TDA9830/V1,112

Video Processing Overview

The TDA9830 is a monolithic integrated circuit designed for TV sound AM-demodulation in L- and L'-standards. It integrates a wideband synchronous AM demodulator, an audio source selector, and a mute switch. The device operates with a primary supply voltage of 5 to 8 V or an alternative 12 V supply. Key electrical parameters include a typical supply current of 30 mA, an IF sensitivity of 60 μV RMS, and an AF output signal of 500 mV RMS at 54% modulation. The operating ambient temperature range extends from 0 °C to +70 °C.

Video Processing Feature Summary

• Adjustment-free wideband synchronous AM demodulator
• Integrated audio source selector and low-noise mute switch
• Dual power supply options: 5–8 V or 12 V
• Audio level compliance with EN50049 standard

Video Processing Applications

• TV sound AM-demodulation for L-standard receivers
• TV sound AM-demodulation for L'-standard receivers
• Audio source switching in television systems

Video Processing Procurement Notes

Verify the specific package variant required, as the TDA9830 family includes both DIP (SOT38) and SO (SOT109) packages. Confirm that the ordering suffix matches the desired physical form factor. Ensure the design supports the specified 5–8 V or 12 V supply rails. Check for RoHS compliance status if environmental regulations apply to the target market.

Video Processing Selection Notes

Select this component for applications requiring a single-chip solution for TV sound processing. It is suitable for designs utilizing L or L' sound standards. Consider the available supply voltage constraints when choosing between the 5–8 V and 12 V operational modes. Verify that the thermal resistance characteristics of the chosen package meet the system's heat dissipation requirements.

Video Processing Part Context

Manufactured by Philips Semiconductors, now NXP Semiconductors, the TDA9830 belongs to a series of integrated circuits for consumer electronics. It was published as a product specification in June 1994. The device represents a specialized solution for analog television audio processing, combining demodulation and switching functions into a single silicon die.
