LTC2325HUKG-14#PBF

Analog To Digital Converters (ADC) Overview

The LTC2325HUKG-14#PBF is a quad, 14-bit + sign successive approximation register (SAR) analog-to-digital converter. It provides four simultaneous sampling channels at a throughput rate of 5Msps per channel with one-cycle latency. The device operates from a single 3.3V or 5V supply and features an 8VP-P differential input range with wide common mode rejection. Key electrical specifications include ±1LSB typical integral nonlinearity, 81dB SNR at fIN = 2.2MHz, and –88dB total harmonic distortion. It incorporates a low-drift internal reference and supports CMOS or LVDS serial interfaces.

Analog To Digital Converters (ADC) Feature Summary

• Internal low drift (20ppm/°C max) 2.048V or 4.096V temperature-compensated reference
• High-speed SPI-compatible serial interface supporting CMOS or LVDS

Analog To Digital Converters (ADC) Applications

• High speed data acquisition systems
• Communications
• Optical networking
• Multiphase motor control

Analog To Digital Converters (ADC) Procurement Notes

Verify the H suffix indicates the extended operating temperature range of –40°C to 125°C. Confirm the UKG package designation corresponds to the 52-lead (7mm × 8mm) plastic QFN form factor. Ensure the #PBF suffix denotes lead-free finish compliance for procurement matching.

Analog To Digital Converters (ADC) Selection Notes

Select this component when simultaneous multi-channel sampling is required at high speeds. The H grade is necessary for environments exceeding 85°C. Verify that the host interface logic levels match the OVDD supply range of 1.71V to 2.63V for either CMOS or LVDS operation modes.

Analog To Digital Converters (ADC) Part Context

This part belongs to the LTC2325 family of high-speed SAR ADCs. The HUKG variant specifically designates the industrial/high-temperature grade housed in the 52-lead QFN package. It shares architectural similarities with the LTC2325-16 and LTC2325-12 but offers specific 14-bit resolution optimized for dynamic performance.
