The AD7655ACPZ-RL is an analog-to-digital converter (ADC) device manufactured by Analog Devices. It is part of the company\'s Data Acquisition - Analog to Digital Converters (ADC) product family. The AD7655 is a high-speed, high-resolution, low-power, 14-bit analog-to-digital converter with a wide range of features, making it ideal for many applications, including test, instrumentation, medical, and industrial.

The AD7655 takes advantage of a proprietary digital signal processing (DSP) technique to obtain 14-bit resolution in a very small package. The device has an integrated digital signal processor (DSP), which allows it to sample at speeds up to 1MSPS (mega samples per second). The advanced architecture of the device allows it to provide excellent performance in terms of dynamic range, linearity, and noise. Additionally, the device is capable of settling the output to within +/-1 LSB (Least Significant Bit) within 10 clock cycles.

The AD7655ACPZ-RL comes in a ceramic 28-pin Pb-free, RoHS-compliant, surface-mount TSSOP-28 package that can be mounted directly onto a PCB. In addition to the 14-bit resolution, the device has two differential inputs with programmable gains, an onboard sample-and-hold circuit, and a serial port for communications. The device also provides an on-chip temperature sensor, DNLer (Differential Nonlinearity Error) indication, and a one-shot autocalibration sequence.

The AD7655ACPZ-RL is a high-speed data acquisition system suited for a wide range of applications. It is ideal for medical, instrumentation, and industrial applications that require high-quality measurements with low power consumption. The device is designed for high-speed sampling and accuracy over temperature variations, with a dynamic range of better than 30dB. Additionally, its high-resolution capabilities make it an excellent choice for applications such as acquiring ECG signals, scanning sonography, vibration monitoring, and other medical/scientific measurements.

The device also has excellent dynamic performance, with a gain error of less than ±0.25dB and a total harmonic distortion (THD) of < 0.02%. The device\'s low power consumption of approximately 150mW reduces the system power budget, making it suitable for battery-powered applications. In addition, the device\'s low EMI (electromagnetic interference) emission makes it ideal for a variety of applications where low emissions are essential.

One of the key features of the AD7655ACPZ-RL is its enhanced integration. This allows for the integration of complex peripherals such as SPM pulse generators and digital interfaces within a single device. This reduces board space, reduces cost, and enhances system performance. Additionally, the device has a built-in temperature sensor and differential nonlinearity (DNL) indication, making it suitable for applications that require high-accuracy measurements over temperature variations.

In summary, the AD7655ACPZ-RL is a high-speed, high-resolution, low-power 14-bit analog-to-digital converter from Analog Devices. It is ideal for a wide range of medical, instrumentation, and industrial applications that require accurate measurement, low power consumption, and high speed. The device features a built-in temperature sensor, differential nonlinearity (DNL) indication, and an onboard sample-and-hold circuit. Additionally, it offers an extended integration capability, allowing for SPM pulse generation and digital interfaces.
