PT2358 Datasheet | PTC

DESCRIPTION The PT2358 is a multiple inputs audio processor designed for Car Audio purpose. Using I2C interface controls all of the functions. Thanks for highly integration most of peripheral sub-circuits and ponents, it provides up to 9 inputs and equips outputs includes front, rear channel outputs. For highly enhanced audio performance and experience, PT2358 volume controller has Soft-Step function to eliminate click noise during volume step changes. Adjustable input gain, adaptive loudness, subwoofer filter, treble and bass tone control are all included. APPLICATIONS - Car Audio FEATURES - Operation voltage 6~10V - 7 single-ended stereo Inputs - 1 quasi-differential (QD) input for AUX - 1 fully-differential (FD) input for Bluetooth® audio module. - Input gain from 0 ~+15d B in 1d B step - Main volume gain from +15 to -79d B in 1d B step with Soft-Step function. - Soft-Mute and Soft-Step function for preventing audible click during volume and sources changing. - 1 subwoofer output with 3-band crossover frequency selection and gain from +15 to -79d B in 1d B step - Tone Control (Bass and Treble): -15 to +15d B in 1d B step - Loudness: gain from 0 to -15d B in 1d B step - Mixing input with 50% mixing ratio for front speakers, gain from -79 to +15d B in 1d B step. - 4 independent outputs for front and rear speakers, output gain from +15 to -79d B with 1d B step - Controlled by I²C Interface - Low Distortion and Low Noise - 48-pin LQFP package Tel: 886-66296288‧Fax: 886-29174598‧http://.princeton..tw‧2F, 233-1, Baociao Road, Sindian Dist.,New Taipei City 23145, Taiwan BLOCK DIAGRAM MIXIN SE7L SE6L SE5L SE4L SE3L SE2L SE1L FDL+ FDL- FDRFDR+ QDL QDG QDR FDL L FDR R QD R SDA CONTROL SE7R SE6R SE5R SE4R SE3R SE2R SE1R IN GAIN LOUDNESS SOFT-MUTE MASTER VOLUME BASS TREBLE IGL VOL...
