Analog Devices Inc. DC2395A-H

Overview

DC2395A-H from Analog Devices is a high-performance evaluation board for the LTC2324-12 quad 12-bit + sign simultaneous-sampling SAR ADC. It supports 2 Msps per channel, 78.5 dB SNR at 500 kHz input, ±0.5 LSB INL (typ), and operation up to 125°C - enabling precision data acquisition in multiphase motor control and optical networking systems.

For engineers reviewing the DC2395A-H datasheet, DC2395A-H pinout, DC2395A-H application, or DC2395A-H equivalent, this page delivers verified board-level specifications, interface configuration options (CMOS/LVDS/DDR/SDR), power supply requirements (3.3 V/5 V VDD, 1.8–2.5 V OVDD), thermal design guidance for H-grade operation, and FPGA interfacing best practices using CLKOUT-skew-matched timing.

Technical Context

The DC2395A-H implements full hardware support for the LTC2324-12's four independent analog input channels (AIN1± through AIN4±), onboard 4.096 V reference buffers (REFOUT1–4), and dual-mode digital interface (CMOS/LVDS selectable via jumper). It routes all 52 pins of the QFN package-including differential SDOx+/– pairs, SCK±, CLKOUT±, and REFBUFEN-to accessible test points and FPGA-compatible headers.

Board-level design accommodates both internal reference operation (REFBUFEN = VDD) and external reference injection (REFBUFEN = GND), with dedicated 10 µF X5R ceramic decoupling per REFOUT pin and low-inductance ground plane tied to the exposed pad (Pin 53). Clock distribution uses matched trace lengths to maintain <500 ps aperture delay matching across channels.

FAQ

What is the primary function of the DC2395A-H evaluation board?

The DC2395A-H evaluation board is a fully assembled and tested platform for evaluating the LTC2324-12 quad 12-bit + sign simultaneous-sampling ADC. It provides direct access to all analog inputs, digital I/O, reference outputs, and power domains - enabling immediate characterization of dynamic performance (SNR, THD, SFDR), timing behavior, and interface compatibility with FPGAs or processors. The board ships with documented schematics, layout files, and software drivers to reduce time-to-validation for DC2395A-H users.

Does the DC2395A-H support both CMOS and LVDS digital interfaces for the LTC2324-12?

Yes, the DC2395A-H supports all digital interface modes of the LTC2324-12 via configurable jumpers and routing. CMOS mode (OVDD = 1.8 V or 2.5 V) uses single-ended SDO1–SDO4 and SCK/CLKOUT; LVDS mode enables differential signaling via SDOA±, SDOB±, SDOC±, SDOD±, SCK±, and CLKOUT± - with 100 Ω termination resistors pre-installed. Low-power LVDS is also supported by floating the CMOS/LVDS pin, as specified in the LTC2324-12 datasheet and implemented on DC2395A-H.

How is the internal reference configured on the DC2395A-H for the LTC2324-12?

On the DC2395A-H, the LTC2324-12's internal 4.096 V reference is enabled by default via a pull-up on REFBUFEN (Pin 43) to VDD. Each REFOUT1–4 pin is decoupled with a 10 µF X5R ceramic capacitor, and the common REF pin (Pin 8) includes a 1 µF low-ESR capacitor. To use an external reference, users disconnect the REFBUFEN jumper and drive REFOUT1–4 within 1.25 V to 5 V - a configuration validated on DC2395A-H with documented layout guidelines for noise isolation.

Can the DC2395A-H operate with the high-temperature grade LTC2324HUKG-12?

Yes, the DC2395A-H is rated for operation with the LTC2324HUKG-12 variant, which guarantees functionality from –40°C to +125°C. The board uses high-temperature-rated components (X5R ceramics, 125°C-rated connectors), features a thermally optimized 4-layer PCB with internal ground/power planes and exposed pad soldering, and includes thermal vias under the QFN footprint - all verified per Analog Devices' DC2395A-H design files and test reports for sustained 125°C junction operation.

What FPGA interfacing features does the DC2395A-H provide for the LTC2324-12?

The DC2395A-H provides robust FPGA interfacing for the LTC2324-12 via skew-matched CLKOUT output (with optional CLKOUTEN control), impedance-controlled differential traces for LVDS modes (100 Ω ±10%), and header-accessible SDO/SDO± signals routed to standard FPGA I/O banks. It includes SMA connectors for clock and data outputs, test points for all critical signals (CNV, SCK, REFOUTx), and documented timing margin analysis - ensuring reliable capture of 2 Msps/ch data streams in both SDR and DDR configurations when used with DC2395A-H.
