Bit(s)
Function
Operation
D[7]
INV
Inverts the APC op-amp inputs.
When set to “0” the BIAS DAC
output is connected to the “+”input
and FB is connected to the “–” input
of the op amp. Set to “0” to use the
ADC feedback loop.
0 = emitter follower (no inversion);
1 = common emitter (inverted); read/write; non-volatile.
D[6]
GAIN
Sets the feedback voltage range by
changing the APCDAC output
swing; 0-V
REF
for optical feedback,
0-V
REF
/4 for electrical feedback.
1 = VREF/4 full scale;
0 = VREF full scale; read/write; non-volatile.
D[5]
BIASREF
Selects whether FB and VMPD are
referenced to ground or V
DD
and
selects feedback resistor termination
voltage (V
DDA
or GNDA).
1 = VDD; 0 = GND; read/write; non-volatile.
D[4:2]
RFB[2:0]
Selects internal feedback resistance.
(Resistors will be terminated to VDDA
or GNDA according to BIASREF.)

read/write; non-volatile.
D[1]
SRCE
V
BIAS
source vs. sink drive.
1 = source (NPN),
0 = sink (PNP); read/write; non-volatile.
D[0]
SPOL
Polarity of shutdown output, SHDN,
when active.
1 = high;
0 = low; read/write; non-volatile.

Default Value
1010 xxxxb = xxh (slave address = 1010xxxb)
Serial Address
A6h = 1010011b
Byte Address
2 = 02h
CAUTION: Changes to I2CADR take effect immediately! Any accesses following a write to I2CADR must be to the newly
programmed serial bus address. A valid OEM password is required for access to this register. This register is non-volatile and
will be maintained through power and reset cycles.
Bit(s)
Function
Operation
D[7:4]
I2CADR[3:0]
Upper four MSBs of the serial bus
slave address; writes take effect
immediately.
Read/write; non-volatile.
D[3:0]
LUTOFF
LUT offset. LUTOFF is added to the
result of the digital temperature
sensor to derive the table
index; writes take effect after reset.
Read/write; non-volatile.
