The AD1674BRZ is a 14 bit, 150 kSPS, 0.125 ms latency, 5 MSPS, low-noise enhanced precision SAR A/D converter from Analog Devices. It allows for precise, low noise, low power data acquisition at single or multiple channels. It has a very low noise floor and allows for one of the widest analog input ranges in the data acquisition industry. The AD1674BRZ is ideal for data acquisition applications such as sensors, instruments and devices.

The AD1674BRZ is available in a variety of packages, including a 64-pad thermal LQFP and a small 3mm VFQFN package. It has on-chip features such as a digital low pass filter to eliminate unwanted noise, a low noise input track and hold buffer, and a low noise charge pump with a speed multiplier. It also features high performance differential/single-ended inputs, high sampling rate and low latency, as well as wide bandwidth digital control.

The AD1674BRZ application field includes medical, industrial, consumer and aerospace applications. The medical applications include patient monitoring, medical imaging and recording. The industrial applications include industrial process control, pressure sensing and temperature sensing. The consumer applications include motion detection, electrostatic measurement and home security systems. And finally, the aerospace applications include supersonic flight control and monitoring, as well as guidance system monitoring.

The working principle of the AD1674BRZ is based on its ability to rapidly and precisely convert analog input signals into digital signals. It utilizes Sigma-Delta Conversion technique to convert analog signals into digital signals with very low noise. The input to the A/D converter is an analog signal that is amplified and then ‘sampled’. Next, the signal is converted by a low noise track and hold amplifier, and then further amplified. The signal is then converted to a digital equivalent using the Sigma-Delta Conversion technique and then converted to a digital data form using successive approximations. The output of the AD1674BRZ is then sent to the user device.

In conclusion, the AD1674BRZ is a high performance A/D converter from Analog Devices. It offers precise, low noise, low power data acquisition in a variety of package styles, such as a 64-pad thermal LQFP and a small 3mm VFQFN package. It can be used for a variety of applications, including medical, industrial, consumer, and aerospace. Finally, it works on the principle of Sigma-Delta Conversion technique to convert analog signals into digital signals with very low noise.
