The ADC0804LCWM is a CMOS 8-bit successive approximation Analog-to-digital Converter (ADC) that uses a differential potentiometric ladder - similar to the 256R products. This converter is designed to allow operation with the NSC800 and INS8080A derivative control bus with Tri-state output latches directly driving the data bus. These ADCs appear like memory locations or I/O ports to the microprocessor and no interfacing logic is needed. Differential analog voltage inputs allow increasing the common-mode rejection and offsetting the analog zero input voltage value. In addition, the voltage reference input can be adjusted to allow encoding any smaller analog voltage span to the full 8-bit of resolution.
Easy interface to all microprocessors or operates as a stand-alone device
