Description
The AK9723AD is an analog front-end IC for IR sensors with a built-in LED driver for infrared emission. The AK9723AD has a light emitting element (IR - LED) driver with a programmable constant current circuit, which enables suitable control according to the optical path length of the gas sensor. In addition, the signal from the light receiving element (IR sensor) is amplified by a programmable gain amplifier, A / D Converted with 13-bit resolution, and performed via the I²C bus. Each setting can be performed from an external MCU. By connecting our products AK9710ADF01 and AK9700AD, you can easily configure NDIR type CO₂ sensor system.
Key Features
It has a built-in LED driver. The light emitting device (IR - LED) driver can be controlled according to the optical path length of the gas sensor with a programmable constant current circuit.
Applications
Measurement of gas concentration in a room or in a closed chamber
