The LMP7702MMX/NOPB is a versatile, high-performance linear amplifier commonly used in a wide variety of instrumentation and buffer applications. This linear amplifier is capable of operating over a wide range of supply voltages and cutoff frequencies. The LMP7702MMX/NOPB is designed to provide high current drive, low noise operation, and exceptional stability and accuracy.

The LMP7702MMX/NOPB is a high performance, wide band, low-power amplifier designed specifically for low-power consumption and low voltage applications. It features a flat frequency response from DC to beyond the 1-GHz limit. The device features nearly flat gain from DC up to GHz frequencies, providing for a low-noise, high-resolution amplifier solution that can broaden dynamic range. It operates with a supply voltage range of 3 V to 15 V, and only consumes a 2-mA quiescent current. The LMP7702MMX/NOPB also has an excellent power supply rejection ratio of -68 dB.

The LMP7702MMX/NOPB amplifier is well suited for general purpose or instrumentation applications, such as biomedical instrumentation, instrumentation amplifiers, and audio amplifiers. The device can also be used as a buffer amplifier or a driver amplifier in voltage-sensing and logic circuits. The device is well suited for low-noise, low-power applications such as medical diagnostic systems, dental instruments, and audio systems.

The working principle of the LMP7702MMX/NOPB is based on a standard single-stage, differential amplifier design using two matched N-channel junction field effect transistors (JFET). The differential input signals are applied to the gate terminals of the JFETs, which provide excellent input impedance and low distortion. The tail current is then adjusted to provide the desired output level.

The differential gain of the amplifier is determined by the choice of the resistor values in the feedback network. The differential output can be either summed or inverted, depending on the feedback network. The input capacitance (Cin) of the amplifier is significantly reduced compared to other amplifiers, which results in lower noise.

The overallgain accuracy of the amplifier is also improved, since the input and output switches are controlled digitally with a logic low voltage level. This also reduces power dissipation, since the logic low level consumes less power than a logic high level.

The LMP7702MMX/NOPB is an excellent choice for a wide range of instrumentation and buffer amplifier applications. The amplifier features a high current drive, low noise operation, and exceptional stability and accuracy. The device is extremely power efficient and features a high power supply rejection ratio. With an operating voltage range of 3 V to 15 V and a quiescent current of only 2 mA, the device is ideal for low-power and low-voltage applications.
