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.
