Si1151 & Si1152 Proximity/Ambient Light Sensors

Silicon Labs Si1151 and Si1152 Proximity/Ambient Light Sensors combine an ambient light sensor, a proximity sensor, and a gesture detector into a compact, single-chip solution. The low-power, long-range Si1151 and Si1152 sensors feature an I²C digital interface and programmable-event interrupt output. These touchless sensor ICs include dual 23-bit analog-to-digital converters, an integrated high-sensitivity array of visible and infrared photodiodes, a digital signal processor, and one (Si1151) or two (Si1152) integrated LED drivers with programmable drive levels.
