A write to OEMCFG1 will result in any A/D conversion in progress being aborted and the result discarded. The A/D will begin a
new conversion sequence once the write operation is complete.
All bits in OEMCFG1 are non-volatile and will be maintained through power and reset cycles. A valid OEM password is
required for access to this register.
Bit(s)
Function
Operation
D[7]
INV
Inverts the APC op-amp inputs.
When low, the BIAS DAC output is
connected to the “+”input and FB is
0 = emitter follower (no inversion);
1 = common emitter (inverted); read/write; non-volatile.
connected to the “–” input of the op
amp. Set low to use the APC
feedback loop.
D[6]
GAIN
Sets the feedback voltage range by
changing the APCDAC output
swing; 0-V REF for optical feedback,
1 = V REF /4 full scale;
0 = V REF full scale
0-V REF /4 for electrical feedback.
D[5]
D[4:2]
BIASREF
RFB[2:0]
Selects whether FB and VMPD are
referenced to ground or V DD and
selects feedback resistor termination
voltage (V DDA or GNDA).
Selects internal feedback resistance.
Resistors will be terminated to V DDA
or GNDA according to BIASREF.
1 = V DD ; 0 = GNDA
If this bit is set to 0, bit 1 should be set to 1
If this bit is set to 1, bit 1 should be set to 0

101 = 12.8k ?
110 = 25.6k ?
111 = 51.2k ?
D[1]
SRCE
V BIAS source or sink drive.
1 = source (NPN): bit 5 should be set to 0.
0 = sink (PNP): bit 5 should be set to 1.
D[0]
July 2010
SPOL
Polarity of the shutdown output,
SHDN, when active.
1 = SHDN is active-high
0 = SHDN is active-low
