MAX118CPI

P1-P3P4-P6P7-P9P10-P12
_______________General Description
The MAX114/MAX118 are microprocessor-compatible,
8-bit, 4-channel and 8-channel analog-to-digital con-
verters (ADCs). They operate from a single +5V supply
and use a half-flash technique to achieve a 660ns con-
version time (1Msps). A power-down (PWRDN) pin
reduces current consumption typically to 1µA. The
devices return from power-down mode to normal oper-
ating 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 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
MAX114/MAX118 input/reference configuration enables
ratiometric operation.
The 4-channel MAX114 is available in a 24-pin DIP or
SSOP. The 8-channel MAX118 is available in a 28-pin
DIP or SSOP. For +3V applications, refer to the
MAX113/MAX117 data sheet.
