GENERAL DESCRIPTION
The AMS303 has rail-to-rail output swing and input common-mode voltage. It exhibit excellent speed-power ratio, achieving
a Propagation Delay of 400ns with low supply current.
The AMS303 is available in space saving 5-Pin SOT23. The small package saves space on pc boards, and enables the design of
small portable electronic devices. It also allows the designer to place the device closer to the signal source to reduce noise
pickup and increase signal integrity.

Note 1: Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. Operating Ratings indicate conditions for
which the device is intended to be functional, but specific performance is not guaranteed. For guaranteed specifications and the test
conditions, see the Electrical Characteristics.
Note 2: Human body model, 1.5 kin series with 100 pF.
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. Output currents in excess of ±30 mA may adversely affect
reliability.
Note 4: The maximum power dissipation is a function of TJ(max), θJA, and TA. The maximum allowable power dissipation at any ambient
temperature is.
Note 5: PD = (TJ(max) - TA)/ θJA. All numbers apply for packages soldered directly into a PC board.
Note 6: Typical values represent the most likely parametric norm.
Note 7: All limits are guaranteed by testing or statistical analysis.
Note 8: Limiting input pin current is only necessary for input voltages which exceed the absolute maximum input voltage rating.
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.
