Texas Instruments ADS1601
The ADS1601 is a high-speed, high-precision, delta-sigma analog-to-digital converter (ADC) manufactured on an advanced CMOS process. The ADS1601 oversampling topology reduces clock jitter sensitivity during the sampling of high-frequency, large amplitude signals by a factor of four over that achieved by Nyquist-rate ADCs. Total harmonic distortion (THD) is –103dB, and the spurious-free dynamic range (SFDR) is 105dB Optimized for power and performance, the ADS1601 dissipates only 330mW while providing a full-scale differential input range of ±0.94VREF.| Part No. | ADS1601 |

DESCRIPTION
Consequently, signal-to-noise ratio (SNR) is particularly improved. Having such a wide input range makes out-of-range signals uncommon. The OTR pin indicates if an analog input out-of-range condition does occur.
