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