LTC2386CUH-18#TRPBF

Overview

The LTC2386CUH-18#TRPBF is an 18-bit, 10Msps successive approximation register (SAR) analog-to-digital converter manufactured by Analog Devices Inc. It operates from 5V and 2.5V supplies with a typical power dissipation of 97mW at full speed. The device features a serial LVDS digital interface supporting one-lane or two-lane output modes to optimize data rates. Key electrical specifications include a guaranteed 18-bit no missing codes performance, ±1.75LSB maximum integral nonlinearity (INL), and a typical signal-to-noise ratio (SNR) of 95.7dB at a 1MHz input frequency. It utilizes an internal 2.048V reference with a maximum temperature coefficient of 20ppm/°C.

• Internal 2.048V Reference with ±20ppm/°C Max Temperature Coefficient

Applications

• High Speed Data Acquisition
• Imaging Systems
• Communications
• Control Loops
• Instrumentation
• Automated Test Equipment (ATE)

Procurement Notes

Verify the ordering suffix #TRPBF indicates tape and reel packaging for automated assembly. Confirm the 'C' grade designation corresponds to the commercial operating temperature range of 0°C to 70°C. Ensure the specific lot marking matches the datasheet identifier '238618'. Cross-reference the manufacturer part number with official Analog Devices documentation to validate authenticity and revision status before procurement.

Selection Notes

Select this component when an 18-bit resolution and 10Msps sampling rate are required with low latency. The internal reference and buffer simplify design if external precision references are not mandatory. Consider the LVDS interface requirements for high-speed digital routing. Evaluate the 97mW power consumption against thermal constraints in the 32-lead QFN package. Verify that the 5V analog supply and 2.5V digital/output supplies align with system power architecture.

Part Context

This part belongs to the LTC2386-18 family of high-speed SAR ADCs. The 'CUH' designation specifies the commercial temperature grade and the 32-lead 5mm x 5mm QFN plastic package. The '#TRPBF' suffix denotes the lead-free tape and reel shipping configuration. Other variants in the series include the I-grade version for industrial temperatures and PBF tube packaging options.

Replacement Considerations

Publicly confirmed substitute part numbers are not provided in the source material. For pin-compatible alternatives within the same family, consider the LTC2385-18 (5Msps) or LTC2387-18 (15Msps). Verify that any replacement maintains the 18-bit resolution, LVDS interface compatibility, and supply voltage requirements.
