LTC2393IUK-16#TRPBF

Overview

The LTC2393IUK-16#TRPBF 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 supports a ±4.096V fully differential input range. The device achieves a typical signal-to-noise ratio (SNR) of 94.2dB at an input frequency of 20kHz. Key electrical parameters include a maximum integral nonlinearity (INL) of ±2LSB, no missing codes at 16 bits, and a power dissipation of 140mW at full throughput. It features an internal precision reference with a maximum temperature coefficient of ±20ppm/°C.

Feature Summary

16-bit resolution with guaranteed no missing codes and ±2LSB max INL
1Msps sampling rate with zero cycle latency in parallel and serial modes
Internal 4.096V reference with ±20ppm/°C max temperature coefficient
Single 5V supply operation with 1.8V to 5V I/O voltage compatibility

Applications

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

Procurement Notes

Verify the #TRPBF suffix confirms tape and reel packaging for automated assembly. Confirm the 'I' grade designation matches the required operating temperature range of –40°C to 85°C. Ensure the QFN-48 package footprint aligns with the PCB layout specifications provided in the datasheet.

Selection Notes

Select this component when high dynamic range and low noise are critical, indicated by the 94.2dB SNR specification. The internal oscillator simplifies timing requirements compared to external clock solutions. Consider the 140mW power dissipation for thermal management in dense layouts. Verify interface needs for either parallel or serial data output via the SER/PAR pin.

Part Context

This part belongs to the LTC2393-16 family of low-noise, high-speed SAR ADCs. The 'I' suffix denotes the industrial temperature grade (-40°C to 85°C), while the 'UK' indicates the 48-lead 7mm x 7mm plastic QFN package. The '#TRPBF' suffix specifies lead-free finish and tape and reel shipping configuration.
