ADC0804LCWM [Texas Instruments]

These are CMOS 8-bit successive approximation ADCs designed for easy interface with 8080-derivative microprocessors without additional logic. They feature differential analog inputs, on-chip clock generator, and operate from a single 5V supply. The devices provide 8-bit resolution with total errors of ±1/4 LSB, ±1/2 LSB, or ±1 LSB and a conversion time of 100 µs. They can be used in ratiometric applications or with external voltage references.
