LTC2422CMS#PBF

The LTC2422CMS#PBF is a high performance, easy-to-use analog-to-digital converter (ADC) for data acquisition applications. The device offers 24-bit no missing codes resolution, high speed conversion, and wide dynamic range. Additionally, the device provides extended resolution and low power consumption features. It is suitable for applications requiring precision conversion and reliable accuracy.

The LTC2422CMS#PBF is widely used in various applications such as industrial process control, test and measurement, and machine control. The device enables the conversion of two external inputs – a voltage source and an external reference –into a digital output. The analog input range can be adjusted to fit the application and can cover up to ±9.64 V. Additionally, the device features an internal 1.25V reference which can be utilized to enhance the conversion accuracy.

The device utilizes a Time Domain Delta-SigmaTM modulator with an integrated digital filter. The modulator allows for a capturing of the analog input into a digital form by utilizing a pulse width modulated (PWM) signal. The digital filter, on the other hand, converts the digital word into a 24-bit word at the output. This provides the desired resolution that makes the device suitable for precision data acquisition applications. Thanks to its high performance Time Domain Delta-SigmaTM modulator, the LTC2422CMS#PBF demonstrates a high sampling speed, with conversion times as low as 9.8 µs for a full scale differential input. Additionally, the device provides good accuracy, with a maximum total harmonic distortion of 0.003%.

The LTC2422CMS#PBF also features low power consumption and excellent power supply rejection rate. The device can operate with a supply voltage ranging from 2.7V to 3.6V and consumes only 400 µA of quiescent current. It even can be switched to a low-power mode that reduces the quiescent current to as low as 25 µA.

Overall, the LTC2422CMS#PBF is an excellent choice for applications that require a low power, high precision Data Acquisition - Analog to Digital Converters (ADC). The device is easy to integrate and provides high resolution, high accuracy, and extended dynamic range. All of these features in combination with its low power consumption makes the device very well suited for precision data acquisition applications in various industries.
