Texas Instruments TLV701x & TLV702x Low-Voltage Comparators
Texas Instruments TLV701x and TLV702x Low-Voltage Comparators are micro-power comparators with low-voltage operation and rail-to-rail input capability. The TLV7011/7021 (single-channel) and TLV7012/7022 (dual-channel) are available in an ultra-small, leadless package measuring 0.8mm×0.8mm and standard leaded packages, making them applicable for space-critical designs like smartphones and other portable or battery-powered applications. The Texas Instruments TLV701x and TLV702x Comparators offer an excellent speed-to-power combination with a propagation delay of 260ns and a quiescent supply current of 5µA. This combination of fast response time at micropower enables power-conscious systems to monitor and respond quickly to fault conditions. With an operating voltage range of 1.6V to 5.5V, these comparators are compatible with 3V and 5V systems.
Additional features include no output phase inversion with overdriven inputs and internal hysteresis. These features allow precision voltage monitoring in harsh, noisy environments where slow-moving input signals must be converted into clean digital outputs.
The TLV701x offers push-pull output stages capable of sinking and sourcing milliamps of current when controlling an LED or driving a capacitive load. The TLV702x provides open-drain output stages that can be pulled beyond VCC, making it suitable for level translators and bipolar to single-ended converters.
