♦ +3.0V to +3.6V Single-Supply Operation

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)

re d uc e s c urre nt c ons ump tion to 1µA typ ic a l. 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.

♦ 4 (MAX113) or 8 (MAX117) Analog Input Channels

♦ Low Power: 1.5mA (operating mode)

1µA (power-down mode)

♦ Total Unadjusted Error ≤ 1LSB

♦ Fast Conversion Time: 1.8µs per Channel

♦ No External Clock Required

♦ Internal Track/Hold

♦ Ratiometric Reference Inputs

♦ Internally Connected 8th Channel Monitors

Reference Voltage (MAX117)

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.
