The LMP91300NHZJ is an analog front-end (AFE) device providing high-speed, high-accuracy, single-conversion acquisition and data conversion. The device supports both I2C/SPI and serial (UART) interface modes, providing a fast and convenient way to access, update and configure the device within system designs. It is designed to digitize and convert multiple analog signals (e.g. temperature, force, pressure, current, frequency, etc.) in both time-domain and frequency-domain applications. It is ideal for use in medical, industrial, automotive, security, aerospace and other applications.

The LMP91300NHZJ supports up to 8-channel simultaneous sampling of single-ended, differential and offset-shifted differential input signals. The device is also able to perform bi-directional communication with extended peripheral devices. Its highly programmable architecture, allowing for flexibility in different system designs, covers a wide range of data acquisition and conversion needs.

This versatile analog front end offers several features which make it well-suited to a variety of applications. Firstly, the device is highly accurate, with an onboard 24-bit sigma-delta converter that measures signals with up to 16-bit accuracy. Secondly, its versatile architecture enables it to be used with a wide range of peripherals, including I2C, SPI, UART and PWM interfaces. Thirdly, the low on-chip noise and low power consumption reduce the power requirements of the system and make it more energy efficient.

The working principle of the LMP91300NHZJ is based on the principle of analog-to-digital conversion. When an analog signal is measured, a digital output is generated, which is then stored for later use. The device uses a system of programmable settings to determine how the analog input signal is converted into its digital form, allowing for a wide range of accuracy and flexibility.

The device consists of an analog input, sigma-delta converter, switching circuits, control and communication interface circuits and several other components. The analog input is first processed by the sigma-delta converter, which converts the analog input into a pulse-width (PWM) output. The PWM output is then further converted into a digital output using the programmable settings. Next, the control and communication interface circuits are used to enable the device to communicate with other peripherals and transfer the digital output data. Finally, the digital output is stored in one of the device’s internal registers.

The LMP91300NHZJ is an ideal choice for users who require high-speed, high-accuracy analog-to-digital conversion for commercial and industrial systems. It is highly programmable, cost-effective and power-efficient, making it suitable for applications such as precision control, test and measurement, medical, industrial and automotive applications. It offers a wide range of features and programming options that enable users to make the most of their data acquisition and conversion needs.
