This standard device has proven ubiquity and versatility across a wide range of applications. This is due to its low power and high speed. The open-drain output allows the user to configure the output's logic low voltage (VOL) and can be utilized to enable the comparator to be used in AND functionality. V+ IN+ IN- + OUT - V- Figure 1. Functional Block Diagram 11 www.run-ic.com RS331, RS393, RS339 Application and Implementation Application Information RS331, RS393 and RS339 will typically be used to compare a single signal to a reference or two signals against each other. Many users take advantage of the open drain output (logic high with pull-up) to drive the comparison logic output to a logic voltage level to an MCU or logic device. Typical Application VLOGIC VLOGIC VSUP VIN VSUP RPULLUP + VIN+ RS331 RPULLUP + RS331 Vref VIN- Figure 2. Typical Application Schematic Power Supply Recommendations For fast response and comparison applications with noisy or AC inputs, it is recommended to use a bypass capacitor on the supply pin to reject any variation on the supply voltage. This variation causes temporary fluctuations in the comparator's input common mode range and create an inaccurate comparison. Layout Layout Guidelines For accurate comparator applications without hysteresis it is important maintain a stable power supply with minimized noise and glitches, which can affect the high-level input common mode voltage range. In order to achieve this, it is best to add a bypass capacitor between the supply voltage and ground. This should be implemented on the positive power supply and negative supply (if available). If a negative supply is not being used, do not put a capacitor between the IC's GND pin and system ground.
