Burr Brown PCM and TAS chips

Filter is applied to PCM samples at oversampling stage just prior to sigma-delta modulator.
Playback is automatically restarted to make filter change effective.
NOTE: Filter is bypassed if sample rate is 384 kHz.
Analog gain can be set to 0 dB (2-Vrms) or –6 dB (1-Vrms).
Analog gain boost can be set to 0 dB (normal amplitude) or .8 dB (10% boosted amplitude).

Allo Piano 2.1 (Dual PCM5142)

Dual-Mono: main DAC outputs L ch and Sub DAC outputs R ch (L/mute mute/R).
Dual-Stereo: both DAC's output L/R channels (L/R L/R).
Stereo: all freq to Main L/R, Sub L/R muted
Subwoofer: 2.1/2.2 (high freq to Main L/R, low freq to Sub L / Sub L/R)
 Hz Frequency range: 60 - 200 Hz.
% Volume range: 0 - 100%.

MERUS(tm) Amp piHAT ZW

The MA12070P provides different power mode profiles for operating the internal power amplifiers. They define optimal settings of the amplifier for the intended application. The power mode profile selection affects various parameters such as switching frequency, modulation scheme and loop-gain, thus providing flexibility in design tradeoffs such as audio performance, power loss and EMI.
