	GP_OP				2-wire serial		00h (OTP)
				OTP General Purpose Operational Amplifier Register
	Offset: 34h	Enables the opamp stages, defines opamp 2 mode and gain and sets the HP input multiplexer. This is
		a special register, writing needs to be enabled by writing 10b to Reg 3Fh first. This register is reset at
		POR and gets loaded with the OTP fuse contents.

5:2	OP2_OTP<3:0>	0000		R/W	Mode and volume settings for OP2, adjustable in 15 steps of 0.75dB
					0000: OP2L in inverting mode
					0001: 0 dB gain, OP2L in non inverting mode
					0001: 0.75 dB gain, non inverting
					..,
					1110: 9.75dB gain, non inverting
					1111:.10.5 dB gain, non inverting
1	OP2_ON	0		R/W	0: OP2 is switched off
					1: left OP2 is enabled
0	OPL_ON	0		R/W	0: OP1 is switched off
					1: OP1 is enabled
Table 35. OTP_SYS Register
	Name				Base		Default
	OTP_SYS				2-wire serial		40h (OTP)
					OTP System Settings Register
	Offset: 35h	Defines several system settings for OTP operation. This is a					special register, writing needs to be enabled
		by writing 10b to Reg 3Fh first. This register is reset at POR and gets loaded with the OTP fuse contents.
Bit	Bit Name	Default	Access			Bit Description
7	MAIN_LOCK	0		R/W	0: additional bits can be fused inside the OTP
					1: OTP fusing gets locked, no more changes can be done
6	TEST_BIT_3	1		R	for testing purpose only
5:4	MON_HP_MUX	00		R/W	Multiplexes the analog audio signal to HP amp in monitor mode
	<1:0>				00: MIC: selects QMICL/R output
					01: OP1: selects QOP1L/R outputs
					10:OP2: selects QOP2L/R output
					11: open: no signal mixed together with the line input signal
3:2	ILED_OTP<1:0>	00		W	Sets the current sunk into ILED

10 Application Information

Figure 33. AS3410 High Performance Application in Bridged Mode for High Impedance Headsets

For high impedance headphones two AS3410 can be used in a bridged mode each one driving one side of the headphone load as differential output to get 24mW output power per channel. Also the microphone inputs can be used in differential mode to reduce the noise level.
