APDS-9700 Signal Conditioning IC for Optical Proximity Sensors Data Sheet Description Features APDS-9700 is a signal conditioning IC that enhances the Low power consumption performance and robustness of the optical sensors used LED pulse width control for proximity or object detection. Low shut down current APDS-9700 is a single chip solution that consists of a LED External LED drive-current control driver circuit, sunlight cancellation and built-in LED stuck Complete shutdown mode high protection circuit integrated into a single chip. APDS- 9700 has articial light immunity and is also operational Supply voltage : 2.4 V to 3.6 V under the sun. Design exibility is optimized as APDS- Operational in sunlight conditions up to 100klux(with 9700 can be paired up with an integrated proximity sen- HSDL-9100) sor or discrete pair solution. Articial light immunity APDS-9700 can be disabled to maximize power savings Analog & Digital output available and battery life in applications such as portable or bat- tery-operated devices. The LED current of the optical Built in hysteresis comparator for digital output proximity sensors can be congured to dierent levels LED stuck High protection using a limiting resistor at the LEDA pin.
