WS72321 WS72321 Low-Power Rail-to-Rail Operational Amplifiers Input Output Http//:www.willsemi.com Descriptions The WS72321 series is a single low-voltage operational amplifier with rail-to-rail input/output swing. SOT353 SOT23-5L Ultra low quiescent current makes this amplifier ideal for portable, battery operated equipment. The common mode input range includes ground making the device useful for low−side current−shunt measurements. The ultra small packages allow for placement on the PCB in close proximity to the signal source thereby reducing noise pickup. SOT23-5L SOT353 （WS72321EO-5/TR） （WS72321B-5/TR） & SOT23-5L The WS72321 is available with MSL 3 Level in （ WS72321E-5/TR） SOT353(SC70-5L) package and SOT23-5L package. Pin configuration (Top view) Standard products are Pb-Free and halogen-Free.

Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. Exposure to any Absolute Maximum Rating condition for extended periods may affect device reliability and lifetime. 2. A heat sink may be required to keep the junction temperature below the absolute maximum rating when the output is shorted indefinitely. 3. Thermal resistance varies with the amount of PC board metal connected to the package. The specified values are for short traces connected to the leads. 4. Full power bandwidth is calculated from the slew rate FPBW = SR/(π • VP-P).
