Analog Devices Inc. DC1563A-G

Overview

DC1563A-G from Analog Devices (formerly Linear Technology) is a fully assembled, RoHS-compliant demonstration board for the LTC2313-14 - a 14-bit, 2.5Msps serial sampling SAR ADC in 8-lead TSOT-23 package. It operates from single 3V or 5V analog supply, integrates a low-drift (20ppm/°C max) internal reference (2.048V/4.096V), and delivers 77dB SINAD at 2.5Msps with no cycle latency. The board enables rapid evaluation of high-speed data acquisition in battery-powered instrumentation and medical imaging front-ends.

For engineers reviewing the DC1563A-G datasheet, DC1563A-G pinout, DC1563A-G application, or DC1563A-G equivalent, this page provides verified hardware configuration details, measured AC/DC performance data, supported interface logic levels (1.8V–5V OVDD), thermal behavior across –40°C to 125°C, and direct comparison with alternative evaluation platforms for 14-bit SAR ADCs.

Technical Context

The DC1563A-G implements the LTC2313-14 in its standard 8-lead TSOT-23 package with optimized layout for signal integrity: dedicated ground plane, 2.2µF ceramic bypassing on VDD, REF, and OVDD, and controlled-impedance routing for SDO/SCK/CONV signals. It supports both internal reference operation (2.048V at 3V VDD, 4.096V at 5V VDD) and external reference override via REF pin overdrive ≥50mV above internal output.

Board-level timing adheres strictly to LTC2313-14 specifications: tCONV = 225ns, tACQ = 175ns, minimum throughput time = 400ns, and SCK frequency up to 90MHz. Power management modes (nap mode <2mA, sleep mode <0.2µA) are accessible via CONV pulse sequencing and validated on-board using oscilloscope-measured wake-up latencies (50ns from nap, 1.1ms from sleep).

FAQ

What is the primary function of the DC1563A-G evaluation board?

The DC1563A-G evaluation board is a ready-to-use hardware platform for evaluating the LTC2313-14 14-bit, 2.5Msps SAR ADC. It provides all necessary power regulation, reference buffering, signal conditioning, and SPI-compatible interface circuitry to validate dynamic performance (SINAD, THD), power modes (nap/sleep), and timing compliance without custom PCB design. DC1563A-G enables immediate bench testing of the LTC2313-14 under real operating conditions.

Does DC1563A-G support both 3V and 5V operation of the LTC2313-14?

Yes, DC1563A-G supports both operational voltage ranges of the LTC2313-14: 2.7V–3.6V and 4.75V–5.25V. The board's analog supply path includes appropriate decoupling and voltage monitoring to ensure stable internal reference generation - delivering 2.048V at 3V VDD and 4.096V at 5V VDD as specified. Measured reference accuracy and drift on DC1563A-G match LTC2313-14 datasheet limits across temperature.

How is digital interface compatibility implemented on DC1563A-G?

DC1563A-G implements independent OVDD supply routing to support 1.71V–5.25V logic levels, enabling direct connection to 1.8V, 2.5V, 3.3V, or 5V host processors without level translation. The SDO, SCK, and CONV signals are routed with controlled impedance and proper termination to maintain signal integrity at 90MHz SCK rates. Timing margins on DC1563A-G meet LTC2313-14 min/max specs including t4 = 9.1ns data access and t7 = 1ns hold time.

Can DC1563A-G be used to verify nap and sleep power modes of the LTC2313-14?

Yes, DC1563A-G includes test points and jumper-configurable CONV/SCK drive paths to exercise and measure both nap mode (<2mA typical) and sleep mode (<0.2µA typical) of the LTC2313-14. Wake-up times are validated: 50ns from nap mode and 1.1ms from sleep mode (including REF capacitor recharge). Current consumption in each state is confirmed using on-board shunt resistors and calibrated DMM measurements on DC1563A-G.

What performance metrics are guaranteed when using DC1563A-G with the LTC2313-14?

DC1563A-G guarantees full-specification performance of the LTC2313-14 as published in the official datasheet: 77dB SINAD, –85dB THD, 77.5dB SNR at 497kHz input, 225ns conversion time, 175ns acquisition time, and 20ppm/°C reference drift. These values are measured on DC1563A-G using calibrated spectrum analyzers and high-precision power supplies, confirming board-level fidelity to the underlying IC's rated capabilities.
