LTC2386CUH-18#PBF

Overview

The LTC2386CUH-18#PBF 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 incorporates an internal 2.048V reference with a buffer capable of generating a 4.096V output.

Procurement Notes

Verify the ordering suffix #PBF indicates lead-free finish and tube packaging for the commercial grade (C) variant. Confirm the temperature range is 0°C to 70°C. Ensure the package type is the 32-lead (5mm × 5mm) Plastic QFN. Cross-reference the manufacturer part number with official Analog Devices documentation to confirm current production status and availability channels.

Selection Notes

Select this component when 18-bit resolution and 10Msps sampling rate are required with low latency. The internal reference simplifies design if external precision references are not needed. The LVDS interface reduces pin count for high-speed data transfer. Consider the 97mW power consumption and thermal management requirements for the QFN package. Verify that the 5V analog supply and 2.5V digital supply constraints fit the system power architecture.

Part Context

This part belongs to the LTC238x-18 family of 18-bit SAR ADCs from Analog Devices. The 'C' suffix denotes the commercial temperature range (0°C to 70°C), while 'I' denotes industrial (-40°C to 85°C). The 'UH' indicates the 32-lead QFN package. Other family members include the LTC2385-18 (5Msps) and LTC2387-18 (15Msps), offering different throughput options within the same architectural framework.

Replacement Considerations

Publicly confirmed substitute part numbers are not provided in the source material. For equivalent performance, consider other parts within the LTC238x-18 family such as the LTC2385CUH-18#PBF (5Msps) or LTC2387IUH-18#PBF (15Msps), ensuring interface and timing requirements are met.
