+3V, 400ksps, 4/8-Channel,
8-Bit ADCs with 1µA Power-Down
_______________General Description
The MAX113/MAX117 are microprocessor-compatible,
8-bit, 4-channel and 8-channel analog-to-digital con-
verters (ADCs). They operate from a single +3V supply
and use a half-flash technique to achieve a 1.8µs con-
version time (400ksps). A power-down pin (PWRDN)
reduces current consumption to 1µA typical. The
devices return from power-down mode to normal oper-
ating 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.
