www.DataSheet4U.com CS4373A Low-power, High-performance ∆Σ Test DAC Features ∆Σ Input from CS5376A Digital Filter z Selectable Differential Analog Outputs z Digital Description The CS4373A is a high-performance, differential output digital-to-analog converter (DAC) with programmable attenuation and multiple operational modes. AC test modes measure system dynamic performance through THD and CMRR tests while DC test modes are for gain calibration and pulse tests. The CS4373A is driven by a ∆Σ digital bit stream from the CS5376A digital filter test bit stream (TBS) generator. It has two sets of differential analog outputs, OUT and BUF, to simplify system design as dedicated outputs for testing the electronics channel and for in-circuit sensor tests. Analog output attenuation is selected by simple pin settings and matches the gain of the CS3301A / CS3302A differential amplifiers for full-scale testing at all gain ranges. calibration capability for high-resolution, low-frequency multi-channel measurement systems designed from CS3301A / CS3302A differential amplifiers, CS5371A / CS5372A ∆Σ modulators and the CS5376A digital filter.
