Hot-selling and scarce AD7725BSZ 16-Bit ADC with a Programmable Postprocessor QFP44 spot stock

Product Descriptions

The AD7725 is a complete 16-bit,- analog-to-digital converter with on-chip, user-programmable signal conditioning . Theoutput of the modulator is processed by three cascaded finiteimpulse response (FIR) filters, followed by a fully user-programmable postprocessor . The postprocessor provides processingpower of up to 130 million accumulates (MAC) per second . Theuser has complete control over the filter response, the filter coefficients, and the decimation ratio .

The postprocessor permits the signal conditioning characteristics to be programmed through a parallel or serial interface . Itis programmed by loading a user-defined filter in the form of aconfiguration file . This filter can be loaded from a DSP or anexternal serial EPROM . It is generated using a digital filterdesign package called Filter Wizard, which is available from theAD7725 section on the Analog Devices website .
