LMV761MAX Application Field and Working Principle

The LMV761MAX is one of the linear-comparators developed by Texas Instruments. It is an ultra-low power single-channel comparator that requires low quiescent current of 5 µA. This differential input device has a shutdown feature that helps reduce the current consumption to 400 nA in shutdown mode. It also has a rail-to-rail output voltage swing and a low output saturation voltage. The LMV761MAX is available in two package options, such as the Ultra small SC70 and the SOT-23. It is also available in lead -free ECO planar package options.

Characteristics of the LMV761MAX

The LMV761MAX differential input voltage range of ±12 V offers superior fidelity in comparison to other comparators that offer differential voltage range of 0 V to +Vcc. Its hysteresis allows for wide common mode noise rejection over a broad temperature range of -40°C to +125°C. This comparator has an input bias current of 2nA and a large overdrive voltage of 10 V. The device\'s common mode-rejection ratio is 70 dB and open-loop gain is 100 dB. The LMV761MAX offers a wide supply voltage range of 4 V to 16 V that is ideal for battery-operated applications. It has a propagation delay of 4 µs max, which makes it ideal for low power systems. The device is also robust in high temperature environments, operating satisfactorily up to 150°C. It also has a junction temperature tolerance of up to 165°C.

LMV761MAX Application Fields

The LMV761MAX is an ideal device for applications that require a high common mode range. It is widely used in low power systems such as handheld medical devices. It is also used in battery-operated systems such as smoke detectors, vehicle electronics, and gas sensors. It is also suitable for automotive security systems that require high robustness in high temperature environments. Other applications of this device include smart phones, tablets, hearing aid and wearables.

Working Principle

The LMV761MAX device operates by comparing the input voltages at its positive and negative terminals. It then produces an output voltage that is inversely proportional to the difference between the two inputs. Its outputs are either in the form of logic LOW or HIGH signals. For example, if the inputs are at the same potential, the output logic level will be LOW. On the other hand, if the two inputs are different, the output will be logic HIGH.The LMV761MAX also has a shut-down feature that allows the user to reduce its power consumption by reducing the current flow. When the device is shut down, the output becomes HIGH impedance and the total current drawn by the device is reduced to 400 nA. This feature ensures that the LMV761MAX does not consume more power than necessary.The LMV761MAX is a versatile device that offers excellent performance for a wide range of applications. Its low power consumption and extremely small package size make it ideal for battery-operated and portable electronic devices. Its wide common mode rejection range also makes it suitable for applications with high levels of noise. In addition, its low output saturation voltage and Propagation delay of 4 µs max make it suitable for low power systems. Overall, the LMV761MAX is an ideal choice for applications that need low power and wide common mode rejection. Its robust performance, wide temperature range and high common mode-rejection ratio make it suitable for a broad range of applications.
