TEST AND MEASUREMENT PRODUCTS
AC Characteristics (continued)
2005 Semtech Corp. / Rev. 5, 11/30/05
Settling times are not production tested. Guaranteed by characterization.
Measured from full-scale step at VINP to FORCE output.
Test Conditions:
1. 15 pF load on output
2. input signal has 5 ns rise/fall time
3. tpd is defined as the difference between the time when the input crosses 1.5V to when the output
changes 10% (of the total change) from the initial voltage level. (see timing diagram below).
Measured from full-scale step at VINP to IVMON output.
Clamp activation/recovery time indicates the delay between when the clamps are actually engaged
or disengaged and when clamping is indicated with the comparator outputs.
Comparator Propagation Delay Measurements.
HiZ=1, MI/MV*=0, SELIPMU=1, input signal applied to FORCE/SENSE.
