VCC = 5V, VEE = –5V, +VS = 5V, VCM = 1V, COUT = 10pF, VSHDN = 0.5V, VOVERDRIVE = 20mV, unless otherwise specified. Note 1: Absolute Maximum Ratings are those values beyond which the life of a device may be impaired. Note 2: If one input is within these common mode limits, the other input can go outside the common mode limits and the output will be valid. Note 3: The LT1719 comparator includes internal hysteresis. The trip points are the input voltage needed to change the output state in each direction. The offset voltage is defined as the average of VTRIP+ and VTRIP–, while the hysteresis voltage is the difference of these two. Note 4: The common mode rejection ratio is measured with VCC = 5V, VEE = – 5V and is defined as the change in offset voltage measured from VCM = – 5.1V to VCM = 3.8V, divided by 8.9V. Note 5: The power supply rejection ratio is measured with VCM = 1V and is defined as the worst of: the change in offset voltage from VEE = – 5V to VEE = 0V divided by 5V, or the change in offset voltage from VCC = + VS = 2.7V to VCC = + VS = 6V (with VEE = 0V) divided by 3.3V. Note 6: Because of internal hysteresis, there is no small-signal region in which to measure gain. Proper operation of internal circuity is ensured by measuring VOH and VOL with only 10mV of overdrive. Note 7: Propagation delay measurements made with 100mV steps. Overdrive is measured relative to VTRIP±. Note 8: tPD cannot be measured in automatic handling equipment with low values of overdrive. The LT1719 is 100% tested with a 100mV step and 20mV overdrive. Correlation tests have shown that tPD limits can be guaranteed with this test, if additional DC tests are performed to guarantee that all internal bias conditions are correct. Note 9: Propagation Delay Skew is defined as: tSKEW = |tPDLH – tPDHL| PIN FUNCTIONS VCC (Pin 1): Positive Supply Voltage for Input Stage. + IN (Pin 2): Noninverting Input of Comparator. – IN (Pin 3): Inverting Input of Comparator. VEE (Pin 4): Negative Supply Voltage for Input Stage and Chip Substrate. GND (Pin 5): Ground. SHDN (Pin 6): Shutdown. Pull to ground to enable comparator. OUT (Pin 7): Output of Comparator. +VS (Pin 8): Positive Supply Voltage for Output Stage. |
