The ADC0844 and ADC0848 are CMOS 8-bit successive approximation A/D converters with versatile analog input multiplexers. The 4-channel or 8-channel multiplexers can be software configured for single-ended, differential or pseudo-differential modes of operation.
●The differential mode provides low frequency input common mode rejection and allows offsetting the analog range of the converter. In addition, the A/D"s reference can be adjusted enabling the conversion of reduced analog ranges with 8-bit resolution.
●The A/Ds are designed to operate from the control bus of a wide variety of microprocessors. TRI-STATE output latches that directly drive the data bus permit the A/Ds to be configured as memory locations or I/O devices to the microprocessor with no interface logic necessary.
