Linear Tech 3.2 MHz Dual Micropower Comparator Operates Below 2V With 60µA IqOctober 01, 2007 by Jeff Shepard
Linear Technology Corp. announced the LTC6702, a fast, micropower dual comparator in a 2mm x 2mm DFN package. With operation down to 1.7V and less than 60µA of maximum current consumption, this tiny device is suitable for portable and battery operated equipment. Low voltage operation is supported by the LTC6702’s input common mode range, which extends 100mV below ground. Despite its low power consumption, the LTC6702 can switch with a toggle rate of 3.2MHz and offers a propagation delay of less than 500ns.
The LTC6702 is claimed to offer excellent precision – input bias current is typically 1pA and the offset voltage is guaranteed to be less than 3.5mV. The built-in comparator hysteresis and guaranteed specifications from Ã¢ï¿½ï¿½40 to 125°C ensure reliable operation in electrically noisy and high temperature environments. In addition, the LTC6702 offers a robust output drive of ±15mA and can drive capacitive loads up to 10,000pF.
"The LTC6702 offers a great combination of speed, power, size and output drive," stated Brendan Whelan, Design Manager for Linear Technology. "The versatility of this part is an ideal match for low voltage and battery-operated electronics."
The LTC6702 is in full production, with prices starting at $0.96 each in 1,000-piece quantities.
