Description

This TI Verified Design is the realization of a high precision, 16-bit 1MSPS data acquisition system suitable for applications such as digital audio that require front-ends with very low distortion and noise. The circuit uses a high performance Successive Approximation Register Analog to Digital Converter (SAR ADC) and has been optimized to provide superior dynamic performance, without excessive power consumption.

Features
  • Verified Design Contains Theory, Component Selection, TINA-TI Simulation, Altium Schematics and PCB Layout, Measurement Results
  • 16 bit SAR ADC with 1MSPS sampling rate and full-scale input range (FSR) of 4.096V
  • Optmized for AC performance:
    • -110dB measured THD
    •  91.6dB measured SNR
    •  Less than ±0.5LSB INL
