ADS1602 相关产品

The ADS1602 is a high-speed, high-precision, delta-sigma analog-to-digital converter (ADC) manufactured on an advanced CMOS process. The ADS1602 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. Consequently, signal-to-noise ratio (SNR) is particularly improved. Total harmonic distortion (THD) is -101dB, and the spurious-free dynamic range (SFDR) is 103dB.

Optimized for power and performance, the ADS1602 dissipates only 530mW while providing a full-scale differential input range of ±3V. Having such a wide input range makes out-of-range signals unlikely. The OTR pin indicates if an analog input out-of-range condition does occur.
