Low-Power Digital Ambient Light Sensor
with Enhanced Sensitivity
Integration Timer Bits (TIM[2:0])
The TIM[2:0] bits can be used to program the signal integration time.
In automatic mode (MANUAL = 0), integration time is automatically selected by the on-chip algorithm to be either
100ms/200ms/400ms/800ms. In manual mode, integration time can be varied by the user all the way from 6.25ms to
800ms. See Table 7.

0x03
Bits in Lux High-Byte register 0x03 give the 4 bits of exponent E3:E0 and 4 most significant bits of the mantissa byte
M7:M4, and represent the lux reading of ambient light. The remaining 4 bits of the mantissa byte M3:M0 are in the Lux
Low-Byte register 0x04 and enhance resolution of the lux reading from the IC.
Exponent (E[3:0]): Exponent bits of the lux reading (0000 to 1110). Note: A reading of 1111 represents an overrange
condition.
Mantissa (M[7:4]): Four most significant bits of mantissa byte of the lux reading (0000 to 1111).
Lux = 2 (exponent) x mantissa x 0.4
Exponent = 8xE3 + 4xE2 + 2xE1 + E0
Mantissa = 8xM7 + 4xM6 + 2xM5 + M4
A code of 0000 0001 calculates to be 0.4 lux.
A code of 1110 1111 calculates to be 98,304 lux.
A code of 1110 1110 calculates to be 91,751 lux.
Update of the contents of this register is internally disabled during I 2 C read operations to ensure proper data transfer
between internal ADC and I 2 C registers. Update of I 2 C registers is resumed when the master sends a STOP command.
If user wants to read both the Lux High-Byte register 0x03 and Lux Low-Byte register 0x04, then the master should
not send a STOP command between the reads of the two registers. Instead a REPEATED START command should
be used. This ensures accurate data is obtained from the I 2 C registers (by disabling internal updates during the read
process).
