MAX113 - +3V / 400ksps / 4/8-Channel / 8-Bit ADCs

General Description

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 1.8µs conversion time (400ksps).

A power-down pin (PWRDN) reduces current consumption to 1µA typical.

19-1081; Rev 1; 8/96 +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 converters (ADCs). They operate from a single +3V supply and use a half-flash technique to achieve a 1.8µs conversion time (400ksps). A power-down pin (PWRDN) reduces current consumption to 1µA 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.
