The ADPD2211ACPZ-R7 from Analog Devices Inc is an optical ambient light sensor that is used in optical sensing applications. It has an infrared (IR) filter and an ultraviolet (UV) filter and is designed for applications such as consumer light sensing and industrial light sensing. It is a highly integrated device that features various low-noise components and reduced EMI emissions in comparison to discrete solutions.

The ADPD2211ACPZ-R7 is a bipolar ambient light sensor that utilizes an on-chip, low-noise, low-power, IR receiver combined with a zero bias gate FET transistor to measure the IR intensity of any ambient light source. The device has a 10 mm2 sensing area of light and is capable of providing accurate and precise data in a wide range of lighting conditions including direct sunlight. It is also well-suited for applications that require low-power consumption. The device includes built-in safety safeguards, which protect the device from high-voltage transients, electrostatic discharges, and power surges.

The working principle of the ADPD2211ACPZ-R7 is based on an integrated optical sensing circuit. The IR receiver detects the radiation of any ambient light source through the IP filter, and the FET transistor provides the necessary voltage for the operation of the sensor. The IR receiver then converts the detected optical radiation into a voltage signal that is proportional to the incident radiation. This signal is then processed by the ADPD2211ACPZ-R7 and is used to calculate the light intensity value. The output voltage of the device is proportional to the light intensity value.

The spectrum sensitivity of the ADPD2211ACPZ-R7 sensor is between 400nm to 1100nm. The infrared filter can be used to select any spectral range from this range for a more accurate and precise measurement. The device also offers excellent temperature stability, with a maximum temperature coefficient of 0.015%/°C. The ADPD2211ACPZ-R7 has a wide operational temperature range of −40°C to +80°C. It is also extremely low-power and requires only 10 µA in operational mode.

The ADPD2211ACPZ-R7 is designed for a wide range of applications, including consumer lighting products, automotive lighting and HVAC systems, smartphones and tablets, medical devices and systems, home/security/facility automation, and anywhere else where accurate and reliable light sensing is required. The device can also be used in situations where space is limited or energy consumption is an issue, such as automotive and consumer lighting.

The ADPD2211ACPZ-R7 is part of Analog Devices’ family of optical sensors, which are designed to provide precise, accurate, and reliable measurements of light intensity in various applications. These sensors are designed to provide low power consumption and efficient performance in a wide range of environmental conditions. The ADPD2211ACPZ-R7 is an excellent choice for any application where optical sensing is a requirement. It is a highly integrated device that provides reliable operation and is a cost-effective solution for any optical sensing application.
