LPV7215MG

LPV7215 580 nA Rail-to-Rail Input and Output, 1.8V Push-Pull Output Comparator PRELIMINARY September 2005 LPV7215 580 nA Rail-to-Rail Input and Output, 1.8V, Push-Pull Output Comparator General Description The LPV7215 is an ultra low-power comparator with a typical power supply current of 580 nA. It has the best-in-class power supply current versus propagation delay performance available among National’s low-power comparators. The propagation delay is as low as 4.5 microseconds with 100 mV overdrive at 1.8V supply. Designed to operate over a wide range of supply voltages, from 1.8V to 5.5V, the LPV7215, with guaranteed operation at 1.8V, 2.7V and 5.0V, is ideal for use in a variety of battery-powered applications. With rail-to-rail common mode voltage range, the LPV7215 is well suited for single-supply operation. Featuring a push-pull output stage, the LPV7215 allows for operation with absolute minimum power consumption when driving any capacitive or resistive load. With an operating temperature range of −40˚C to 125˚C, this comparator can be adopted for extreme temperature applications. Available in a choice of space-saving packages, the LPV7215 is ideal for use in handheld electronics and mobile phone applications. The LPV7215 is manufactured with National’s advanced VIP50 process.

Operating Ratings indicate conditions for which the device is intended to be functional, but specific performance is not guaranteed. For guaranteed specifications and the test conditions, see the Electrical Characteristics Tables. Note 2: Human body model, 1.5 kΩ in series with 100 pF. Machine model: 0Ω in series with 200 pF. Note 3: The maximum power dissipation is a function of TJ(MAX), θJA, and TA. The maximum allowable power dissipation at any ambient temperature is PD = (TJ(MAX) - TA)/ θJA . All numbers apply for packages soldered directly onto a PC board at the time of characterization. Note 4: Typical values represent the most likely parametric norm. Note 5: Limits are 100% production tested at 25˚C. Limits over the operating temperature range are guaranteed through correlations using statistical quality control (SQC) method. Note 6: Positive current corresponds to current flowing into the device. Note 7: Offset voltage average drift determined by dividing the change in VOS at temperature extremes into the total temperature change. Note 8: Electrical table values apply only for factory testing conditions at the temperature indicated. Factory testing conditions result in very limited self-heating of the device. www.national.com 4 LPV7215 Connection Diagram SC70/SOT23 20123698 Top View Ordering Information Package 5-Pin SOT-23 5-Pin SC70 Part Number LPV7215MF LPV7215MFX LPV7215MG LPV7215MGX Package Marking C30A C37 Transport Media 1k Units Tape and Reel 3k Units Tape and Reel 1k Units Tape and Reel 3k Units Tape and Reel NSC Drawing MF05A MAA05A 5 www.national.com LPV7215 Physical Dimensions inches (millimeters) unless otherwise noted 5-Pin SOT23 NS Package Number MF05A 5-Pin SC70 NS Package Number MAA05A www.national.com 6 LPV7215 580 nA Rail-to-Rail Input and Output, 1.8V Push-Pull Output Comparator Notes National does not assume any responsibility for use of any circuitry described, no circuit patent licenses are implied and National reserves the right at any time without notice to change said circuitry and specifications.
