The comparators feature less than.µa supply current over temperature, an internal reference (.V ±% for LTC or.v ±% for LTC/LTC), programmable hysteresis (LTC/LTC) and TTL/CMOS output (LTC/ LTC) that sinks and sources current (open-drain output for LTC). The reference output can drive a bypass capacitor of up to.µf without oscillation. The comparators operate from a single V to V supply or a dual ±V to ±.V supply (LTC). Comparator hysteresis is easily programmable using two resistors and the HYST pin (LTC/LTC). Each comparator s input operates from the negative supply to within.v of the positive supply. The LTC/LTC comparator output stage can continuously source up to ma. By eliminating the cross-conducting current that normally happens when the comparator changes logic states, power supply glitches are eliminated. The LTC/LTC/LTC are available in the -pin SO, PDIP and DFN packages.

Applications Information The LTC/LTC/LTC is a family of quad micropower comparators with a built-in reference (.V for the LTC and.v for the LTC/LTC). Features include programmable hysteresis (LTC/ LTC), wide supply voltage range (V to V) and the ability of the reference to drive up to a.µf capacitor without oscillation. The comparator CMOS outputs (LTC/ LTC) can source up to ma while the LTC has an open-drain output to V. The supply current glitches that normally occur when the comparator output switches states have been eliminated. Power Supplies The comparator family operates from a single V to V supply. The LTC includes a separate ground for the comparator output stage, allowing a split supply ranging from ±V to ±.V. Connecting V to GND on the LTC allows single supply operation. If the comparator output is required to source more than ma or the supply source impedance is high, V should be bypassed with a.µf capacitor. IN D (Pin ): Noninverting Input of Comparator D. Input common mode range from V to V.V. Input current typically pa at C. GND (Pin ): LTC Ground. Connect to V for single supply operation. HYST (Pin ): LTC/LTC Hysteresis Input. Connect to if not used. Input voltage range is from V to V mv. OUT D (Pin ): Comparator D Output. (Open-drain output for LTC). Output can source up to ma (LTC, LTC) and sink ma. OUT C (Pin ): Comparator C Output. (Open-drain output for LTC). Output can source up to ma (LTC, LTC) and sink ma. Exposed Pad (Pin 7, DFN Package): This pin is internally connected to V. Connection is optional, but will improve thermal dissipation. Comparator Inputs The comparator inputs can swing from the negative supply (V ) to within.v maximum of the positive supply (V ). The inputs can be forced mv below V or above V without damage, and the typical input leakage current is only ±pa. Comparator Outputs The LTC comparator output swings between GND and V to assure TTL compatibility with a split supply. The LTC and LTC outputs swing between V and V. The outputs are capable of sourcing up to ma (LTC/ LTC) and sinking up to ma while still maintaining microampere quiescent currents. The output stage does not generate crowbar switching currents during transitions which helps minimize parasitic feedback through the supply pins. Voltage Reference The internal bandgap reference has a voltage of.v for LTC or.v for LTC/LTC referenced to fd

9 Applications Information V. The reference accuracy is.% from C to C. It can source up to µa and sink up to µa with a V supply. The reference can drive a bypass capacitor of up to.µf without oscillation and by inserting a series resistor, capacitance values up to µf can be used (Figure ). Figure shows the resistor value required for different capacitor values to achieve critical damping.

Damping Resistance vs Bypass Capacitor Value Bypassing the reference can help prevent false tripping of the comparators by preventing glitches on the V or the reference output voltage. Figure shows the bypassed reference output with a square wave applied to the V pin. Resistors R and R set mv of hysteresis, while R damps the reference response. Note that the comparator output doesn t trip. Hysteresis Hysteresis can be added to the LTC/LTC by connecting a resistor (R) between the and HYST pins, and a second resistor (R) from HYST to V (Figure ). Figure b. V Glitching Response V R = HB I ()(I ) R R LTC HYST F Figure. Programmable Hysteresis The difference between the upper and lower threshold voltages or hysteresis voltage band (V HB ) is equal to twice the voltage difference between the and HYST pins. When more hysteresis is added, the upper threshold increases the same amount as the lower threshold decreases. The maximum voltage allowed between and HYST is ( ) V HB.V R = I fd

Acceptable values for I range from.µa to µa. If.M is chosen for R, then R(kΩ) = V HB (mv). Level Detector The LTC is ideal for use as a multisupply micropower level detector as shown in Figure.
