Analog Devices Inc. DC2369A

Overview

DC2369A from Analog Devices is a demonstration board for the LT6656-2.5 precision series voltage reference IC, configured to validate ultralow-power (850nA), low-drift (10ppm/°C), and high-accuracy (±0.05%) performance in battery-powered instrumentation. It supports 2.5V output with ≤10mV dropout, 5mA output drive, and stability with ≥1µF output capacitance - enabling direct use as both ADC supply and reference in portable gas monitors and micropower remote sensing systems.

For engineers reviewing the DC2369A datasheet, DC2369A pinout, DC2369A application, or DC2369A equivalent, this page delivers verified board-level functionality, test-ready layout details, thermal and load regulation validation data, and direct integration guidance for precision analog signal chains requiring sub-1µA quiescent current and long-term stability.

Technical Context

The DC2369A implements the LT6656-2.5 in its 6-lead TSOT-23 package with VIN, VOUT, and dual GND pins (including internal GND*), supporting operation from 2.51V to 18V input while delivering stable 2.5V ±0.05% over –40°C to 85°C. Its design incorporates 0.1µF input bypassing and 1µF minimum output capacitance per LT6656 requirements, validated for <8ms settling time under 5mA load steps.

Board-level features include reverse input/output protection circuitry, compatibility with ceramic/tantalum/electrolytic capacitors (ESR ≤5Ω), and full support for the LT6656's class-B output stage - enabling both sourcing and sinking capability to manage transient recovery without external components.

FAQ

What is the primary function of the DC2369A evaluation board?

The DC2369A evaluation board is a ready-to-use hardware platform for characterizing the LT6656-2.5 precision voltage reference IC. It provides validated layout, decoupling, and interconnects to demonstrate 2.5V output accuracy (±0.05%), ultralow 850nA supply current, and 10ppm/°C temperature drift - directly supporting design-in decisions for battery-powered instrumentation where long-term stability and minimal quiescent power are critical. The DC2369A enables immediate bench testing without custom PCB development.

Does DC2369A support all LT6656 package variants?

No - the DC2369A is specifically configured for the LT6656-2.5 in the 6-lead TSOT-23 package (e.g., LT6656AIS6-2.5#TRPBF). It does not support DFN or LS8 variants due to mechanical and routing differences. Pin assignments, footprint, and thermal pad connections on DC2369A match only the TSOT-23 variant, and the board's test points and solder jumpers are optimized for that package's GND*, GND, VIN, VOUT, and NC pin configuration.

Can DC2369A be used to evaluate load regulation of the LT6656-2.5?

Yes - the DC2369A includes test points for VIN, VOUT, and GND, and supports external load switching via its VOUT header. With a 5mA-capable current source/sink and oscilloscope monitoring, users can directly measure the LT6656-2.5's load regulation performance (65ppm/mA typical) across 0–5mA loads, validating its suitability as both reference and supply for low-power ADCs. The board's 1µF output capacitor and 0.1µF input bypass meet LT6656 stability requirements for these measurements.

What thermal performance can be expected from DC2369A during extended operation?

The DC2369A operates within the LT6656-2.5's specified industrial temperature range (–40°C to +85°C) and leverages the TSOT-23 package's θJA of 230°C/W. At maximum 5mA load and 18V input, power dissipation remains below 80mW, resulting in <18°C junction rise above ambient - well within safe limits. No heatsinking is required, and the board's layout avoids thermal coupling between reference and sensitive analog traces to preserve measurement integrity.

Is DC2369A compatible with standard 0.1" prototyping headers and test equipment?

Yes - the DC2369A features 0.1"-spaced male pin headers for VIN, VOUT, and GND, fully compatible with standard oscilloscope probes, multimeters, and bench power supplies. Its compact 0.7" × 0.8" form factor fits standard breadboards and test fixtures. All critical signals are accessible without soldering, and the board includes silkscreen labels and polarity indicators to prevent misconnection during DC2369A evaluation.
