LTC2392CLX-16#PBF

Overview

The LTC2392CLX-16#PBF is a 16-bit, 500ksps 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 signal-to-noise ratio of 94dB at a 20kHz input frequency and guarantees no missing codes at 16 bits with a maximum integral nonlinearity of ±2LSB. It includes a precision internal reference with a maximum temperature coefficient of ±20ppm/°C and dissipates 110mW at full throughput. The component is housed in a 48-lead 7mm × 7mm plastic LQFP package.

Feature Summary

• 500ksps throughput rate with no pipeline delay or cycle latency
• 94dB typical SNR and ±2LSB maximum INL
• Internal reference with guaranteed 0.5% initial accuracy
• Parallel and serial interface modes with 1.8V to 5V I/O voltages

Applications

• Medical Imaging
• High Speed Data Acquisition
• Digital Signal Processing
• Industrial Process Control
• Instrumentation

Procurement Notes

Verify the specific temperature grade for the CLX suffix, which indicates an operating range of 0°C to 70°C. Confirm that the LQFP-48 package matches the design requirements. Ensure the internal reference specifications meet the system accuracy needs, as external references may be required for higher precision applications.

Selection Notes

Select this component when a high-speed 16-bit resolution is required with low power consumption. The internal oscillator simplifies timing considerations compared to external clock sources. Consider the ±4.096V differential input range for applications requiring maximum dynamic range without external level shifting.

Part Context

The LTC2392-16 is part of the LTC2393-16 family of low noise high speed ADCs. While the LTC2393-16 offers 1Msps throughput, the LTC2392-16 provides 500ksps performance. Both share similar architectural features, including the SAR structure and internal reference capabilities, but differ in sampling speed and associated power dissipation characteristics.
