Analog Devices Inc. AD4134 Quad-Channel Analog-to-Digital Converters

Analog Devices Inc. AD4134 Quad-Channel Analog-to-Digital Converters (ADCs) are low noise, simultaneous sampling, precision ADCs that offer high functionality, performance, and ease of use. The ADI AD4134 Quad-Channel ADCs are 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. Additionally, the CTSD architecture also inherently rejects signals around the ADC aliasing frequency band, giving the device its inherent antialiasing capability and removing the need for a complicated external antialiasing filter.
