STA339BWS

2.1-channel 40-watt high-efficiency digital audio system

Sound Terminal^®

Features

■ Wide-range supply voltage, 4.5 V to 21.5 V

■ Three power output configurations:

– 2 channels of ternary PWM

(2 x 20 W into 8 Ω at 18 V) + PWM output

– 2 channels of ternary PWM

(2 x 20 W into 8 Ω at 18 V) + ternary stereo

line-out

PowerSSO-36

with exposed pad down (EPD)

– 2.1 channels of binary PWM (left, right,

LFE) (2 x 9 W into 4 Ω +1 x 20 W into 8 Ω

at 18 V)

■ Independent channel volume and DSP bypass

■ I S input data interface

■ Input and output channel mapping

■ FFX with 100-dB SNR and dynamic range

■ Scalable FFX modulation index

■ Automatic invalid input-detect mute

■ Up to 8 user-programmable biquads/channel

■ Three coefficient banks for storing EQ presets

■ Selectable 32- to 192-kHz input sample rates

■ I C control with selectable device address

with fast recall via I C interface

■ Digital gain/attenuation +48 dB to -80 dB with

■ Bass/treble tones and de-emphasis control

■ Selectable high-pass filter for DC blocking

0.5-dB/step resolution

■ Soft volume update with programmable ratio

■ Individual channel and master gain/attenuation

■ Two independent DRCs configurable as a

■ Advanced AM interference frequency

switching and noise suppression modes

■ Selectable high- or low-bandwidth

dual-band anticlipper (B DRC) or as

noise-shaping topologies

independent limiters/compressors

■ Selectable clock input ratio

■ EQ-DRC for DRC based on filtered signals

■ Dedicated LFE processing for bass boosting

■ 96-kHz internal processing sample rate

■ Thermal overload and short-circuit protection

■ Audio presets:

technology
