Product Overview
AD7134 is a quad channel, low noise, simultaneous sampling, precision analog-to-digital converter (ADC) that delivers on functionality, performance, and ease of use. Based on the continuous time sigma-delta (CTSD) modulation scheme, the AD7134 removes the traditionally required switched capacitor circuitry sampling preceding the Σ-Δ modulator, which leads to a relaxation of the ADC input driving requirement. The CTSD architecture also inherently rejects signals around the ADC aliasing frequency band, giving the device its inherent antialiasing capability, and removes the need for a complex external antialiasing filter. Typical application includes electrical test and measurement, audio test, 3-phase power quality analysis, control and hardware in loop verification, sonars condition monitoring for predictive maintenance and acoustic and material science research and development.
- Alias free: inherent antialias rejection high performance mode 102.5dB, typical
- 108/137dB dynamic range at ODR = 374KSPS/10SPS, FIR filter/sinc3 filter, typical
