LM6511IM/NOPB

LM6511IM/NOPB is a precision comparator device for Linear – Comparators. It is supplied in a 14-pin TSSOP package offering features like fast response times and low power consumption. The LM6511IM/NOPB contains two independent comparators suitable for switching applications, noise filtering and transmission applications. It also includes an internal voltage reference, making the device suitable for use in a wide range of applications.

Application field

The LM6511IM/NOPB can be used in a wide range of switching and noise filtering applications. In addition to power supply and AC current monitoring, it can be used in AC/DC power supplies, amplifiers and filters. It is also suitable for use in automotive systems and industrial control devices. Furthermore, the device can be used in opto-electronic device applications.

Working principle

The LM6511IM/NOPB operates on a simple principle. It consists of two independent comparators connected to the input, generating a low output when the inputs are equal or one is greater than the other. When the inputs exceed the traditional range of operation, the output is driven high, resulting in a logic level transition. This principle can be applied in low voltage and high voltage ranges.

The device is designed with a wide range of operating modes suitable for different applications. The outputs are valid even with greater input voltages. The reference voltage is set externally and both hysteresis and Schmitt Trigger functions can be enabled. It also includes an output buffer which can be used to select a digital or analog output.

The LM6511IM/NOPB has a maximum power dissipation of 500mW. The power dissipation can be reduced by using a properly designed circuit. The device is tolerant to input signals up to +/- 5V with a maximum input voltage of 10V. The output can be driven to both supply rails. The output rise and fall times are typically 2.5µs and 0.3µs respectively. The device is also specified with under-voltage lockout and thermal shutdown.

Conclusion

The LM6511IM/NOPB is an ideal choice for Linear – Comparators applications. It offers superior performance, low power consumption and high speeds of operation. In addition to power supply and AC current monitoring, the device is suitable for use in AC/DC power supplies, amplifiers and filters. The two independent comparators, internal voltage reference and output buffer make the device suitable for a wide range of applications.
