The TLV340x has a minimum operating supply voltage of 2.7 V over the extended industrial temperature range (TA = 40C to 125C), 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 over-current 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.
