MAX1064

The MAX1060/MAX1064 low-power, 10-bit analog-todigital converters (ADCs) feature a successive-approximation ADC, automatic power-down, fast wake-up (2s), 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 MAX1060/MAX1064 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 10A 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 MAX1060 has eight input channels and the MAX1064 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 dataacquisition applications or for other circuits with demanding power consumption and space requirements.

The MAX1060 is available in a 28-pin QSOP package, while the MAX1064 comes in a 24-pin QSOP. For pincompatible +3V, 10-bit versions, refer to the MAX1061/ MAX1063 data sheet.
