The TLV3404CDR is a high-accuracy linear voltage comparator, specifically designed to operate from a single supply rail. The TLV uses current feedback from an opamp stage connected to current mirrors driven by the output, to provide excellent linearity over the entire operating range. This makes the TLV ideal for low-distortion applications such as audio, video, and other mixed-signal processing.

The device offers 100 mV hysteresis and an optional high voltage supply input for operation up to ±10 V. This allows for wide operating range, which is beneficial for applications such as video and audio. Additionally, the low offset and wide common mode range of the TLV3404CDR is ideal for low jitter and high-precision performance. In addition, the device is specified over the extended industrial temperature range of -40°C to +125°C.

The TLV3404CDR is available in SO-8, MSOP-8, SOIC-8 and TSSOP-8 packages, making it suitable for a wide variety of applications. The device has a single-supply voltage operation, capable of operating with a supply voltage as low as 1.8 V and is capable of sinking up to 50 mA of current. It is also designed with an open-drain output, meaning that the output voltage can be driven above, below or within the supply voltage.

The TLV3404CDR is suitable for applications requiring accurate threshold detection, such as power management and sequence control, as well as many audio, video and mixed-signal processing applications, due to its low power and high linearity. The device can be used for applications such as temperature sensing, overvoltage protection, and window comparators, and can also be used in conjunction with other comparators, such as the TLV3501 and TLV7520.

The TLV3404CDR working principle is based on current feedback. The input pins of the device are connected to current mirrors, while the output pin is connected to a voltage follower circuit. The voltage feedback is provided by the voltage follower circuit. The outputs of the current mirrors are also connected to an opamp stage, which provides the current feedback to the device. This current feedback is used to control the output voltage of the comparator, resulting in the device’s excellent linearity over the entire operating range. Additionally, the device has an open-drain output, allowing the output voltage to be driven above, below or within the supply voltage.

In summary, the TLV3404CDR is well suited for a wide range of applications requiring low-distortion performance, including power management and sequence control, temperature sensing, overvoltage protection, and window comparators. The device’s low jitter and wide common mode range provide excellent linearity over the entire operating range, and it is capable of sinking up to 50 mA of current. The device’s current feedback working principle provides it with excellent linearity, and its open-drain output allows for greater flexibility in the applications it can be used for.
