AD53041–SPECIFICATIONS (All specifications apply at T

J = +85 C

5 C. +VS = +10.5 V

3%, –VS =

–5.2 V

3% unless otherwise specified. VCOMOUT is bypassed to ground with a series RC consisting of a 1

resistor and a 0.1

F capacitor,

and is also connected directly to OUT_SENSE. All temperature coefficients are characterized over TJ = 75 C–95 C.)
