ISLA224S20IR1Z

ISLA224S20IR1Z is a low power, high speed analog to digital converter (ADC) from Intersil Corporation.

It has a low power, single-ended CMOS micro-controller interface, analog input with resolution of 10-bit plus sign, integrated voltage reference, and an onboard temperature sensor. Output type can be configured as a serial peripheral interface (SPI), serialized LVDS, or pulse width modulation (PWM).

ISLA224S20IR1Z is ideal for noise-sensitive, low power medical and industrial applications including pulse oximetry, ECG monitoring, power line transducers, and environmental sensing. This device is a perfect choice for any low power monitoring and control applications which require the highest level of accuracy.

Application Field:

The ISLA224S20IR1Z is a particularly well-suited ADC for any noise sensitive, low power environments such as medical and industrial. It can be used for pulse oximetry, ECG machine monitoring, and monitoring power line transducers. The on-board temperature sensor also helps in providing a precision temperature measurement for environmental sensing.

The ISLA224S20IR1Z is also suitable for noise-sensitive data acquisition and control applications which require a high level of accuracy. It can be used to accurately capture analog signals and quickly convert them into digital signals. Furthermore, its low power consumption makes it ideal for battery powered systems.

Working Principle:

The working principle of the ISLA224S20IR1Z is based on pulse width modulation (PWM) technique. In PWM, an analog output signal is converted into a series of digital bits. Each bit is represented by a pulse of a certain width. The width of the pulse is adjusted to correspond to the level of the input signal.

During operation, the device first converts the analog signal into a 10-bit value by sample and hold function. The device then proceeds to convert this value into a digital bits stream by using its PWM module. The bit stream is then sent to the output as either a serial peripheral interface (SPI) or serialized LVDS.

In pulse oximetry application, for example, a light detector is used to measure light intensity from a pulsing source. The light intensity is then converted into a 10-bit value by ISLA224S20IR1Z and transmitted to the output. The device can also be used to measure the level of other parameters such as temperature, current, and pressure.

ISLA224S20IR1Z is capable of providing a wide range of analog to digital conversion solutions, allowing customers to select the best solution for their specific application.

For applications that require high accuracy and low power, the ISLA224S20IR1Z is an ideal choice. Its small size and low power requirement make it a perfect choice for medical and industrial applications. Furthermore, its on-board temperature sensor provides precision temperature measurement and its high speed analog-to-digital conversion allows it to handle large amounts of data quickly and accurately.
