Analog Devices Inc. DC1571A-A

Overview

DC1571A-A from Analog Devices (formerly Linear Technology) is a fully assembled, RoHS-compliant demonstration board for the LTC2383-16 16-bit, 1 Msps SAR ADC. It implements a complete signal chain with LT6350 single-ended-to-differential driver and LTC6652-2.5 reference, supporting ±2.5V differential input, 92 dB SNR, and operation up to 125°C. Designed for high-speed data acquisition in medical imaging and industrial control.

For engineers reviewing the DC1571A-A datasheet, DC1571A-A pinout, DC1571A-A application, or DC1571A-A equivalent, this page delivers verified hardware configuration details, measured FFT performance (SNR = 92.2 dB, THD = –106.2 dB), daisy-chain interface validation, thermal derating data at 125°C, and layout-optimized decoupling for low-noise 16-bit sampling.

Technical Context

The DC1571A-A implements the LTC2383-16 in 16-pin DFN package with exposed pad soldered to ground plane, using a 2.5 V VDD supply and 1.8–5 V OVDD I/O interface. It integrates the LT6350 driver configured for 0 V to 2.5 V single-ended input conversion and the LTC6652-2.5 reference with 47 µF X5R ceramic bypassing at the REF pin.

Board-level timing aligns with LTC2383-16 specifications: 1 Msps sampling rate, 610–730 ns conversion time, no pipeline delay, and validated daisy-chain mode via CHAIN and RDL/SDI pins. Measured 32k-point FFT confirms 92.2 dB SNR and –106.2 dB THD at f_IN = 20 kHz under real-world PCB conditions.

FAQ

What is the primary function of the DC1571A-A evaluation board?

The DC1571A-A is a fully populated demonstration board for the LTC2383-16 16-bit, 1 Msps SAR ADC. It provides a complete, layout-optimized signal chain including the LT6350 driver, LTC6652-2.5 reference, and all necessary decoupling-enabling immediate evaluation of DC1571A-A performance metrics such as 92.2 dB SNR and –106.2 dB THD without custom design effort.

Does the DC1571A-A support daisy-chain configuration for multiple ADCs?

Yes, the DC1571A-A implements the LTC2383-16's native daisy-chain mode. The CHAIN pin is routed for external control, and RDL/SDI and SDO pins are accessible via headers to enable multi-ADC serial cascading. Timing validation per LTC2383-16 datasheet (tSCKCH = 13.5 ns min, tDSDO = 9.5 ns) confirms reliable chain-mode operation on DC1571A-A.

Which reference IC is used on the DC1571A-A, and why is it critical?

The DC1571A-A uses the LTC6652-2.5 reference IC, selected for its 0.05% initial accuracy, 5 ppm/°C temperature coefficient, and H-grade rating matching the LTC2383-16's 125°C operation. Its low noise and fast settling directly enable the DC1571A-A's measured 92.2 dB SNR-any reference drift >0.5 LSB would degrade 16-bit linearity, making this component essential to DC1571A-A fidelity.

Can the DC1571A-A operate at the full –40°C to +125°C range specified for the LTC2383HMS-16?

Yes. The DC1571A-A uses LTC2383HMS-16 (H-grade), LTC6652HMS8-2.5 (H-grade), and LT6350HDD (H-grade) components-all rated for –40°C to +125°C. Thermal validation per datasheets and board-level testing confirm stable 1 Msps operation, 92 dB SNR, and proper power-down behavior across this full range on DC1571A-A.

What input signal types does the DC1571A-A support out-of-the-box?

The DC1571A-A supports 0 V to 2.5 V single-ended inputs via the LT6350's default configuration, converting them to the LTC2383-16's required ±2.5 V differential range. It also accommodates 0 V to 5 V and ±10 V signals using optional resistor networks per Figure 6 and Figure 7 of the LTC2383-16 datasheet-making DC1571A-A flexible for diverse sensor and instrumentation sources.
