplifier with integrated mute functionality is required for digital audio applications. Consider the 4.5 to 5.5 V operating range and bipolar technology constraints. Evaluate the 3.5 dB internal gain against external resistor requirements if higher gain is needed. Verify thermal dissipation limits within the specified operating temperature range.
Part Context
The NJM2174 belongs to Nisshinbo Micro Devices' lineup of audio ICs designed for consumer electronics. It is part of a series focusing on low voltage operation and integrated signal processing features like muting. This component serves as a specialized solution for line-level signal handling in portable and desktop digital audio equipment.
Replacement Considerations
Consult official cross-reference lists for verified substitutes. Ensure any replacement matches the SSOP-14 package, 4.5-5.5 V supply range, and mute control logic compatibility.
