Texas Instruments ADS9110EVM-PDK

Overview

ADS9110EVM-PDK from Texas Instruments is an evaluation module and performance demonstration kit for the ADS9110 - an 18-bit, 2-MSPS, fully-differential SAR analog-to-digital converter. It integrates the ADS9110 IC, OPA625/OPA376 input drivers, REF5050 voltage reference, TPS7A4700 LDO, and a Precision Host Interface (PHI) controller board with USB 2.0 connectivity for real-time data capture and analysis in high-precision test instrumentation.

For engineers reviewing the ADS9110EVM-PDK datasheet, ADS9110EVM-PDK setup, ADS9110EVM-PDK GUI software, or ADS9110EVM-PDK hardware interface, this page delivers verified technical context, USB-powered operation details, multiSPI® interface support, jumper-configurable common-mode options (0V/2.5V/floating), and integrated spectral/histogram/linearity analysis tools - all essential for ADC evaluation and system validation.

Technical Context

The ADS9110EVM-PDK comprises two PCBs: the ADS9110EVM (featuring the ADS9110 ADC, OPA625 differential drivers, REF5050 reference, and TPS7A4700 5.2V LDO) and the PHI controller (providing USB 2.0 host interface, 1.8V digital supply, I²C EEPROM for initialization, and SPI/multiSPI signal translation). All analog signal paths are optimized for 2-MSPS throughput with 1kΩ input impedance, 10nF differential filtering, and 160kHz anti-aliasing bandwidth.

Digital control uses Texas Instruments' multiSPI® protocol supporting single/dual/quad-SDO lanes, SDR/DDR data rates, and four clock source configurations - all configurable via the Windows-based GUI. Jumper-selectable common-mode (J1/J2) enables unipolar (2.5V), bipolar (0V), or AC-coupled floating inputs, with R1 resistor adjustment required for external source impedances beyond 0–32Ω in 0V mode.

FAQ

What is the ADS9110EVM-PDK used for?

The ADS9110EVM-PDK is a complete evaluation platform for the ADS9110 18-bit, 2-MSPS SAR ADC. It enables engineers to perform real-time performance characterization-including SNR, THD, SFDR, INL, and DNL-using its integrated OPA625 input drivers, REF5050 reference, TPS7A4700 LDO, and Windows GUI with spectral, histogram, and linearity analysis tools. ADS9110EVM-PDK eliminates the need for custom hardware development during early ADC selection and system prototyping.

Does the ADS9110EVM-PDK require an external power supply?

No. The ADS9110EVM-PDK is fully USB-powered via the included A-to-micro-B cable and the PHI controller board. The PHI derives 5.5V from USB, then generates clean 5.2V (for ADC and analog circuitry via TPS7A4700), 3.3V (for EEPROM), and 1.8V (for ADC digital interface) - all without external supplies. This simplifies lab setup and ensures consistent power integrity during evaluation.

Which software is required to operate the ADS9110EVM-PDK?

The ADS9110EVM-PDK requires the official Texas Instruments Windows GUI software, which includes LabVIEW™ Run-Time Engine, device drivers, and firmware for the PHI controller. The installer configures register-level control, multiSPI® interface selection, sampling rate tuning, and real-time visualization tools (time domain, FFT, histogram, linearity). ADS9110EVM-PDK software supports Windows 7 and Windows 8 (64-bit) and exports data to text files for post-processing.

How does the ADS9110EVM-PDK handle differential input signals?

The ADS9110EVM-PDK accepts only differential analog inputs via SMA connectors (J3/J7) or 100-mil headers (J4/J6), with strict 1kΩ input impedance and 10nF differential filtering. Input drivers use dual OPA625 op-amps configured for low-output impedance (2.2Ω up to 7MHz) to drive the dynamic switched-capacitor inputs of the ADS9110 at full 2-MSPS throughput. Single-ended signals are not supported - external sources must maintain balanced Vs(+) = –Vs(–) symmetry.

Can the ADS9110EVM-PDK evaluate unipolar and bipolar input ranges?

Yes. The ADS9110EVM-PDK supports unipolar (2.5V common-mode), bipolar (0V common-mode), and AC-coupled floating inputs using jumper configurations J1 and J2. For 0V common-mode, R1 is factory-set to 280kΩ to accommodate external source impedances from 0Ω to 32Ω. For 2.5V or floating modes, R1 must be adjusted per the user's source impedance to maintain ADC common-mode voltage between 2.5V and 2.6V - ensuring optimal linearity and avoiding OPA625 saturation. This configuration is documented in the ADS9110EVM-PDK User's Guide.
