400ksps, +5V, 8-/4-Channel, 10-Bit ADCs with +2.
5V Reference and Parallel Interface
General Description
The MAX1090/MAX1092 low-power, 10-bit analog-todigital converters (ADCs) feature a successive-approximation ADC, automatic power-down, fast wake-up (2µs), an on-chip clock, +2.
5V internal reference, and a high-speed, byte-wide parallel interface.
The devices operate with a single +5V analog supply and feature a VLOGIC pin that allows them to interface directly with a +2.
7V to +5.
5V digital supply.
Power consumption is only 10mW (VDD = VLOGIC) at a 400ksps max sampling rate.
Two software-selectable power-down modes enable the MAX1090/MAX1092 to be shut down between conversions; accessing the parallel interface returns them to normal operation.
Powering down between conversions can cut supply current to under 10µA at reduced sampling rates.
Both devices offer software-configurable analog inputs for unipolar/bipolar and ...
