8 / 33 page TSL2581, TSL2583 LIGHT-TO-DIGITAL CONVERTER TAOS134A − JULY 2012 7 The LUMENOLOGY r Company r r Copyright E 2012, TAOS Inc. www.taosinc.com PRINCIPLES OF OPERATION Analog-to-Digital Converter The TSL258x contains two integrating analog-to-digital converters (ADC) that integrate the currents from the channel 0 and channel 1 photodiodes. Integration of both channels occurs simultaneously, and upon completion of the conversion cycle the conversion result is transferred to the channel 0 and channel 1 data registers, respectively. The transfers are double buffered to ensure that invalid data is not read during the transfer. After the transfer, the device automatically begins the next integration cycle. Digital Interface Interface and control of the TSL258x is accomplished through a two-wire serial interface to a set of registers that provide access to device control functions and output data. The serial interface is compatible with I2C bus Fast-Mode. The TSL258x offers three slave addresses that are selectable via an external pin (ADDR SEL). The slave address options are shown in Table 1. Table 1. Slave Address Selection ADDR SEL TERMINAL LEVEL SLAVE ADDRESS GND 0101001 Float 0111001 VDD 1001001 NOTE: A read/write bit should be appended to the slave address by the master device to properly communicate with the TSL258x device. |
