UNISONIC TECHNOLOGIES CO., LTD LMV3011 Preliminary LINEAR INTEGRATED CIRCUIT NANOPOWER, 1.8V, COMPARATOR WITH VOLTAGE REFERENCE 6 DESCRIPTION The UTC LMV3011 is a low-power, open-drain logic compatible output comparator and can provide an independent on-chip voltage reference. The UTC LMV3011 has 5µA (max) quiescent current, and input common-mode range 200mV beyond the supply rails. Single-supply operation can range from 1.8V to 5.5V. The integrated 1.242V series voltage reference with low 100ppm/°C (max) drift is stable with up to 10nF capacitive load, and the output current can be up to 0.5mA (Typ). The UTC LMV3011 is also available in the tiny SOT-26 package for space-conservative designs. The device is specified for the temperature range of -40°C~+125°C. 5 4 1 2 3 SOT-26 FEATURES * Low quiescent current: 5µA (max) * Stable on-chip voltage reference: 1.242V * Voltage reference initial accuracy: ±1% * Reference output current: 0.5mA (Typ) * Input common-mode range: 200mV beyond rails * The lower supply voltage: 1.8V ~ 5.5V * fast response time: 6µs propagation delay with 100mV overdrive (RPULL-UP=10kΩ) ORDERING INFORMATION Note: Ordering Number LMV3011G-AG6-R Pin Assignment: G: Gate D: Drain Package SOT-26 Packing Tape Reel S: Source MARKING www.unisonic.com.tw Copyright © 2014 Unisonic Technologies Co., Ltd 1 of 5 QW-R104-008.a LMV3011 Preliminary PIN CONFIGURATION PIN DESCRIPTION PIN NO. 1 2 3 4 5 6 PIN NAME OUT VIN+ INREF V+ LINEAR INTEGRATED CIRCUIT DESCRIPTION Comparator output.

Absolute maximum ratings are those values beyond which the device could be permanently damaged. Absolute maximum ratings are stress ratings only and functional device operation is not implied. 2. Input terminals are diode-clamped to the power-supply rails. Input signals that can swing more than 0.5V beyond the supply rails should be current limited to 10mA or less. 3.
