Texas Instruments ADC12010EVAL/NOPB

Overview

ADC12010EVAL/NOPB from Texas Instruments is a 32-lead LQFP evaluation board for the ADC12010 12-bit, 10 MSPS analog-to-digital converter. It provides full access to all analog inputs (VIN+, VIN−), reference pins (VREF, VRP/VRM/VRN), digital I/O (CLK, OE, PD, D0–D11), and independent power domains (VA, VD, VDR, AGND/DGND/DR GND) to validate high-speed sampling performance, differential input linearity, and low-power operation in real-world signal chains.

For engineers reviewing the ADC12010EVAL/NOPB datasheet, ADC12010EVAL/NOPB pinout, ADC12010EVAL/NOPB application, or ADC12010EVAL/NOPB equivalent, this board enables direct measurement of ENOB (11.3 bits at 10.1 MHz), aperture jitter (2 ps rms), SNR (66 dB min), and power-down transition time (500 ns) under industrial temperature conditions (−40°C to +85°C) using TI's validated layout and grounding practices.

Technical Context

The ADC12010EVAL/NOPB implements the ADC12010's differential pipeline architecture with on-chip sample-and-hold, internal reference buffer, and separate analog/digital/output power domains. It supports 10 MSPS conversion with 6-clock-cycle latency and offset-binary output format, requiring precise 0.1 µF bypassing on all reference and supply pins per TI's layout guidelines.

It validates critical timing parameters including tOD (16.8 ns max), tAD (1.2 ns), and tAJ (2 ps rms), while enabling evaluation of PSRR1+ (69 dBFS) and PSRR2 (48 dBFS) against supply noise-key for instrumentation and waveform digitizer designs where clock-domain isolation and ground separation (AGND/DGND/DR GND) directly impact SFDR (69 dB min).

FAQ

What is the primary function of the ADC12010EVAL/NOPB?

The ADC12010EVAL/NOPB is an evaluation board for the ADC12010 12-bit, 10 MSPS analog-to-digital converter. It provides a fully laid-out, grounded, and bypassed platform to characterize dynamic performance-including ENOB (11.3 bits), SNR (66 dB min), and SFDR (69 dB min)-under real-world conditions. The board enables direct probing of all critical signals (VIN+, VIN−, CLK, D0–D11, PD, OE) and validates TI's recommended power domain separation and reference bypassing for the ADC12010.

Does ADC12010EVAL/NOPB support differential input testing?

Yes, ADC12010EVAL/NOPB fully supports differential input testing per the ADC12010's specification. It provides dedicated, impedance-matched connections to VIN+ and VIN− with independent common-mode voltage (VCM) control, enabling evaluation of angular error effects, full-scale swing compliance (≤VREF peak-to-peak), and optimal THD/SINAD performance. The board implements TI's layout guidance for minimizing ground loop currents between AGND and DGND to preserve 2 ps rms aperture jitter.

Can ADC12010EVAL/NOPB be used to verify power-down functionality?

Yes, ADC12010EVAL/NOPB includes direct access to the PD (Power Down) pin and supports verification of the ADC12010's power-down mode, which reduces total power consumption from 160 mW to 25 mW. The board allows measurement of tPD (500 ns exit time) and confirms proper isolation of VA, VD, and VDR domains during sleep state, ensuring no leakage paths compromise recovery stability or reference integrity.

What reference voltage range does ADC12010EVAL/NOPB accommodate?

ADC12010EVAL/NOPB accommodates the full specified VREF range of 1.0 V to 2.4 V for the ADC12010, with optimal performance at 2.0 V nominal. It provides dedicated pads and test points for VREF, VRP, VRM, and VRN, each designed for 0.1 µF monolithic capacitor bypassing to AGND-enabling validation of SNR degradation below 1.8 V and THD degradation above 2.2 V as documented in the ADC12010 datasheet.

Is ADC12010EVAL/NOPB compatible with other TI ADC evaluation platforms?

No, ADC12010EVAL/NOPB is purpose-built for the ADC12010 in 32-lead LQFP and is not mechanically or electrically compatible with other TI ADC evaluation boards. Its layout, grounding scheme (separate AGND/DGND/DR GND planes), and power routing are optimized specifically for the ADC12010's pipeline architecture, 6-clock latency, and 2.4V–5V output driver supply (VDR) requirements-not generalized across TI's ADC portfolio.
