Texas Instruments ADS8353Q1EVM

Overview

ADS8353Q1EVM from Texas Instruments is an evaluation module (EVM) and performance demonstration kit (PDK) for the ADS8353-Q1, a 16-bit, dual-channel, simultaneous-sampling SAR ADC with 600-kSPS throughput, SPI interface, and support for single-ended and pseudo-differential analog inputs. It includes the ADS8353-Q1EVM board, precision host interface (PHI) controller board, USB cable, and Windows-based GUI software for real-time data capture and analysis.

For engineers reviewing the ADS8353Q1EVM datasheet, ADS8353Q1EVM pinout, ADS8353Q1EVM application, or ADS8353Q1EVM equivalent, this page provides verified hardware configuration details, jumper-controlled input modes (single-ended/pseudo-differential), spectral/time-domain analysis capabilities, USB-powered operation, and integration with LabVIEW Run-Time Engine for automotive-grade ADC validation.

Technical Context

The ADS8353Q1EVM-PDK implements a complete signal chain: OPA320-Q1 unity-gain buffers drive both ADC channels via 49 Ω / 3.3 nF RC filters to achieve >83 dB SINAD and <–100 dB THD at 2 kHz full-scale input. The PHI controller handles USB 2.0 communication, SPI control of two ADS8353-Q1 devices, and I²C access to onboard EEPROM for initialization.

Power is delivered entirely over USB: the PHI supplies 3.3 V (EVM_DVDD) to digital logic, while the TPS7A47-Q1 LDO generates a low-noise 5.3 V (VA) rail for analog circuitry-including the ADC's AVDD and OPA320-Q1 drivers-enabling automotive-grade noise-sensitive evaluation without external supplies.

FAQ

What is the primary function of the ADS8353Q1EVM?

The ADS8353Q1EVM is an evaluation module and performance demonstration kit for the ADS8353-Q1 automotive SAR ADC. It enables engineers to validate dynamic performance (SINAD, THD, SFDR), configure input modes (single-ended or pseudo-differential), and perform real-time spectral and histogram analysis using included Windows GUI software-all powered and controlled via USB without external supplies.

Does the ADS8353Q1EVM require an external power supply?

No-the ADS8353Q1EVM operates entirely from USB power. The PHI controller board delivers 3.3 V to digital circuitry and powers the TPS7A47-Q1 LDO, which generates a clean 5.3 V analog supply (VA) for the ADS8353-Q1 and OPA320-Q1 drivers. No bench supply or external power source is needed for basic operation or performance testing.

How are analog input configurations set on the ADS8353Q1EVM?

Analog input mode (single-ended or pseudo-differential) is configured using physical jumpers: J6/J7 and JP6/JP7. For single-ended operation, pins 2–3 of J6/J7 are shorted; for pseudo-differential, pins 1–2 are shorted. JP6/JP7 route VREF or VREF/2 to the AINM inputs. These settings are documented in Table 3 of the SBAU327 user's guide and persist across GUI sessions.

Which software is required to operate the ADS8353Q1EVM?

The ADS8353Q1EVM requires the official TI EVM GUI software for Windows 7 (64-bit), which includes Time Domain, Spectral Analysis (with 7-term Blackman-Harris FFT), and Histogram tools. It also depends on the LabVIEW Run-Time Engine and a signed USB device driver installed during setup-both bundled with the installer and validated for compatibility with the ADS8353Q1EVM hardware.

Can the ADS8353Q1EVM evaluate both ADC channels simultaneously?

Yes-the ADS8353Q1EVM supports true simultaneous sampling of both ADC channels, as enabled by the underlying ADS8353-Q1 device architecture. The GUI's Channel Modes dropdown allows selection of "ADC A", "ADC B", or "Both" to capture synchronized data streams, essential for phase-sensitive applications like motor control or vibration analysis where channel-to-channel timing alignment is critical.
