Product Summary

The ADC0844CCN is a CMOS 8-bit successive approximation A/D converter with versatile analog input multiplexers. The ADC0844CCN 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 ADC0844CCN is 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/D to be configured as memory locations or I/O devices to the microprocessor with no interface logic necessary.
