4 Description Con't

The LPV821 amplifier also features an input stage with rail-to-rail input common mode range and an output stage

that swings within 15 mV of the rails, maintaining the widest dynamic range possible. The device is EMI

hardened to reduce system sensitivity to unwanted RF signals from mobile phones, WiFi, radio transmitters, and

tag readers.

The LPV821 zero-drift amplifier operates with a single supply voltage as low as 1.7V, ensuring continuous

performance in low battery situations over the extended temperature range of -40ºC to 125ºC. The LPV821

(single) is available in industry standard 5-pin SOT-23.
