Audio Processor 20-Pin SO T/R

The TDA7418 includes a high performance audio procesor with fully integrated 3-Band filters to process signals at audible frequencies. The digital control allows a full programming of the audioprocessor and filters characteristics.

Input Multiplexer PD/SE4: pseudo differential stereo input, programmable as single-ended input SE1: stereo single-end input SE2: stereo single-end input SE3: stereo single-end input input gain adjust from 0 to 15dB with 1dB steps internal offset-cancellation (AutoZero)

Loudness Second order frequency response programmable center frequency (400Hz/800Hz/2400Hz) 15dB with 1dB steps selectable low & high frequency boost selectable flat-mode (constant attenuation)

Volume +15dB to -79dB with 1dB step resolution soft-step control with programmable blend times

Bass second order frequency response center frequency programmable in 4 steps (60Hz/80Hz/100Hz/200Hz) Q programmable 1.0/1.25/1.5/2.0 DC gain programmable -15 to 15dB range with 1dB resolution

Middle second order frequency response center frequency programmable in 4 steps (500Hz/1KHz/1.5KHz/2.5KHz) Q programmable 0.5/0.75/1.0/1.25 -15 to 15dB range with 1dB resolution

Treble second order frequency response center frequency programmable in 4 steps (10KHz/12.5KHz/15KHz/17.5KHz) -15 to 15dB range with 1dB resolution

Speaker 4 independent soft step speaker controls, +15dB to -79dB with 1dB steps direct mute

Subwoofer single-ended mono output independent soft step level control, +15dB to -79dB with 1dB steps

Mute Functions direct mute digitally controlled SoftMute with 3 programmable mute-times(0.48ms/0.96ms/123ms)
