Note that the last 4 bits are the status register.
TOUT
Read access: Directly from internal register.
Write access: Directly to internal register in test mode.
This register keeps the linearised ambient temperature. (Tambient)
Register format:
D11..D0 :
OVH:
OVL:
FE:

Note that the last 4 bits are the status register. These bits are identical to the last 4 bits of the IROUT
register.
IRDATA
Read access: Directly from internal register.
Write access: Directly to internal register in test mode.
This register keeps the measured IR data, compensated with the current offset of the amplifier (stored in
Iros register).
TDATA
Read access: Directly from internal register.
Write access: Directly to internal register in test mode.
This register keeps the measured Temp data, compensated with the current offset of the Temp amplifier
(stored in Tos register).
IROS
Read access: Directly from internal register.
Write access: Directly to internal register in test mode.
This register keeps the offset of the IR amplifier. Each measurement from IR amplifier will be
compensated with this offset.
TOS
Read access: Directly from internal register.
Write access: Directly to internal register in test mode.
This register keeps the offset of the Temp amplifier. Each measurement from Temp amplifier will be
compensated with this offset.
