STA335W

2.0-channel high-efficiency digital audio system

Features

■ Wide voltage supply range

– 5 V to 26 V (operating range)

– 30 V (absolute maximum rating)

■ 2 channels of ternary PWM (stereo mode) (2 x

20 W into 8

Ω at 18 V)

■ 2.0 channels of 24-bit FFX 100 dB SNR and

dynamic range

■ Selectable 32 to 192 kHz input sample rates

■ I2C control with selectable device address

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

0.5 dB/step resolution

■ Soft volume update with programmable ratio

■ Individual channel and master gain/attenuation

■ Individual channel and master soft/hard mute

■ Automatic zero-detect mute

■ Automatic invalid input-detect mute

■ 2-channel I2S input data interface

■ Advanced AM interference frequency

switching and noise suppression modes

■ Selectable high- or low-bandwidth

noise-shaping topologies

■ Variable max power correction for lower

full-power THD

■ Selectable clock input ratio

■ 96 kHz internal processing sample rate, 24 to

28-bit precision

■ Thermal overload and short-circuit protection

embedded

■ Video apps: 576 x Fs input mode supported

■ Fully compatible with STA335BW (on the

common registers).
