open-in-new Find other Comparators

Description

The TLV340x is TI’s first family of nanopower comparators with only 470 nA per channel supply current, which makes this device ideal for battery-powered and wireless handset applications.

The TLV340x has a minimum operating supply voltage of 2.7 V over the extended industrial temperature range (TA = –40°C to +125°C), while having an input common-mode range of –0.1 to VCC + 5 V. The low supply current makes it an ideal choice for battery-powered portable applications where quiescent current is the primary concern. Reverse battery protection guards the amplifier from an overcurrent condition due to improper battery installation. For harsh environments, the inputs can be taken 5 V above the positive supply rail without damage to the device.

All members are available in PDIP and SOIC with the single versions in the small SOT-23 package, dual versions in the VSSOP package, and quad versions in the TSSOP package.
