LTC2385IUH-16#TRPBF

Overview

The LTC2385IUH-16#TRPBF is a low noise, high speed, 16-bit successive approximation register (SAR) analog-to-digital converter. It operates at a throughput rate of 5Msps with no pipeline delay or cycle latency. The device features a serial LVDS digital interface supporting one-lane and two-lane output modes to optimize data rates. Key electrical specifications include a typical SNR of 93.8dB at 1MHz input frequency, an SFDR of 101dB, and a maximum INL of ±0.5LSB. Power consumption is 78mW at full sample rate, reducing to 10μW in power-down mode. It utilizes internal 2.048V reference and buffer outputs.

• ATE

Procurement Notes

Verify the #TRPBF suffix indicates tape and reel packaging containing 2500 units. Confirm the 'I' grade designation corresponds to the –40°C to 85°C operating temperature range. Ensure the QFN-32 package dimensions match the PCB footprint requirements for the 5mm × 5mm plastic body.

Selection Notes

Select this component when low latency is critical for control loops or imaging synchronization. The internal reference simplifies design by eliminating external precision references. Verify that the 5V analog supply and 2.5V digital supplies are available. Ensure the driving circuit can settle within the acquisition time to maintain linearity specifications.

Part Context

This part belongs to the LTC2385 family of high-speed SAR ADCs. The 'I' suffix denotes industrial temperature range operation. The 'UH' package code identifies the 32-lead QFN form factor. The '#TRPBF' suffix specifies lead-free tape and reel packaging for automated assembly processes.
