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 1.8s conversion time (400ksps). A power-down pin (PWRDN) reduces current consumption to 1A typical. The devices return from power-down mode to normal operating mode in less than 900ns, allowing large supplycurrent 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 (P) 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 P 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. |
