ADS8548SPMR

Analog To Digital Converters (ADC) Overview

The ADS8548SPMR is a high-performance analog-to-digital converter featuring eight simultaneous-sampling channels with 14-bit resolution. It utilizes a successive approximation register (SAR) architecture to achieve a maximum sampling rate of 600 kS/s per channel. The device supports bipolar single-ended inputs and offers flexible interface options, including parallel and serial connections. It operates on an analog supply voltage ranging from 4.5 V to 5.5 V and a digital supply between 2.7 V and 5.5 V. Key performance metrics include a signal-to-noise ratio of 85 dB and a power consumption of approximately 335 mW. The component is housed in a 64-pin LQFP package and functions within a temperature range of -40°C to +125°C.
