The ADAQ4001 µModule and ADAQ4003 µModule combine multiple common signal processing and conditioning blocks into a single device that includes a low noise, fully differential analog-to-digital converter (ADC) driver, a stable reference buffer, a high resolution, 16-bit or 18-bit, 2 MSPS successive approximation register (SAR) ADC, and the critical passive components necessary for optimum performance.
The EVAL-ADAQ4001PMDZ and EVAL-ADAQ4003PMDZ on-board components include the following:
• The ADR4550 high precision, buffered bandgap, 5.0V voltage reference
• An optional ADA4898-1 high voltage, low noise, low distortion, unity-gain stable, high-speed op-amp
• An optional AD8251 programmable gain in-amp
• The LT5400-4 quad matched, low drift, resistor network
