LTC1041 ELECTRICAL CHARACTERISTICS V Note 5: R Note 3: SET POINT error ≡ – SET POINT U + VL ( ) IN is guaranteed by design and is not tested. 2 RIN = 1/(fS x 66pF). where V Note 6: Average supply current = t U = upper band limit and VL = lower band limit. D • IS(ON) • fS + (1 – tD • fS) lS(OFF). Note 7: Response time is set by an internal oscillator and is independent Note 4: Deadband error ≡ (VU – VL) – 2 • DELTA where VU = upper band of overdrive voltage. t limit and V D = VP-P pulse width. L = lower band limit. Note 8: Output also capable of meeting EIA/JEDEC standard B series CMOS drive specifications.
