Product details
Overview
ADS8881EVM-PDK from Texas Instruments is a performance demonstration kit for the ADS8881 - an 18-bit, 1-MSPS true-differential unipolar SAR ADC - featuring USB-connected evaluation via MMB0 motherboard, onboard 4.5-V REF5045 reference, THS4521 differential driver, and support for bipolar (±4.3 V) or unipolar (0–8.6 V) analog inputs in single-ended or differential configurations.
For engineers reviewing the ADS8881EVM-PDK datasheet, ADS8881EVM-PDK pinout, ADS8881EVM-PDK application, or ADS8881EVM-PDK equivalent, this kit delivers turnkey evaluation of high-precision data acquisition systems requiring low-noise, low-power, and high-throughput ADC characterization with integrated signal conditioning, SPI interface control, and Windows-based ADCPro analysis software.
Technical Context
The ADS8881EVM-PDK integrates the ADS8881EVM daughter card with the DSP-based MMB0 motherboard to enable full-speed (1 MSPS) evaluation using TI's ADCPro software. It implements a complete analog front-end with THS4521 fully differential amplifier, REF5045 precision voltage reference, OPA333/THS4281 reference buffer chain, and TPS78833 LDO for regulated 3.3-V digital supply.
Digital interfacing uses 3-wire or 4-wire SPI (mode 0 or mode 1) at up to 80 MHz SCLK, with configurable CONVST and CS signals via jumpers JP2/J2 and JP3. The kit supports both differential and single-ended input modes, with common-mode shifting to 2.25 V for bipolar signal compatibility and onboard SMA and Samtec J1 interfaces for flexible signal injection.

FAQ
What is the ADS8881EVM-PDK used for?
The ADS8881EVM-PDK is a complete evaluation platform for the ADS8881 18-bit SAR ADC. It enables engineers to characterize dynamic performance (SNR, THD, SFDR), validate analog front-end design, and develop firmware using TI's ADCPro software. The kit includes hardware (MMB0 motherboard, ADS8881EVM, power supply, USB cable), reference schematics, and full documentation - all preconfigured for immediate 1-MSPS evaluation.
Does the ADS8881EVM-PDK include the ADS8881 ADC chip?
Yes, the ADS8881EVM-PDK includes the ADS8881IDGS device mounted on the ADS8881EVM daughter card in an MSOP-10 package. This is the exact production-grade 18-bit, 1-MSPS SAR ADC specified in TI's SBAS547 datasheet, not a sample or placeholder component.
What software is required to operate the ADS8881EVM-PDK?
ADCPro™ software is required - a free Windows-based GUI developed by Texas Instruments. Users must install ADCPro first, then load the dedicated ADS8881EVM-PDK plug-in (ads888x-adcproplugin-*.exe) downloaded from ti.com/tool/ads8881evm-pdk. No third-party drivers or SDKs are needed beyond standard Windows USB stack support.
Can the ADS8881EVM-PDK evaluate single-ended input signals?
Yes - the ADS8881EVM-PDK supports single-ended operation by grounding the A0(–) input (via SMA J4 or Samtec J1.10) while applying the signal to A0(+) (SMA J5 or J1.12). The THS4521 driver accommodates 0–8.6 V single-ended input range without saturation, preserving full 18-bit resolution when referenced to the 4.5-V onboard reference.
Is the ADS8881EVM-PDK RoHS compliant?
Yes - per Table 5 in the SBAU211 User's Guide, all bill-of-materials components in the ADS8881EVM-PDK are RoHS-compliant, including the ADS8881IDGS, REF5045IDGK, THS4521IDGK, and supporting passives. TI confirms compliance with EU Directive 2011/65/EU as stated in the evaluation board notice.
