Note 3: Applies to both single-supply and split-supply operation. Continuous short circuit operation at elevated ambient temperature can result in exceeding the maximum allowed junction temperature of 150 °C.

Note 9: Do not short circuit the output to V+ when V+ is greater than 12V or reliability will be adversely affected. Note 10: CL includes the probe and test jig capacitance. Note 11: Input offset voltage average drift is calculated by dividing the accelerated operating life VOS drift by the equivalent operational time. This represents worst case input conditions and includes the first 30 days of drift.

APPLICATION INFORMATION

AMS303 is an open collector with a very low supply current of typical 7uA. The advantage of this product is the small space package and simplicity of application. It operates from as low as +2.7V to +15Vand the output pull-up resistor could be biased from higher or lower voltage then Vcc. When a large input signal is applied, an input resistor should be used to limit the input current in case of excessive input voltage. If the input voltage is pulled above the supply voltage Vcc, a set of clamp diode should be used to protect the input circuit. Since AMS303 is a high impedance input, PCB layout precautions should be taken to avoid noise pick-up from adjacent circuits or electrically noisy environments. A good practice is to keep the input traces very short and input components very close to the package. If long conductors are necessary, shielded or twisted pairs should be used.
