AD7195BCPZ-RL

Data Acquisition - Analog Front End (AFE)

AD7195BCPZ-RL is a high precision, 24-bit sigma-delta analog-to-digital converter (ADC) specially designed for high speed and accuracy measurements, mainly targeting Industrial and Medical applications. The converter offers the user high input impedance, low power consumption, excellent accuracy and linearity, low noise and ultra low distortion. The ADC has two main features: a data acquisition (AFE) and a power management controller.

Application Field and Working Principle

The AD7195BCPZ-RL provides a complete solution and can be used in a variety of applications, including industrial automation and medical diagnostics. The ADC has an on-chip AFE providing high impedance buffering of the analog input signals and configuration of the analog signal path. It has selectable gain options and programmable programmable offset cancellation that can be used to trim and match an analog interface. The ADC also has an on-chip temperature sensor that can be used to measure temperature or other conditions.

The ADC has an internal oscillator, which can be set to one of five frequencies, and a 12-bit ADC resolution. It also features a programmable internal reference voltage that can be set from 0 V to 5 V. The internal reference voltage can be used to compensate for different input voltage levels, by either boosting or reducing the signal. Finally, the ADC provides protection against input overvoltage, as well as power sequencing.

The ADC features an advanced sigma-delta modulator with an on-chip digital filter. With this advanced modulator, the ADC can provide high resolution and low noise performance. Data can be sampled at up to 78 kHz, giving the user an accurate picture of the data. The ADC can also perform digital calibration, which allows the user to adjust the offset, gain, and linearity of the ADC’s output. Finally, the ADC has an integrated temperature sensor, allowing the user to measure the temperature in their application environment.

The AD7195BCPZ-RL can be used in a wide variety of applications, including industrial, medical, automotive and consumer. The ADC has significantly increased accuracy, low power consumption and excellent performance, making it an excellent choice for many applications. With its advanced modulator, digital filter and internal reference voltage, the ADC is capable of providing application-level accuracy and precision.
