Texas Instruments ADS8365M-EVM

Overview

ADS8365M-EVM from Texas Instruments is a full-featured evaluation module for the ADS8365 16-bit, 6-channel, simultaneous-sampling analog-to-digital converter. It supports single-ended and differential analog inputs, features a built-in +2.5-V reference, high-speed parallel data interface (16-bit), and modular connectivity to DSP platforms including C2000™, C5000™, and C6000™ series via 5-6K or HPA-MCU Interface Boards.

For engineers reviewing the ADS8365M-EVM datasheet, ADS8365M-EVM pinout, ADS8365M-EVM application, or ADS8365M-EVM equivalent, this page delivers verified hardware configuration details, jumper-controlled signal routing (HOLDx, CS, A0–A2, RESET), analog front-end flexibility (±2.5 V to ±10 V input range), and real-world interfacing guidance for industrial data acquisition and motor control prototyping.

Technical Context

The ADS8365M-EVM implements dual analog input paths: Channel A0 uses an OPA2132-based inverting buffer with programmable gain and biasing for ±2.5 V signals; Channel A1 employs an INA159 difference amplifier configured for direct ±10 V bipolar input with internal level translation. Remaining channels (B0/B1, C0/C1) route through passive R/C filters at J3 for user-defined front-end customization.

Digital control is configurable via jumpers W4, W6, and W10 to select between host-processor address-bus-driven mode (via J5) or discrete GPIO control of HOLD_A#/B#/C#, CS#, A0–A2, and RESET#. Parallel data output (D0–D15) is accessible via 32-pin Samtec header/socket J6, with even pins grounded and odd pins carrying data bits.

FAQ

What is the primary function of the ADS8365M-EVM?

The ADS8365M-EVM is a Texas Instruments evaluation module built to demonstrate and validate the ADS8365 16-bit, 6-channel simultaneous-sampling analog-to-digital converter. It provides complete analog front-end circuitry-including OPA2132 and INA159 amplifiers-parallel digital interface, configurable jumpers for HOLD/CS/A0–A2 control, and modular connectors (J3/J4/J5/J6) for integration with DSP platforms. The ADS8365M-EVM enables rapid prototyping of high-fidelity data acquisition systems without custom PCB design.

Can the ADS8365M-EVM support ±10-V analog inputs?

Yes, the ADS8365M-EVM supports ±10-V analog inputs on Channel A1 using the integrated INA159 difference amplifier, which provides built-in level translation and noninverting gain of 0.2 referenced to the ADS8365's internal +2.5-V reference. This configuration is factory-wired and documented in Figure 2 of SLAU189. Channel A0 can also be reconfigured for ±10-V operation by modifying resistor values (R1–R4) and adjusting W2 to position 2–3 per Table 1, but requires manual component changes.

How does the ADS8365M-EVM handle simultaneous sampling across all six channels?

The ADS8365M-EVM routes three independent active-low strobe signals-HOLD_A#, HOLD_B#, and HOLD_C#-to the ADS8365 device, each controlling one pair of analog input channels (A, B, C). When asserted simultaneously, these signals trigger synchronized sample-and-hold across all six inputs. These signals are accessible at J1 pins 5, 7, and 9 and can be driven directly by GPIO or via timer outputs (e.g., McBSP frame sync) when W10 is configured accordingly.

What digital interface options does the ADS8365M-EVM provide?

The ADS8365M-EVM offers a 16-bit parallel interface via J6 (32-pin Samtec header/socket), with D0–D15 mapped to odd-numbered pins and even pins grounded. Control signals-including RD#, CS#, A0–A2, RESET#, and BYTE-are routed to J1 and J5. Jumper W7 selects 8-bit (BYTE = high) or 16-bit (BYTE = low) output mode. J5 also provides access to interrupt (DC_INTa) and timer input (DC_TOUT) for host synchronization.

Is external power required, and what are the voltage specifications for the ADS8365M-EVM?

Yes, the ADS8365M-EVM requires external +5 VDC applied to JP1 pins 3 (+5VA) and 10 (+5VD), with tolerance of ±2.5% (4.75–5.25 V). The BVdd supply for input buffers accepts 2.7–5.5 V and is selectable via W5. All power inputs include filtering; optimal performance demands a clean, low-noise, well-regulated source. Test points TP1–TP3 and TP8–TP24 allow probing of key supply rails and signals without soldering.
