AD7450ABRM-REEL7 performance is also suitable for industrial control, process control, and medical instrumentation. With its small size, high-density PSPCM package form factor, and low-power operation, the AD7450ABRM-REEL7 is an excellent choice for a wide variety of applications.

Working Principle

The AD7450ABRM-REEL7 is an integrated circuit (IC) of an Analog-to-Digital Converter (ADC) composed of a low-frequency voltage to frequency converter (VFC) and two low-power, low-noise CMOS differential amplifiers (ADCs). The VFC core comprises the comparator, timer, and output gating logic that provide the timing and logic control of the ADC\'s operation. The two low-power, low-noise CMOS differential amplifiers (ADCs) are integrated into the VFC core to measure the differential signal out of the differential input. Due to the integration of the amplifiers, the device can operate over a wide-range of frequencies, allowing the ADC to have fast acquisition times, reducing the amount of time required for signal settling and overall measurement time. The output of the ADC is a digital signal, which is converted to a digital format with 14-bit or 16-bit resolution.

Performance

The AD7450ABRM-REEL7 is a high-performance ADC with excellent linearity, accuracy, and fast settling time. It includes a wide-range of features and performance capabilities such as low power signal processing, low input offset voltage, wide dynamic range, low noise, and very fast conversion. The AD7450ABRM-REEL7 is capable of measuring up to ±2 LSB INL B accuracy and can provide up to 10-bit resolution. It also features a low power operation (1.2 mW at 3V) and low input offset voltage (7 μV). Furthermore, the AD7450ABRM-REEL7 also has a wide dynamic range of 80 dB and a very fast conversion time of 10 μs.

In summary, the AD7450ABRM-REEL7 is an integrated circuit (IC) of a low-cost Analog-to-Digital (ADC) Converter with excellent linearity and accuracy, fast settling time, and low-power operation, making it a great choice for a wide range of applications. It is capable of measuring up to ±2 LSB INL B accuracy and has a wide dynamic range of 80 dB, as well as a wide-range of features such as low offset voltage, low noise, and very fast conversion. As a result, the AD7450ABRM-REEL7 is a highly desirable ADC for a range of industries and applications.
