LMV604MT/NOPB is a dual operational amplifier that combines high performance, low power consumption, high speed and low noise level in a small 8-pin package. It is designed to provide ample gain, excellent small signal linearity, and high output drive current. It is widely used in applications such as instrumentation, buffering, sample-and-hold circuits, data acquisition, and level shifting.

Instrumentation applications:

LMV604MT/NOPB device is suitable for many kinds of general-purpose instrumentation applications such as thermometers, force transducers, flow measurements, pressure measurements, and data acquisitions. The high slew rate, low noise, and low power features are beneficial for these applications. In addition, its great accuracy ensures accurate measurements.

For instance, in a thermometer application, LMV604MT/NOPB is used to provide a differential voltage output from the sensed voltage from a thermocouple. The device is then connected to an ADC or buffer amplifier to convert the output to a digital value for further computation. In this case, the LMV604MT/NOPB’s low-input bias current and low noise performance are critical to ensure accurate temperature measurements.

Op-amps:

LMV604MT/NOPB has a wide range of current gain bandwidth product, wide common-mode range, low offset voltage and drift, and low input bias current. All these features enable the device to be used in non-inverting amplifiers, inverting amplifiers, summing amplifiers, and differential amplifiers. It is also suitable for applications such as active filters, buffer amplifiers and gain control stages.

In addition, its excellent drift characteristics, high slew rate and low distortion make it an ideal choice for applications where a high degree of precision is required. For example, when operating as a differential amplifier in an active low pass filter for measuring the speed of an object, its high slew rate works perfectly to filter out unwanted signals and accurately measure the input frequency.

Buffer amplifiers:

LMV604MT/NOPB device is also used as a buffer amplifier in buffering applications where high-speed output response, low power consumption and small size are necessary. For example, it is used in video and audio buffer amplifiers, level shifters, and data separators as a driver because of its high two-level output swing feature. It is also used to drive LED displays, LCD screens, and stepper motors because of its low power consumption.

Working principle:

The LMV604MT/NOPB is an internally compensated dual operational amplifier with a common-mode input voltage range from ground to a maximum of 6.5V. It has a maximum supply voltage of 7V and a quiescent current of less than 5mA. The device consists of two identical amplifier stages which are internally connected, with each stage having the same input and output stage configurations.

The LMV604MT/NOPB has a differential gain bandwidth product of 250kHz and a high slew rate of 100V/μs. It has on-chip temperature compensating circuitry and thermal shutdown protection, ensuring stable and reliable operation. It also provides high output drive current, up to 10mA each, making it suitable for driving heavier loads. Furthermore, the LMV604MT/NOPB is designed to be immune to latch-up and static discharge.
