LDC1314QRGHRQ1

The LDC1314QRGHRQ1 is a high-accuracy, ratiometric 24-bit ΔΣ Analog-to-Digital converter and Digital-to-Analog converter. It is designed for applications where slow-changing, low noise, and low distortion signals need to be processed.

Application Field:

The LDC1314QRGHRQ1 is designed for applications requiring the highest accuracy and low noise measurement of slow-changing signals. It is used in a wide range of markets such as healthcare, automotive, navigation, industrial, and communications. Its ratiometric ADC is particularly useful in automotive applications such as torque, pressure, and speed measurement. Its low-power dissipation makes it an attractive choice for many long-life products where power is at a premium, such as in medical and industrial applications.

Working Principle:

The LDC1314QRGHRQ1 uses a multi-stage delta-sigma modulator to convert analog signals into digital values. The first stage in the modulator is a low-pass filter which reduces the noise on the input signal. The filtered signal is then sampled and encoded by the internal 24-bit delta-sigma modulator. The result is a high-precision digital value which is sent to the DAC for output configuration. The DAC converts the digital values into analog signals according to its output configuration.

The device is unique in that its ADC can operate at low power consumption while still providing high accuracy. It also features an on-chip temperature sensor which allows the ADC to compensate for temperature changes. This ensures that calibration values don’t have to be adjusted over time to maintain accuracy. The temperature sensor also allows for better accuracy in applications that require performance within a wide temperature range.

The LDC1314QRGHRQ1 also features a differential analog-to-digital converter which can measure signals with high precision and low noise. This makes it ideal for use in environments where noise is a factor, such as in industrial and laboratory settings.

Conclusion:

The LDC1314QRGHRQ1 is a high-accuracy, ratiometric 24-bit ΔΣ Analog-to-Digital converter and Digital-to-Analog converter. It is designed for applications where slow-changing, low noise, and low distortion signals need to be processed. Its low-power dissipation and on-chip temperature sensor make it an attractive choice for many long-life products. The differential analog-to-digital converter also makes it ideal for use in noise-sensitive environments.
