The MAX118CAI+ is a +5V, 1Msps, 8-channel, 8bit analogue to digital (ADC) converter with 1µA power down in 28 pin SSOP package. It operate from a single supply and use a half-flash technique to achieve a 660ns conversion time (1Msps). The microprocessor (µP) interfaces are simplified because the ADC can appear as a memory location or I/O port without external interface logic. The data outputs use latched, three-state buffer circuitry for direct connection to an 8bit parallel µP data bus or system input port. A power-down (PWRDN - complementary) pin reduces current consumption typically to 1µA. The device return from power-down mode to normal operating mode in less than 200ns, allowing large supply current reductions in burst-mode applications (in burst mode, the ADC wakes up from a low power state at specified intervals to sample the analogue input signals). it include a track/hold, enabling the ADC to digitize fast analogue signals.
