MAX118 - +5V / 1Msps / 4 & 8-Channel / 8-Bit ADCs

General Description

The MAX114/MAX118 are microprocessor-compatible, 8-bit, 4-channel and 8-channel analog-to-digital converters (ADCs).

They operate from a single +5V supply and use a half-flash technique to achieve a 660ns conversion time (1Msps).

19-1083; Rev 1; 8/96 +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 converters (ADCs). They operate from a single +5V supply and use a half-flash technique to achieve a 660ns conversion time (1Msps). A power-down ( PWRDN ) pin reduces current consumption typically to 1µA. The devices return from power-down mode to normal operating mode in less than 200ns, 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.
