ADI AD4134BCPZ-RL7

The AD4134 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 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. The AD4134 has four independent converter channels in parallel, each with a CTSD modulator and a digital decimation and filtering path. The AD4134 enables simultaneous sampling of four separate signal sources, each supporting a maximum input bandwidth of 391.5 kHz and achieving tight phase matching between these four signal measurements. The high level of channel integration, together with its simplified analog front-end requirement, enables the AD4134 to provide a high density multichannel data acquisition solution in a small form factor. The signal chain simplification property of the AD4134 also improves the system level performance through the reduction of noise, error, mismatch, and distortion that is normally introduced by the ana
