LTC2321HUFD-16#TRPBF

Analog To Digital Converters (ADC) Overview

The LTC2321HUFD-16#TRPBF is a dual-channel, 16-bit successive approximation register (SAR) analog-to-digital converter manufactured by Analog Devices Inc. It operates from a single 3.3V or 5V supply and features an 8V P-P differential input range with a wide common mode range. The device supports a sampling rate of 2Msps per channel with no cycle latency. Key electrical parameters include ±4LSB typical integral nonlinearity, 81dB signal-to-noise ratio at fIN = 500kHz, and -90dB total harmonic distortion. It integrates low-drift internal references of 2.048V or 4.096V and offers CMOS or LVDS serial interface options. The component is housed in a 28-lead 4mm × 5mm QFN package and is rated for operation up to 125°C.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific HU suffix indicates the extended industrial temperature range (-40°C to 125°C) as defined in the manufacturer's order information table. Confirm the #TRPBF suffix corresponds to the tape and reel packaging format required for automated assembly processes. Ensure compatibility with the host system's I/O voltage requirements before finalizing procurement specifications.

Analog To Digital Converters (ADC) Selection Notes

Select this component when dual-channel performance is required without sacrificing individual channel throughput rates. Consider the integrated reference buffers if board space constraints prevent the inclusion of external precision voltage sources. Evaluate the LVDS interface option if long-distance signal integrity is critical between the ADC and the processing logic.
