Product details
Overview
ADS8382EVM from Texas Instruments is a fully featured evaluation board for the ADS8382 18-bit, 600 kSPS serial-interface analog-to-digital converter. It integrates on-board signal conditioning using the THS4131 fully differential amplifier, a REF1004C-2.5 voltage reference with OPA627 buffer, and digital I/O buffers (SN74AHC1G125) for FPGA/processor interfacing in high-fidelity data acquisition systems.
For engineers reviewing the ADS8382EVM datasheet, ADS8382EVM pinout, ADS8382EVM application, or ADS8382EVM equivalent, this page delivers verified technical context, power supply configuration options (+15 V/–15 V analog, +5 V/+3.3 V digital), jumper-controlled reference selection (internal/REF1004C-2.5/user-supplied), and dual-row Samtec connectors (P1/P2) for rapid prototyping with DSP starter kits.
Technical Context
The ADS8382EVM implements a pseudo-bipolar differential input interface optimized for 100 kHz signals, with common-mode voltage set to 2.0 V via potentiometer RP1 and adjustable using the REF1004C-2.5 reference buffered by OPA627AU. The THS4131 amplifier is factory configured in unity-gain single-ended-to-differential mode with C0G capacitors (68 pF, 6800 pF) for low distortion.
Digital control uses a 20-pin dual-row header (P2) exposing CS, SCLK, FS, CONVST, BUSY, SDO, and PD signals compatible with TI's 5-6K interface card for C5000/C6000 DSKs. Power delivery supports ±15 V op-amp rails, +5 V analog supply (AVCC), and selectable +5 V or +3.3 V digital supply (BVDD) via jumper W1.

FAQ
What is the primary function of the ADS8382EVM?
The ADS8382EVM is an evaluation board for the ADS8382 18-bit, 600 kSPS serial-output SAR ADC. It provides complete signal chain implementation-including THS4131-based differential input buffering, REF1004C-2.5 reference with OPA627 amplification, and SN74AHC1G125 digital buffers-enabling immediate performance characterization and system integration testing of the ADS8382 in real-world applications.
Which ADC does the ADS8382EVM evaluate?
The ADS8382EVM evaluates the ADS8382IBRHPT: a 18-bit, 600 kSPS, serial-interface SAR analog-to-digital converter in a 28-pin PQFP package. All analog and digital circuitry on the ADS8382EVM-including input buffer, reference path, and interface logic-is specifically designed and optimized for the electrical and timing requirements of the ADS8382 device.
How is the analog input configured on the ADS8382EVM?
The ADS8382EVM ships with the THS4131 configured in unity-gain single-ended-to-differential mode, with VOCM set to 2.0 V via RP1. Single-ended input applies to P1 pin 2 or SMA J2 (+IN); differential input uses P1 pins 1/2 or SMA J1/J2. Resistors R4/R31 can be installed and R16 removed to reconfigure for fully differential input per the ADS8382EVM User's Guide.
What reference voltage options does the ADS8382EVM support?
The ADS8382EVM supports three reference configurations: internal 4.096 V reference (enabled via SJP4), on-board REF1004C-2.5 (2.5 V, buffered to 4.1 V by OPA627AU), or user-supplied external reference applied to P1 pin 20. Jumper settings SJP1–SJP5 determine routing and buffering, with factory defaults favoring the REF1004C-2.5 solution.
Can the ADS8382EVM interface directly with TI DSP starter kits?
Yes-the ADS8382EVM connects directly to TI C5000 and C6000 Digital Signal Processor starter kits (DSK) via the 5-6K interface card. Its P2 connector exposes all required serial control signals (CS, SCLK, FS, CONVST, BUSY, SDO, PD) in standard pinout alignment, enabling plug-and-play software-driven evaluation without custom adapter hardware.
