Description

The MAX1091/MAX1093 low-power, 10-bit analog-to-digital 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. They operate with a single +3V analog supply and feature a VLOGIC pin that allows them to interface directly with a +1.8V to +3.6V digital supply.

Power consumption is only 5.7mW (VDD = VLOGIC) at the maximum sampling rate of 250ksps. Two software-selectable power-down modes enable the MAX1091/ MAX1093 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.
