Texas Instruments ADS5232EVM

Overview

ADS5232EVM from Texas Instruments is an evaluation module designed to characterize the ADS5232 dual, 12-bit, 65-MSPS analog-to-digital converter under real-world signal, clock, reference, and supply conditions. It supports transformer-coupled and differential amplifier input paths, offers configurable internal/external reference, output enable per channel, and MSB format selection (offset binary or 2's complement). The EVM targets wireless infrastructure radio applications requiring high-fidelity digitization of IF signals.

For engineers reviewing the ADS5232EVM datasheet, ADS5232EVM pinout, ADS5232EVM application, or ADS5232EVM equivalent, this page provides verified physical layout details, power interface specifications, jumper configuration logic, TSW1100 interoperability guidance, and confirmed ADC device-level compatibility with ADS5231/ADS5237 variants.

Technical Context

The ADS5232EVM implements a 6-layer FR-4 PCB (5.15" × 5.05") with dedicated analog ground and dual power planes for noise isolation. It integrates two THS4503 differential amplifiers for single-ended-to-differential conversion on both channels and uses ADT4-1WT transformers for passive coupling paths.

Digital outputs are buffered via dual SN74AVC16244 level translators and routed to two 40-pin IDC headers (J8 and J21) compatible with TI's TSW1100 data capture board. Power is supplied through banana jacks supporting independent ±5 V (differential amplifier rails) and +3.3 V (ADC analog/driver supplies), with jumper-selectable internal reference (2.5 V) or external reference mode.

FAQ

What is the primary function of the ADS5232EVM?

The ADS5232EVM is an evaluation module built to assess the performance of the ADS5232 dual 12-bit 65-MSPS analog-to-digital converter. It provides configurable analog input paths (transformer-coupled or differential amplifier), selectable reference modes, channel-specific output enable, and buffered digital outputs compatible with TI's TSW1100. The ADS5232EVM enables engineers to validate timing, SNR, SFDR, and dynamic range under realistic RF receiver conditions before final system integration.

Which ADC devices does the ADS5232EVM support?

The ADS5232EVM is explicitly designed for the ADS5232 but also supports ADS5231 (40-MSPS) and ADS5237 (10-bit, 65-MSPS) as stated in its official user guide (SBAU111B). All three devices share identical pinout, power architecture, and interface logic on the EVM, allowing hardware reuse across speed and resolution variants without PCB modification. The ADS5232EVM documentation confirms functional equivalence for jumper settings, power sequencing, and TSW1100 software recognition.

How is the ADS5232EVM powered?

The ADS5232EVM accepts power via four banana jack sockets: +3.3 V analog supply (J11/J10), +3.3 V driver supply (J17/J18), and ±5 V differential amplifier supplies (J14/J13/J12). A single 3.3-V supply suffices only when using transformer-coupled inputs and internal reference mode; ±5 V is mandatory for differential amplifier operation. Current limits must be set to ≤500 mA per rail, and voltage must remain within –0.3 V to 3.8 V on AVDD/DVDD to prevent damage to the ADS5232EVM.

Can the ADS5232EVM connect directly to the TSW1100?

Yes - the ADS5232EVM connects directly to the TSW1100 using its two 40-pin IDC headers: J8 mates with TSW1100 J2, and J21 mates with TSW1100 J1. Digital outputs from the ADS5232 are buffered by SN74AVC16244 drivers on the ADS5232EVM, ensuring signal integrity and voltage-level compatibility. TI's TSW1100 software automatically detects the ADS5232EVM when selected in the chip selector, enabling immediate data acquisition without firmware updates or hardware adaptation.

What are the key configuration jumpers on the ADS5232EVM?

The ADS5232EVM uses five 3-pin jumpers: W1 selects internal (pins 1–2) or external (pins 2–3) reference; W2/W4 enable Channel B/Channel A output respectively; W3 places the ADS5232 into power-down mode (pins 1–2); W9 sets MSB format (pins 2–3 = offset binary, pins 1–2 = 2's complement). These jumpers allow full functional reconfiguration of the ADS5232EVM without soldering or component replacement, supporting rapid iteration across test scenarios.
