The CS53L21-CNZR belongs to a special category of Data Acquisition, ADCs/DACs, and is part of the Analog Devices family of components. It is a two-channel, low-noise, low-power data acquisition device that is often used in applications where high dynamic range and low noise are required. The CS53L21-CNZR is a CMOS integrated circuit that combines a 48 dB preamplifier, a differential data converter, and an analog-to-digital converter (ADC) on a single die. Its high performance and low power consumption make it an attractive device for a variety of applications, from portable medical and industrial instrumentation to automotive systems and safety-critical systems.

The CS53L21-CNZR application field and working principle is based on a two-channel data converter design providing a 48dB gain and low offset and drift in the analog-to-digital (ADCs/DACs) stage. The gain and offset adjustment can be set externally by the use of an on-chip register programming.

The differential preamplifier inside the CS53L21-CNZR offers low noise and wide dynamic range performance with a gain of 44dB and a very low drift of 6db/°C. The preamplifier inputs are accessible internally and externally, allowing for higher gain, higher accuracy, and improved signal-to-noise ratio.

The differential data converter provides another 24dB gain and is incorporated on chip. This ensures a high signal-to-noise ratio and makes the CS53L21-CNZR ideal for use in precision measuring systems, such as ECG and sonar.

The A/D converter provides 12-bit resolution; the differential input and full load rejection, as well as its wide linearity and excellent SNR performance, makes it very suitable for medical, industrial and automotive applications. The A/D converter can be programmed to different sample rate, and analogue input range, allowing it to fit a wide range of applications.

In addition, the CS53L21-CNZR is highly configurable and flexible, as it supports a variety of programming and control options. The on-chip registers can be programmed to accommodate different gain settings, offset adjustments and operating modes. This helps to avoid complex hardware design, thus reducing cost and development time.

The CS53L21-CNZR is an ideal choice for applications requiring low noise, high dynamic range and low power consumption. Its combination of a preamplifier, differential data converter, andanalog-to-digital converter, makes it a great fit for applications such as portable medical and industrial instrumentation, automotive systems and safety-critical systems.
