Analog Devices Inc. LTC2386IUH-16#PBF

Overview

LTC2386IUH-16#PBF from Analog Devices (formerly Linear Technology) is a 16-bit, 10Msps successive approximation register (SAR) analog-to-digital converter with serial LVDS interface, ±0.5LSB INL (max), 93.8dB SNR (typ @ 1MHz), and 8.192V_P-P differential input range. It operates from 5V and dual 2.5V supplies, features an internal 2.048V reference with ±20ppm/°C tempco, and targets high-speed imaging, instrumentation, and control-loop applications requiring no pipeline latency.

For engineers reviewing the LTC2386IUH-16#PBF datasheet, LTC2386IUH-16#PBF pinout, LTC2386IUH-16#PBF application, or LTC2386IUH-16#PBF equivalent, key selection considerations include guaranteed 16-bit no-missing-codes operation, LVDS one/two-lane output mode flexibility, Nyquist sampling up to 5MHz, 97mW power dissipation at full rate, and –40°C to +85°C industrial temperature grade.

Technical Context

The LTC2386IUH-16#PBF implements a true SAR architecture with no pipeline delay, enabling deterministic timing for closed-loop control. Its fully differential input stage accepts ±4.096V signals referenced to VCM = 2.048V, with 200MHz –3dB input bandwidth and 75dB CMRR at 1MHz.

Conversion is initiated by a differential LVDS CNV+ / CNV– signal or single-ended CNV+ (CNV– tied to GND), with tCONV = 72ns (typ) from CNV edge to valid data. The serial LVDS interface supports programmable one-lane (16-bit serial) or two-lane (8-bit parallel per lane) output modes, synchronized to DCO-echoed version of CLK-minimizing skew (±200ps).

FAQ

What is the operating temperature range for the LTC2386IUH-16#PBF?

The LTC2386IUH-16#PBF is rated for industrial operation from –40°C to +85°C. All key specifications-including INL (±0.5LSB max), SNR (93.8dB typ), and timing parameters-are guaranteed across this full range. This distinguishes it from the commercial-grade LTC2386CUH-16#PBF (0°C to 70°C) and confirms its suitability for harsh-environment applications like factory automation and outdoor instrumentation.

Does the LTC2386IUH-16#PBF require an external reference?

No, the LTC2386IUH-16#PBF includes a fully integrated 2.048V internal reference with ±20ppm/°C max temperature coefficient and a 2× gain reference buffer delivering 4.096V. An external reference is optional-only needed when higher initial accuracy or lower drift than the internal reference provides is required. If using the internal reference, REFIN should be bypassed to GND with ≥0.1μF ceramic capacitance.

How does the LVDS interface of the LTC2386IUH-16#PBF operate in one-lane versus two-lane mode?

In one-lane mode (TWOLANES = low), the LTC2386IUH-16#PBF outputs all 16 bits sequentially on DA+/DA– at 160MHz (10Msps × 16 bits). In two-lane mode (TWOLANES = high), it outputs even bits on DA+/DA– and odd bits on DB+/DB– simultaneously at 80MHz (10Msps × 8 bits per lane), halving the data rate per lane and easing receiver timing closure-especially beneficial in dense PCB layouts or with slower FPGA I/O banks.

Can the LTC2386IUH-16#PBF be used with single-ended input signals?

The LTC2386IUH-16#PBF is designed exclusively for fully differential analog inputs (IN+, IN–) with strict common-mode requirements (2.048V ±0.1V). Single-ended signals must be converted to differential format using a high-performance transformer or fully differential amplifier (FDA) such as the LTC6409 or ADA4941-1. Direct single-ended connection violates the input specification and degrades CMRR, INL, and THD performance.

What is the power consumption of the LTC2386IUH-16#PBF in power-down mode?

In power-down mode (PD pin low), the LTC2386IUH-16#PBF reduces total supply current to ≤10μW-comprising ≤1μA from VDD, ≤2μA from VDDL, and ≤2μA from OVDD. This ultra-low quiescent state preserves system energy budget during idle periods while allowing full functionality restoration within nanoseconds upon PD assertion, making it ideal for battery-powered or duty-cycled high-speed acquisition systems.
