MAX113:+3V、400ksps、4/8通道、8位ADC,带有1µA关断模式

低功耗、+3V、8位ADC,并行接口

The MAX113/MAX117 are microprocessor-compatible, 8-bit, 4-channel and 8-channel analog-to-digital converters (ADCs). They operate from a single +3V supply and use a half-flash technique to achieve a 1.8µs conversion time (400ksps). A power-down pin (active-low PWRDN) reduces current consumption to 1µA typical. The devices return from power-down mode to normal operating mode in less than 900ns, 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 analog input signals.) Both converters include a track/hold, enabling the ADC to digitize fast analog signals. 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 8-bit parallel µP data bus or system input port. The MAX113/MAX117 input/reference configuration enables ratiometric operation. The 4-channel MAX113 is available in a 24-pin DIP or SSOP. The 8-channel MAX117 is available in a 28-pin DIP or SSOP. For +5V applications, refer to the MAX114/MAX118 data sheet.
