Texas Instruments ADS8910BEVM-PDK

Overview

ADS8910BEVM-PDK from Texas Instruments is a precision evaluation module designed to characterize the ADS8910B 18-bit, 1-MSPS SAR ADC in high-fidelity data acquisition systems. It integrates the OPA625 ultra-low-distortion driver, supports dual-supply (±5 V) and single-supply (5 V/3.3 V) operation, delivers 91.88 dB SNR and 14.97 ENOB, and enables full-speed FFT analysis with <−110.8 dBc THD.

For engineers reviewing the ADS8910BEVM-PDK datasheet, ADS8910BEVM-PDK pinout, ADS8910BEVM-PDK application, or ADS8910BEVM-PDK equivalent, this module provides validated signal chain performance for precision SAR ADC evaluation-including THD+N-limited driver interface, reference buffer stability, and layout-optimized analog routing for sub-16-bit ENOB integrity at 1 MSPS.

Technical Context

The ADS8910BEVM-PDK implements a complete signal chain for the ADS8910B: it uses the OPA625 in high-drive mode (120 MHz GBW, 115 V/µs slew rate) to drive the ADC's switched-capacitor input with 280 ns 16-bit settling, while maintaining −122 dBc HD2 and −140 dBc HD3 at 100 kHz. The board incorporates a low-noise 4.096-V reference (REF5040) and supports both pseudo-differential and fully differential input configurations.

It features configurable power delivery (LDO-based for low noise, or DC/DC for efficiency), on-board clock conditioning via CDCE72010 jitter cleaner, and FPGA-controlled digital interface (SPI) for register access and timing control-enabling deterministic sampling, dithering, and gain/offset calibration validation per JEDEC JESD204B-aligned test methodology.

FAQ

What is the primary function of the ADS8910BEVM-PDK?

The ADS8910BEVM-PDK is a Texas Instruments evaluation module built around the ADS8910B 18-bit, 1-MSPS SAR ADC. Its purpose is to provide a fully characterized, layout-optimized platform for validating dynamic performance-including SNR, THD, SINAD, and ENOB-in real-world signal chain configurations. The ADS8910BEVM-PDK includes the OPA625 driver, REF5040 reference, clock conditioning, and SPI/FPGA interface to replicate production-level behavior of the ADS8910B under controlled test conditions.

Does the ADS8910BEVM-PDK support single-ended or differential input modes?

Yes, the ADS8910BEVM-PDK supports both pseudo-differential and fully differential input configurations via jumper-selectable termination and routing. It accommodates AC-coupled and DC-coupled inputs, with onboard OPA625 configured for either gain-of-1 unity-gain buffering or gain-of-2 single-ended-to-differential conversion. Input common-mode range is actively maintained at VREF/2 (2.048 V) using precision resistive dividers and active feedback, ensuring optimal ADS8910B performance across all supported modes.

What clocking options does the ADS8910BEVM-PDK provide for the ADS8910B?

The ADS8910BEVM-PDK integrates the CDCE72010 programmable clock generator to deliver low-jitter sampling clocks to the ADS8910B. It supports external 10–50 MHz crystal or LVCMOS clock input, and can generate precise 1-MSPS sampling clocks with <1 ps RMS jitter (integrated 10 kHz–20 MHz). The ADS8910BEVM-PDK also provides direct SMA clock input for lab-grade signal generators, enabling jitter sensitivity analysis and phase-noise correlation studies with the ADS8910B.

Can the ADS8910BEVM-PDK be used with other ADCs besides the ADS8910B?

No-the ADS8910BEVM-PDK is specifically designed and optimized for the ADS8910B and is not mechanically or electrically compatible with other ADCs. Its PCB layout, power delivery network, reference decoupling, driver biasing, and digital interface are all tailored to the ADS8910B's pinout, timing requirements, and dynamic loading characteristics. Substituting another ADC would require redesign of analog routing, power sequencing, and SPI register mapping-making the ADS8910BEVM-PDK a dedicated evaluation tool for the ADS8910B only.

What software and firmware tools are included with the ADS8910BEVM-PDK?

The ADS8910BEVM-PDK ships with TI's Precision Labs ADC software suite, including GUI-based data capture (TIDA-01570 firmware), real-time FFT analysis, histogram plotting, and INL/DNL calculation tools. Firmware is FPGA-hosted (Xilinx Artix-7) and supports register-level control of ADS8910B configuration bits-including internal reference enable, offset calibration trigger, and digital gain adjustment. All source code, HDL, and Python API drivers are provided under TI's open-source license for customization and integration into automated test systems.
