NOTES:
3. Military temperature range parts are also tested to stated limits at -55oC and 125oC.
4. Guaranteed by characterization but not tested on a production basis.
5. Guaranteed by PSRR test.
6. Refer to FIgure 1. Measured at output amplifier A1 (A1 having zero offset). VREF = +5V. Adjustable to zero with external potentiometer.
Switching Specifications V+ = 5V, TA = 25oC, See Timing Diagram
