Texas Instruments ADS8364M-EVM

Overview

ADS8364M-EVM from Texas Instruments is a full-featured evaluation module for the ADS8364 and ADS8365 16-bit, 250-kHz, 6-channel simultaneous-sampling analog-to-digital converters. It provides configurable single-ended or differential analog inputs, built-in +2.5-V reference, high-speed parallel digital interface, and modular connectivity to DSP platforms including C5000™, C6000™, and C2000™ series via 5-6K or HPA-MCU Interface Boards.

For engineers reviewing the ADS8364M-EVM datasheet, ADS8364M-EVM pinout, ADS8364M-EVM application, or ADS8364M-EVM equivalent, this page delivers verified hardware configuration details, jumper-controlled signal routing (HOLDA/B/C, CS, A0–A2, RESET#), analog front-end options (±2.5 V to ±10 V), parallel data bus access (D0–D15), and EVM-specific power sequencing requirements.

Technical Context

The ADS8364M-EVM implements a dual-path analog interface: Channel A0 uses OPA2132 op-amps with inverting gain=1 and +2.5-V bias for ±2.5-V single-ended input; Channel A1 employs INA159 difference amplifier (gain=0.2) for direct ±10-V bipolar input. Remaining channels (B0/B1, C0/C1) route through R/C filters at J3 for user-defined conditioning.

Digital control is fully configurable via jumpers: W4/W6 select address/control pin sourcing (J5 vs. shunt headers); W7 sets BYTE mode (16-bit default); W8 selects clock source (J5 or BNC J7); W10 enables GPIO or timer-driven HOLD strobes. Parallel data output (D0–D15) and control signals (RD#, EOC#, FD) are accessible via 32-pin Samtec header J6.

FAQ

What is the primary function of the ADS8364M-EVM?

The ADS8364M-EVM is an evaluation module for the ADS8364 and ADS8365 16-bit, 6-channel simultaneous-sampling ADCs. It provides a complete, tested hardware platform-including analog front-end circuitry (OPA2132, INA159), parallel digital interface, configurable jumpers, and modular interconnects-to validate performance, prototype signal chains, and integrate with TI DSP platforms. The ADS8364M-EVM itself is not an IC but a PCB-based development tool enabling rapid characterization of the underlying ADC devices.

Does the ADS8364M-EVM include an onboard voltage reference?

Yes, the ADS8364M-EVM uses the internal +2.5-V reference of the ADS8364 or ADS8365 by default, enabled via jumper W3 (pins 2–3). An external reference can be applied at test point TP10 (referenced to TP12), while the internal reference remains connected to the U1 op-amp bias network to maintain proper mid-point level shifting for channel A1. This dual-reference flexibility supports both quick evaluation and precision calibration workflows using the ADS8364M-EVM.

How are the HOLD signals (HOLDA, HOLDB, HOLDC) controlled on the ADS8364M-EVM?

HOLD signals are driven as active-low strobes and accessible via J1 pins 9 (HOLD_A#), 7 (HOLD_B#), and 5 (HOLD_C#). Jumper W10 (3×3 header) configures each HOLDx line for either GPIO control (default) or timer-driven operation using host processor outputs. The ADS8364M-EVM schematic confirms direct connection from J1 to the ADS8364 device pins 56–58, enabling true simultaneous sampling across all six channels when all three HOLD signals are asserted together - a core capability validated on the ADS8364M-EVM.

Can the ADS8364M-EVM interface directly with microcontrollers or FPGAs?

Yes - the ADS8364M-EVM supports direct interfacing with microcontrollers and FPGAs via its 16-bit parallel data bus (J6, D0–D15), control lines (RD#, CS#, RESET#, EOC#), and address/control pins (A0–A2, BYTE) exposed on J1 and J5. Jumpers W4, W6, and W7 allow full customization of signal sourcing and bus width. No level-shifting is required for 5-V tolerant logic; for 3.3-V systems, external buffers may be needed. This direct-connect capability is explicitly documented for use with C2000™ MCUs and custom logic designs using the ADS8364M-EVM.

What are the power supply requirements for the ADS8364M-EVM?

The ADS8364M-EVM requires +5 VDC (±5%, 4.75–5.25 V) for AVdd and DVdd, supplied via JP1 pins 3 (+5VA) and 10 (+5VD). BVdd (input buffer supply) is selectable between 2.7 V and 5.5 V using jumper W5. Clean, well-regulated supplies are mandatory: analog sections use dedicated ±12-V for OPA2132 (via TP1/TP2), and ferrite beads (FB1–FB5) isolate digital noise. Power sequencing is not required, but optimal SNR performance on the ADS8364M-EVM depends on low-noise, low-ripple sources as specified in SLAU189.
