ST offers the most efficient low-power comparator circuit portfolio on the market, consuming as little as 220 nA per channel, in a variety of space-saving packages such as SOT-23 and SC-70, without sacrificing speed or precision. These attributes allow application designers to extend battery life without loss of performance, in applications where board space is at a premium.
They are also a perfect fit for applications such as window comparators or when additional hysteresis is needed.
Reduced supply leakage for a longer battery lifetime with the TS88 series
The TS881, TS882 and TS884 are respectively single, dual and quad comparators featuring ultra-low supply current with rail-to-rail input and push-pull output capabilities. The new series of open-drain output nanopower comparators also includes a single version ( TS880) and a dual version ( TS883). They feature an ultra-low supply current of 250 nA typical per operator with rail-to-rail input capability and open-drain output. The performance of these comparators allows them to be used in a wide range of portable applications.
Micropower comparator offering 1mm² space saving solution with enhanced dynamic range and high speed
The TS985 is a single micropower low-voltage rail-to-rail comparator. The less than 1 mm², 6-bump chip scale package (CSP) makes the device ideal for space-constrained applications such as smartphones, smartwatches, digital cameras, Internet of Things (IoT) devices, and portable test equipment.
