Data Acquisition - ADCs/DACs - Special Purpose: CS53L21-CNZ Application Field And Working Principle

The CS53L21-CNZ is a special purpose analog-to-digital converter (ADC) designed for very low power applications. It is designed for sensor reading applications, including applications where power is limited, such as in wireless sensors, and applications that require extremely low power, such as in medical implants. It is also suitable for applications where the ADC has to operate over a wide range of temperatures or in harsh environments. It is offered in multiple versions, with the highest performance version delivering a best-in-class power efficiency and noise performance.

The CS53L21-CNZ features a 24-bit SAR ADC, a lower noise programmable gain amplifier (PGA), an analog input multiplexer and an integrated temperature compensation circuit. It can sample at rates up to 800 kilosamples per second (ksps) and can support a wide range of input voltages. It has an input voltage range of 0V to 3.3V, and can also support an optional negative voltage rail for expanded input voltage range. The device also has an internal reference and programmable offset calibration, which simplifies the board design.

The CS53L21-CNZ supports various interfacing modes and can be used with a variety of sensors. For example, for sensor applications requiring low power, the low power mode is used. In this mode, the device can operate as low as 8mW. The device also supports an I²S interface for high speed applications. The I²S interface supports data rates up to 800 ksps, making it ideal for high speed applications such as ultrasound imaging and motor control.

The CS53L21-CNZ can also be used in applications requiring extended temperature range, or in harsh environmental conditions. The device offers an integrated temperature sensor, which supports measuring temperatures of up to –40°C to +105°C. The device also has an operating voltage range of 2.7V to 5.5V, making it suitable for applications such as automotive, industrial, and medical systems.

The device features a 24-bit pipeline analog-to-digital converter (ADC) with an integrated programmable gain amplifier (PGA). The PGA has a maximum gain of 8 and a programmable input range of 0V to 3.3V. The PGA also offers low noise gain settings and adjustable noise filtering, making it ideal for sensor reading applications. The device also has an integrated quantifier and temperature compensation circuit, which allows the device to accurately convert a wide range of input voltages and allows it to operate over a wide temperature range.

The CS53L21-CNZ also features a low power consumption mode, where the device can operate on as little as 8mW. This makes it ideal for low power applications such as wireless sensors and medical implants. The device supports low power modes such as low power standby and power down modes, allowing for even further power savings. It also supports a programmable clock frequency, allowing the user to select the desired update rate and reduce power consumption.
