LTC2392HLX-16#PBF

Overview

The LTC2392HLX-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 supports a ±4.096V fully differential input range. The device features an internal precision reference with ±20ppm/°C temperature coefficient and guarantees 16-bit resolution without missing codes. Key performance metrics include a typical SNR of 94dB at fIN = 20kHz, ±2LSB maximum INL, and 110mW power dissipation at full throughput. It offers both parallel and serial interface modes with no pipeline delay or cycle latency.

Feature Summary

• 500ksps throughput rate with no cycle latency in parallel and serial modes
• Guaranteed 16-bit resolution with no missing codes and ±2LSB max INL
• Internal precision reference: 4.096V output, 0.5% initial accuracy, ±20ppm/°C max tempco
• Single 5V supply operation with 1.8V to 5V I/O voltage compatibility

Applications

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

Procurement Notes

Verify the specific temperature grade for the HLX suffix, which indicates –40°C to 125°C operation. Confirm the package type is the 48-lead 7mm × 7mm Plastic LQFP. Ensure the ordering suffix #PBF denotes lead-free finish and tray packaging as specified in the manufacturer's order information table.

Selection Notes

Select this component when high dynamic range is required with a single 5V supply. The ±4.096V differential input range maximizes signal swing. Choose between parallel or serial interfaces based on system pin count constraints; the serial mode allows daisy-chaining via SDIN/SDOUT. Ensure the host logic voltage matches the OVP range of 1.8V to 5V.

Part Context

This part belongs to the LTC2392-16 family, which includes variants with different temperature grades (C for commercial, I for industrial, H for extended) and packages (UK QFN, LX LQFP). The HLX suffix specifically identifies the extended temperature version in the LQFP package. Other family members like LTC2391-16 and LTC2393-16 offer different sampling rates (250ksps and 1MSPS respectively).

Replacement Considerations

Public confirmed substitutes within the same family include LTC2392CLX-16#PBF (0°C to 70°C) and LTC2392ILX-16#PBF (-40°C to 85°C) for lower temperature requirements. For higher speed, consider LTC2393-16; for lower speed, LTC2391-16. Cross-package replacements like LTC2392CUK-16#PBF are available if QFN footprint is acceptable.
