The MAX1090/MAX1092 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. 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 single-ended/pseudo-differential operation. In single-ended mode, the MAX1090 has eight input channels and the MAX1092 has four input channels (four and two input channels, respectively, when in pseudo-differential mode).

Excellent dynamic performance and low power, combined with ease of use and small package size, make these converters ideal for battery-powered and data-acquisition applications or for other circuits with demanding power consumption and space requirements.

The MAX1090/MAX1092 tri-states active-low INT when active-low CS goes high. Refer to the MAX1060/MAX1064 if tri-stating active-low INT is not desired.

The MAX1090 is available in a 28-pin QSOP package, while the MAX1092 comes in a 24-pin QSOP. For pin-compatible +3V, 10-bit versions, refer to the MAX1091/MAX1093 data sheet.
