UI: [ V003585 ]
**[ New – Open box ]**
INCLUDES: [MODULE]
FEATURED DESCRIPTION:
The Texas Instruments ADS131M08EVM is the official evaluation module for the ADS131M08, an 8‑channel, 24‑bit, simultaneous‑sampling delta‑sigma ADC. The EVM exposes the full performance of the ADC and provides USB‑to‑SPI interfacing for rapid evaluation.
⭐ Core Specs (from ADS131M08 device, used on the EVM)
Resolution: 24‑bit
Channels: 8 fully simultaneous‑sampling ADC channels
Max sample rate: 32 kSPS per channel
Architecture: Delta‑Sigma (ΔΣ) ADC with integrated digital filters
Input type: Differential or single‑ended per channel
Programmable Gain Amplifier (PGA): Gains from 1 to 128
Input impedance: ≥ 1 MΩ at high PGA gains (8–128)
SNR: ~101 dB typical
Power consumption: ~6 mW typical for the ADC IC; EVM total ~21.5 mW at 32 kSPS (per Digi‑Key listing)
Startup time: First data within 0.5 ms after supply ramp
Communication interface: SPI (4‑wire)
Supply voltages:
Analog: 2.7–3.6 V
Digital: 1.65–3.6 V
Operating temperature: –40 to +125 °C
🧩 EVM‑Specific Details (ADS131M08EVM)
Purpose: Evaluation of the ADS131M08 8‑channel simultaneous‑sampling ADC
Interface: USB interface to PC (via onboard USB‑to‑SPI bridge)
Included: Board + cables (per Digi‑Key listing)
Power: Typically powered via USB; onboard regulators supply ADC rails
Software: TI provides GUI for configuration, data capture, and register control
