LTC2385CUH-18#TRPBF

Overview

The LTC2385CUH-18#TRPBF is an 18-bit, 5Msps successive approximation register (SAR) analog-to-digital converter manufactured by Analog Devices Inc. It operates from 5V and 2.5V supplies with a differential input range of ±4.096V. Key electrical specifications include a typical SNR of 95.7dB at 1MHz input frequency, 101dB SFDR, and ±1.5LSB maximum INL. The device features a serial LVDS interface, internal reference buffer, and dissipates 78mW at full throughput.

Feature Summary

• 18-bit resolution with guaranteed no missing codes
• 5Msps sampling rate with zero pipeline latency
• Serial LVDS digital interface supporting one-lane or two-lane modes
• Internal 2.048V reference with ±20ppm/°C temperature coefficient

Applications

• High speed data acquisition systems
• Imaging applications requiring wide dynamic range
• Communications equipment with significant signal bandwidth
• High speed control loop applications
• Instrumentation and ATE

Procurement Notes

Verify the #TRPBF suffix indicates tape and reel packaging rather than tube packaging. Confirm the 'C' grade designation corresponds to the 0°C to 70°C operating temperature range for this specific part number.

Selection Notes

Select this component when low noise and high linearity are required for 18-bit precision at 5Msps speeds. Ensure the system supports LVDS signaling for the digital interface and provides separate 5V and 2.5V power rails.

Part Context

This part belongs to the LTC2385-18 family of low-noise, high-speed SAR ADCs. It shares functional characteristics with other variants in the series but is distinguished by its commercial temperature grade and specific packaging configuration.
