Intersil's pinPOINT(TM) Line Launches World's Lowest Power Op Amp
Intersil's pinPOINT(TM) Product Line's New Family of Nano-Power, Single-Supply Precision Op Amps and Comparators Achieves Industry's Best Supply Current Consumption at 450nA (Max)
MILPITAS, CA, July 5, 2007 - Intersil Corporation (NASDAQ Global Select: ISIL), a world leader in the design and manufacture of high-performance analog semiconductors, today announced a new family of power-efficient, rail-to-rail input/output operational amplifiers and comparators that includes the new industry leader in power efficiency. The ISL28194 boasts an industry's best supply current rating of just 330nA typical and 450nA maximum - less than half the supply current consumption of any competitive device.
This family, part of Intersil's new pinPOINT(TM) Precision Analog Product Line, also includes an op amp that delivers more bandwidth and typically consumes 1 microamp of supply current (ISL28195) and two comparators that typically consume 800nA (ISL28197) and 2.5 microamps (ISL28196).
A single-supply input voltage range from 1.8V to 5.5V makes this entire family ideal for low-power precision applications running off of two 1.5V alkaline batteries such as smoke detectors; toxic gas detectors; and temperature, humidity and pressure sensor/monitors. Other target applications include low-power solar cell devices.
These devices are designed to deliver unmatched battery savings and extended operation. First, their supply current ratings mean they consume less power while the devices are in operation. Second, the devices feature an enable/disable pin that can throttle the power consumption down to just 2nA when not in use. Operation is further extended by the input common mode range of these devices that extends all the way to the positive and negative input rail. This true rail-to-rail performance enables the op amp to consume more of a battery's available energy.
