10-BIT, MULTICHANNEL, PARALLEL I/O ADCs FIT IN QSOP PACKAGES
SUNNYVALE, CA—January 22, 2000—Maxim Integrated Products introduces the MAX1090–MAX1093 parallel-interface, 400ksps, 10-bit ADCs. This family of 10-bit ADCs features an 8-bit interface, +3V or +5V single-supply operation, an internal reference, and four or eight input channels. Their small footprint and low current consumption (1.5mA at 100ksps) make them ideal for battery-powered applications.
The analog inputs are software-configurable for unipolar/bipolar and single-ended/differential operation. The full-scale analog input range is determined by the internal +2.5V reference or by an externally applied reference in the 1V-to-VDD range.
The MAX1091/MAX1093 operate from a single +3V analog supply, while the MAX1090/MAX1092 operate from a single +5V analog supply. A VLOGIC pin allows the MAX1090–MAX1093 to interface directly with +1.8V to +5V digital supplies without any additional circuitry. Quiescent current is only 1.5mA at a sample rate of 100ksps; software power-down modes further reduce supply current to less than 10µA at slower sampling rates.
The MAX1090–MAX1093 are available in 24-pin and 28-pin QSOP packages with prices starting from $3.92 (1000-up, FOB USA).
