The ML2258 is an integrated circuit that combines an 8-bit A/D converter, 8-channel analog multiplexer, 8-bit parallel interface and control logic. The device is suitable for a wide range of applications from process and machine control to consumer, automotive and telecommunications applications. The ML2258 is an enhanced, pin-compatible, second source for the industry standard ADC0808/ADC0809. The ML2258 enhancements are faster conversion time, true sample and hold function, superior power supply rejection, wider reference range, and a double buffered data bus as well as faster digital timing. All parameters are guaranteed over temperature with a power supply voltage of 5V ±10%.
