Texas Instruments ADS8860V2EVM-PDK

Overview

ADS8860V2EVM-PDK from Texas Instruments is a performance demonstration kit for the ADS8860 16-bit, pseudo-differential, unipolar SAR ADC - supporting up to 1 MSPS throughput, operating from 3.3-V AVDD/DVDD supplies, and featuring integrated precision reference (REF6050), drive amplifier (OPA320), and USB-connected Precision Host Adaptor (PHI) controller. It enables full dynamic characterization including SNR (93 dB), THD (–108 dB), and histogram analysis of DC linearity.

For engineers reviewing the ADS8860V2EVM-PDK datasheet, ADS8860V2EVM-PDK pinout, ADS8860V2EVM-PDK application, or ADS8860V2EVM-PDK equivalent, this kit delivers ready-to-run LabVIEW-based GUI software for time-domain capture, spectral analysis (7-term Blackman-Harris FFT), histogram evaluation, and SPI-configurable sampling control - all powered via USB with no external supply required.

Technical Context

The ADS8860V2EVM-PDK implements TI's Modular EVM architecture, where the ADS8860EVM daughter card interfaces exclusively through a 60-pin J2 connector to the PHI controller - a field-programmable gate array (FPGA)-based digital host that manages SPI communication (mode 0 or mode 1, up to 80 MHz SCLK), I²C read of onboard EEPROM for board identification, and USB 2.0+ host connectivity.

Analog signal conditioning includes an OPA320-driven input stage with R-C filtering optimized for 1-MSPS operation, and a REF6050 voltage reference with integrated high-bandwidth buffer driving the switched-capacitor VREF input - both validated to meet ADS8860 datasheet AC/DC specifications without external component changes.

FAQ

What is the ADS8860V2EVM-PDK used for?

The ADS8860V2EVM-PDK is a complete performance demonstration kit for evaluating the ADS8860 16-bit SAR ADC. It enables full characterization of dynamic parameters (SNR, THD, SFDR), DC linearity (INL/DNL via histogram), and timing behavior using its integrated PHI controller, LabVIEW GUI, and calibrated analog front-end - all powered and controlled over USB without external supplies or instruments.

Does the ADS8860V2EVM-PDK require an external power supply?

No. The ADS8860V2EVM-PDK is fully USB-powered: the PHI controller derives 5-V USB power and generates regulated 3.3-V DVDD, 3.3-V AVDD, and 5.3-V analog rails internally. LEDs on the ADS8860EVM board illuminate only after the GUI loads and the PHI enables these supplies - confirming proper power sequencing.

Which software is needed to operate the ADS8860V2EVM-PDK?

The ADS8860V2EVM-PDK requires the official Texas Instruments ADS8860EVM GUI software, built on LabVIEW Runtime Engine. It supports Windows 7/8/10 (64-bit), installs via executable wizard, and provides time-domain capture, spectral analysis (with 7-term Blackman-Harris window), histogram evaluation, and SPI configuration - all accessible through a single graphical interface.

Can the ADS8860V2EVM-PDK evaluate differential input signals?

No - the ADS8860V2EVM-PDK is configured for pseudo-differential, unipolar operation per the ADS8860 device specification. Its SMA input accepts single-ended 0–5 V signals with 2.5-V common-mode offset. While the ADS8860 IC supports pseudo-differential AINP/AINN inputs, the EVM board routes only AINP to the SMA jack; AINN is internally tied to a fixed reference and not externally accessible.

What components are included on the ADS8860EVM daughter card?

The ADS8860EVM daughter card includes the ADS8860IDGSR ADC (VSSOP-10), REF6050IDGKR reference (VSSOP-8), OPA320AIDBVR driver amplifier (SOT-23-5), TPS7A4700RGWR LDOs (VQFN-20), TPS3836K33DBVR supervisor (SOT-23-5), BR24G32FVT-3AGE2 EEPROM (TSSOP-8), and supporting passives - all laid out per TI's validated reference design for 1-MSPS operation.
