Data Acquisition - Analog to Digital Converters (ADC)

The ADS8354IPW is a high-performance, 14-bit analog to digital converter (ADC) designed to provide superior accuracy and performance over a wide range of application fields. It is designed to convert analog signals into digital signals with a low noise floor, high common-mode rejection, excellent linearity, and wide dynamic range. The device features a low power consumption, a high sampling rate, a wide input voltage range, and a low poise-dynamic offset.

Application Field

The ADS8354IPW is ideal for a variety of applications, such as industrial process control, data acquisition systems, medical instrumentation, automation and control, automotive, telecom and military/aerospace. It is also suitable for temperature and pressure sensing applications, motor control and power management, ultrasonic and machine vision systems, and process analytics.

Working Principle

The ADS8354IPW is designed to convert analog signals into digital signals with a high resolution (14-bit) in a wide range of applications. The device comprises a high-precision differential input stage, a low-noise high-impedance switch, a low-power low-noise amplifier, and a 14-bit successive-approximation register (SAR). The differential input stage enables high accuracy, low noise, and wide dynamic range measurement. The low-noise amplifier provides a low-noise output signal and minimizes noise sensitivity. The SAR implements an integrating sample-and-hold settling technique with improved stability and low power consumption. The device is capable of converting analog input signals from DC to 1MHz and providing output data rates from DC up to 220kHz.

The ADS8354IPW does not utilize any complex filters to reduce common-mode errors and to allow operation with a wide range of input voltages. This results in lower power consumption and improved dynamic performance. The differential input also helps to provide a high common-mode rejection ratio (CMRR) and a wide input voltage range (-Vref to +Vref). Additionally, the built-in transient protection circuit allows the device to withstand voltage surges up to ±25 V.

The ADS8354IPW is designed to operate over a wide range of temperature and the device can handle input voltages ranging from -Vref to +Vref. The device is also designed to be highly integrated with a simple three-wire interface and a power rail, making it ideal for a variety of applications where space, cost, and power efficiency matters.
