ASEK1454KLE-BB-T

ASEK1454KLE-BB-T evaluation board is mainly suitable for designing, testing, and optimizing sensor applications. This board consists of two essential components, namely a signal conditioner IC and Bosch\'s low-power BMP280 environmental digital pressure sensor. The evaluation board is ideally suitable for low-power and small footprint applications due to its simplicity.

The signal conditioner IC in the ASEK1454KLE-BB-T consists of two signal conditioning elements which are sequential in nature. The first stage comprises of an over-sampling amplifier and low-pass filter that condition the sensor’s output signals. The over-sampling amplifier is optimized to reduce noise and ensure a low differential input range, while the low-pass filter is designed to provide the required high frequency shaping. The output of the over-sampling amplifier and low-pass filter is then delivered to the second stage, which consists of an analog-to-digital converter and a digital-to-analog converter (DAC) that is used to digitally set the output voltage.

The BMP280 digital pressure sensor integrated in the ASEK1454KLE-BB-T features a very low power consumption, with a minimum power consumption of 0.2µA in the sleep mode, and a wide operating range of 2.7V to 3.6V. This sensor has a resolution of 0.1mbar, which makes it suitable for a wide range of sensor applications such as pressure sensing, flow sensing, thermometry, altitude sensing, building pressure sensing etc. The sensor’s small footprint and integrated features make it suitable for portable and handheld applications.

The principal function of the ASEK1454KLE-BB-T evaluation board is to provide a platform for analyzing, testing and optimizing sensor applications with low power consumption and reduced footprint. The board also serves as an efficient tool for end-users to evaluate and validate the performance of the Bosch BMP280 digital pressure sensor. The ASEK1454KLE-BB-T evaluation board features an onboard USB^2.0 connection and demo software for easy control, monitoring and communication with the sensor. The board also comes with a CD containing detailed documentation and source code for seamless setup and testing.

In summary, ASEK1454KLE-BB-T is an ideal evaluation board for applications such as pressure sensing, thermometry, altitude sensing and others. The board also enables users to evaluate and validate the performance of the Bosch BMP280 digital pressure sensor with its simplified features and low power consumption. Moreover, the onboard USB connection and demo software make it easier for users to control, monitor and communicate with the sensor.
