- If R/W
= 1, the Power Amplifier Sends Four Diagnostics Bytes, DB1, DB2, DB3 and DB4:
DB1 Diagnostic Byte:
Bit
D7
Thermal warning active (D7
= 1)
D6
Diag not actived or not terminated (D6
= 0)
Diag terminated (D6
= 1)
D5
Channel 1 current detection
Output peak current
< 250 mA (IB2 D7 = 0) open load (D5 = 1)
Output peak current
< 100 mA (IB2 D7 = 1) open load (D5 = 1)
Output peak current
> 500 mA (IB2 D7 = 0) normal load (D5 = 0)
Output peak current
> 300 mA (IB2 D7 = 1) normal load (D5 = 0)
D4
Channel 1
Turn-on diagnostic (D4
= 0)
Permanent diagnostic (D4
= 1)
D3
Channel 1
Normal load (D3
= 0)
Short load (D3
= 1)
D2
Channel 1
Turn-on diag: No open load (D2
= 0)
Open load detected (D2
= 1)
Offset diag: No output offset (D2
= 0)
Output offset detected (D2
= 1)
D1
Channel 1
No short to VCC (D1 = 0)
Short to VCC (D1 = 1)
D0
Channel 1
No short to GND (D0
= 0)
Short to GND (D0
= 1)
