MAX1291, MAX1293 250ksps, +3V, 8-/4-Channel, 12-Bit ADCs With +2.5V Reference And Parallel Interface

The MAX1291 MAX1293 low-power, 12-bit Analog-to-digital 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 They operate with a single +3V Analog supply and feature a VLOGIC pin that allows them to Interface directly with a +1.8V to +5.5V 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 MAX1291 MAX1293 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 MAX1291 has eight input channels and the MAX1293 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 po 883 wer consumption and space requirements.
The MAX1291 MAX1293 tri-states active-low INT when active-low CS goes high. Refer to MAX1261 MAX1263 if tri-stating active-low INT is not desired.
The MAX1291 is available in a 28-pin QSOP package, while the MAX1293 is available in a 24-pin QSOP. For pin-compatible +5V, 12-bit versions, refer to the MAX1290 MAX1292 data sheet.
