LTC2392CUK-16#TRPBF

Overview

The LTC2392CUK-16#TRPBF 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 a typical SNR of 94dB at a 20kHz input frequency and achieves ±2LSB maximum integral nonlinearity with no missing codes at 16 bits. Power consumption is 110mW at the maximum sampling rate. The component includes an internal precision reference with a maximum temperature coefficient of ±20ppm/°C and offers both parallel and serial digital interface modes.

Feature Summary

• 16-bit resolution with guaranteed no missing codes and ±2LSB max INL
• 500ksps throughput rate with no pipeline delay or cycle latency
• Internal 4.096V reference with ±20ppm/°C max temperature coefficient
• Single 5V analog/digital supply with 1.8V to 5V I/O voltage support
• Parallel and serial interface options with internal conversion clock

Applications

• Medical imaging systems
• High-speed data acquisition
• Digital signal processing
• Industrial process control
• Automated test equipment (ATE)

Procurement Notes

Verify that the ordering suffix #TRPBF corresponds to the tape and reel packaging format required for automated assembly processes. Confirm the C grade designation indicates an operating temperature range of 0°C to 70°C. Ensure compatibility with the 48-lead QFN package dimensions during PCB layout planning.

Selection Notes

Select this model when a low noise SAR ADC with high dynamic range is required. The internal oscillator simplifies external timing requirements compared to devices requiring external clocks. Consider the 110mW power dissipation for thermal management in dense layouts. Verify that the ±4.096V differential input range matches the signal source specifications.

Part Context

This part belongs to the LTC2392-16 family of low noise, high-speed ADCs. It shares architectural similarities with the LTC2393-16 but operates at a lower throughput rate of 500ksps compared to the 1Msps variant. The component utilizes a 48-lead 7mm × 7mm plastic QFN package, distinct from the LQFP packages available in other variants of the same series.
