LTC2393CLX-16#PBF

Overview

The LTC2393CLX-16#PBF is a 16-bit, 1Msps successive approximation register (SAR) analog-to-digital converter manufactured by Analog Devices Inc. It operates from a single 5V supply and features a ±4.096V fully differential input range. The device achieves a typical SNR of 94.2dB at 20kHz input frequency and guarantees 16-bit no missing codes with a maximum INL of ±2LSB. It includes an internal precision reference with a ±20ppm/°C temperature coefficient. Power dissipation is 140mW at full throughput, with nap and sleep modes for power reduction. The component is housed in a 48-lead LQFP package.

Procurement Notes

Verify the specific ordering suffix to confirm the package type and temperature grade. The CLX suffix indicates a 48-lead LQFP package with a commercial operating temperature range of 0°C to 70°C. Ensure compatibility with the required thermal management solutions for the target application environment.

Selection Notes

Select this part when a high-speed, low-noise 16-bit ADC is required with a wide differential input range. The internal reference simplifies design but external references may be used for higher accuracy. Consider the LQFP package constraints and verify that the 1.8V to 5V I/O voltage range matches the system logic levels.

Part Context

This component belongs to the LTC2393-16 family, which also includes variants with different sampling rates such as the LTC2392-16 (0.5Msps) and LTC2391-16 (0.25Msps). These devices share similar architectural features and pinouts, allowing for potential design flexibility across different speed requirements within the same product line.

Replacement Considerations

Direct replacements within the same family include the LTC2393ILX-16#PBF for extended industrial temperature ranges (-40°C to 85°C) and the LTC2393HLX-16#PBF for automotive/high-temperature applications (-40°C to 125°C). Both maintain identical electrical specifications and pinouts.
