Single-channel comparator extends battery life in low-voltage portable devices

The single-channel device consumes 6 μA and provides guaranteed operation from 1.6 V up to 5.5 V, making it well-suited for use in systems with nominal supplies of 1.8 V, 3.0 V or 5.0 V, such as mobile phones, tablets and notebook computers, where the device delivers superior performance and helps extend battery life.

The comparator features internal hysteresis in order to provide immunity to undesirable small voltage fluctuations, and uses a complementary output stage, comprising P- and N-channel MOSFETS, in order to drive outputs with a full rail-to-rail voltage swing. Miniaturized package options help reduce PCB board space: the AZV3001 is offered in a 6-pin X2-DFN1410-6 package and the dual-channel AZV3002, available later in 2015, in an 8-pin U-FLGA1616-8 package.

With a low propagation delay of 0.8 μs, a low input bias current of 1 pA and no risk of phase inversion when the input is overdriven, these comparators offer embedded system design engineers a general-purpose solution to almost all low-voltage portable device requirements.

Availability and Pricing

The single-channel AZV3001 is available now and is priced at $0.15 each in 10k piece quantities. The dual-channel AZV3002 will be priced at $0.30 each.
