TDA1013B/N2,112

Overview

The TDA1013B/N2,112 is a 4 W audio power amplifier with integrated DC volume control in a 9-lead SIL plastic package. It operates on a supply voltage range of 10 V to 40 V and delivers up to 4.2 W output power into an 8 Ω load at 10% THD. The device features a logarithmic gain control range exceeding 80 dB via a 2 V to 6.5 V control voltage. Key electrical parameters include a typical total harmonic distortion of 0.15% at 2.5 W output and a maximum repetitive peak output current of 1.5 A.

Feature Summary

• Integrated DC volume control stage providing a logarithmic characteristic with a wide control range.
• Fixed open-loop gain architecture requiring minimal external components for stability.
• Built-in thermal protection circuitry to safeguard the device during operation.
• Pin-compatible design allowing direct replacement for the TDA1013A variant.

Applications

• Television receivers
• Battery-fed apparatus
• Mains-powered record players

Procurement Notes

Verify that the specific N2,112 suffix matches the required packaging configuration, as ordering suffixes can dictate reel or tape specifications. Confirm the component date code aligns with project requirements due to the July 1994 publication date of the specification. Ensure the application environment does not exceed the absolute maximum ratings, particularly regarding junction temperature and supply voltage limits.

Selection Notes

Select this component when a single-supply audio solution with built-in volume adjustment is required. It is suitable for designs needing a wide supply voltage tolerance between 10 V and 40 V. Consider the 9-lead SIL package constraints for PCB layout. Verify that the 4 W output capability meets the speaker impedance and power requirements of the target system.

Part Context

Originally manufactured by Philips Semiconductors, now part of NXP USA Inc., the TDA1013B belongs to a family of audio power amplifiers designed for consumer electronics. It serves as a successor or alternative to the TDA1013A, maintaining pin compatibility while offering specific performance characteristics for audio signal processing in standard household appliances.

Replacement Considerations

The TDA1013A is officially documented as pin-compatible. Verify functional equivalence before substitution, as internal circuit variations may exist despite identical pinouts. No other substitute part numbers are confirmed in the provided documentation.

FAQ

How is the volume controlled in the TDA1013B?

Volume is controlled via a DC voltage applied to pin 7, ranging from 2 V to 6.5 V, which adjusts the gain logarithmically over a range of more than 80 dB.

What is the maximum supply voltage for the TDA1013B?

The maximum supply voltage (VP) rating is 40 V, although the typical operating range specified is 10 V to 18 V.
