AD4134BCPZ

AD4134 is a quad channel, low noise, simultaneous sampling, precision analogue-to-digital converter (ADC) that delivers on functionality, performance and ease of use. Based on the continuous time sigma-delta (CTSD) modulation scheme, the AD4134 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 applications include electrical test and measurement, audio test, 3-phase power quality analysis, control and hardware in loop verification, sonars, condition monitoring for predictive maintenance, acoustic and material science research and development.
