10 / 42 page Electrical specification STA333W 10/42 SNR Signal to noise ratio in ternary mode A weighted 100 dB Signal to noise ratio in binary mode A weighted 90 PSRR Power supply rejection ratio DXX stereo mode, < 5 kHz, Vripple = 1 V RMS audio input = dither only 80 dB XTALK Crosstalk DXX stereo mode, < 5 kHz, One channel driven at 1 W the other channel measured 80 dB η Peak efficiency in DXX mode Po = 2 x 20 W into 8 Ω 90 % 1. The ILIM data is for 1 channel of BTL configuration, thus, 2 x ILIM drives the 2-channel BTL configuration. The current limit is active when OCRB = 0 (see Table 24: Over current warning detect adjustment bypass on page 26. When OCRB = 1 then ISC applies. 2. The ISC current limit data is for 1 channel of BTL configuration, thus, 2 x ISC drives the 2-channel BTL configuration. The short-circuit current is applicable when OCRB = 1 (see Table 24: Over current warning detect adjustment bypass on page 26. Table 6. Electrical characteristics (continued) (VCC = 18 V, VDD = 3.3 V, fsw = 384 kHz, Tamb = 25° C, RL = 8 Ω unless otherwise specified) Symbol Parameter Conditions Min. Typ. Max. Unit |
