TDA8593J
I2C-bus controlled 4
× 45 W power amplier
Table 5:
Instruction byte IB1
Bit
Description
D7 to D2
-
D1
AC or DC-load detection switch
0 = AC or DC-load detection off; resets DC-load detection bits and AC-load
detection peak current counter
1 = AC or DC-load detection on
D0
amplier start enable (clear power-on reset ag, D7 of DB2)
0 = amplier off; pin DIAG remains LOW
1 = amplier on; when power-on occurs, bit D7 of DB2 is reset and pin DIAG is
released
Table 6:
Instruction byte IB2
Bit
Description
D7 to D2
-
D1
soft mute all amplier channels (mute delay 20 ms)
0 = no mute
1 = mute
D0
hard mute all amplier channels (mute delay 0.4 ms)
0 = no mute
1 = mute
Table 7:
Instruction byte IB3
Bit
Description
D7
clip detection level
0 = 3 % detection level
1 = 1 % detection level
D6
amplier front channels gain select
0 = 26 dB (normal mode)
1 = 20 dB (line driver mode)
D5
amplier rear channels gain select
0 = 26 dB (normal mode)
1 = 20 dB (line driver mode)
D4
amplier thermal protection pre-warning
0 = warning level on 145
°C
1 = warning level on 122
°C
D3
disable RF channel
0 = RF channel enabled
1 = RF channel disabled
D2
disable LF channel
0 = LF channel enabled
1 = LF channel disabled
