19-2719; Rev 0; 04/03 MAX1261/MAX1263 250ksps, +3V, 8-/4-Channel, 12-Bit ADCs with +2.5V Reference and Parallel Interface General Description The MAX1261/MAX1263 low-power, 12-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. 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 softwareselectable power-down modes enable the MAX1261/ MAX1263 to...
