COMPARATORS PLUS 6ppm/°C REFERENCE IN TINY SOT23

SUNNYVALE, CA-January 22, 2000—Maxim Integrated Products introduces the MAX9040/MAX9050 micropower comparators with Rail-to-Rail inputs and outputs, plus an onboard precision reference, packed in 5-pin SOT23 packages. Ideal for battery voltage monitoring, these precision devices maximize battery life by eliminating premature end-of-life readings common in voltage monitors with large errors. These devices also offer 0.4% initial accuracy (A grade only) with a 6ppm/°C temperature coefficient and a fast 400ns propagation delay while consuming a miserly 40µA of supply current. The reference can drive 500µA and is stable with any capacitive load up to 4.7nF.

The MAX9040 operates from a +2.5V to +5.5V supply and provides a reference voltage of 2.048V, which represents a 500µV LSB in 12-bit systems. The MAX9050 operates from a +2.7V to +5.5V supply and provides a 2.500V reference voltage. All comparators feature internal hysteresis and crowbar current limiting, which reduces current consumption while switching at high frequencies. Prices start from $0.96 (B grade) (1000-up, FOB USA).
