+5V, 1Msps, 4 & 8-Channel,

8-Bit ADCs with 1µA Power-Down

_______________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.
