LINEAR 2PB_2393 LTC2393-16 16-Bit 1Msps SAR ADC Specification User Guide
Summary
This technical document provides comprehensive details on high-performance Analog-to-Digital Converters (ADCs) and associated drivers for precision data acquisition. It covers advanced features such as 16-bit resolution, exceptional Signal-to-Noise Ratio (SNR), one-shot operation, and wide temperature stability (-40°C to +125°C). Designed for engineers operating in demanding industrial or automotive environments, the manual explains optimal integration techniques—such as pairing devices with fast-settling drivers—to ensure uncompromised AC performance and reliable signal measurement.

LTC2393-16 IN–
Internal SPI or
AM PL IT UD (d BF S)
Reference Parallel
Wide Fully Differential Input Range Achieves 94.2d B SNR High SNR is achieved with a ±4.096V maximum signal swing that helps overcome background noise levels in demanding industrial environments. The LTC2393 features a temperature-compensated internal reference with 0.5% initial accuracy and 20ppm/°C (max) temperature coefficient over the automotive temperature range. The LTC2393-16 dissipates 140m W at 1Msps and features a shutdown mode that reduces power dissipation to 175µW when not converting. True no latency operation enables accurate one shot measurements even after idle periods with no minimum sample rate required. To achieve uncompromised AC performance, we recommend the fast settling LT6350 ADC Driver with rail-to-rail single-ended input and differential outputs.
