2 / 16 page  TSL4531 DIGITAL AMBIENT LIGHT SENSOR TAOS112 − OCTOBER 2011 2 r r Copyright E 2011, TAOS Inc. The LUMENOLOGY r Company www.taosinc.com Detailed Description The device contains a photodiode array, an integrating analog-to-digital converter (ADC), signal processing circuitry, lux calculation logic, and an I2C serial interface on a single CMOS integrated circuit to provide lux data with a 16-bit output. No external circuitry is required for signal conditioning. The device features power management modes where the user can select continuous operation, power save mode in which the device inserts a power saving state between each acquisition, or single-cycle operation in which the device enters a power-down state after data acquisition. The device has three user-selectable integration times of 100 ms, 200 ms, or 400 ms, allowing the user to adjust the sensitivity of the device. Terminal Functions TERMINAL TYPE DESCRIPTION NAME NO. TYPE DESCRIPTION GND 2 Power supply ground. All voltages are referenced to GND. SCL 4 I I2C serial clock input terminal. SDA 3 I/O I2C serial data I/O terminal — bidirectional. VDD 1 Supply voltage.
