MLX90614 General Description

The MLX90614 is an Infra Red thermometer for non contact temperature measurements. Both the IR sensitive thermopile detector chip and the signal conditioning ASIC are integrated in the same TO-39 can.
Integrated into the MLX90614 are a low noise amplifier, 17-bit ADC and powerful DSP unit thus achieving high accuracy and resolution of the thermometer.

The thermometer comes factory calibrated with a digital SMBus output giving full access to the measured temperature in the complete temperature range(s) with a resolution of 0.02°C.

The user can configure the digital output to be PWM. As a standard, the 10-bit PWM is configured to continuously transmit the measured temperature in range of -20 to 120 °C, with an output resolution of 0.14 °C.

    PAM8403 Amplifier Kelas D

    Deskripsi

    The PAM8403 is a 3W, class-D audio amplifier. It offers low THD+N,
    allowing it to achieve high-quality sound reproduction. The new
    filterless architecture allows the device to drive the speaker directly,
    requiring no low-pass output filters, thus saving system cost and PCB
    area.
    With the same numbers of external components, the efficiency of the
    PAM8403 is much better than that of Class-AB cousins. It can extend
    the battery life, which makes it well-suited for portable applications.
    The PAM8403 is available in SOP-16 package.

    Feature

    • 3W Output at 10% THD with a 4Ω Load and 5V Power Supply
    • Filterless, Low Quiescent Current and Low EMI
    • Low THD+N
    • Superior Low Noise
    • Efficiency up to 90%
    • Short Circuit Protection
    • Thermal Shutdown
    • Few External Components to Save the Space and Cost
    • Pb-Free Package

    Aplikasi

    • LCD Monitors / TV Projectors
    • Notebook Computers
    • Portable Speakers
    • Portable DVD Players, Game Machines
    • Cellular Phones/Speaker Phones
