LMH6517SQ/NOPB Digital Variable Gain Amplifier

The LMH6517SQ/NOPB from Texas Instruments is a high-performance, digitally controlled variable gain amplifier (DVGA) designed to offer a versatile combination of bandwidth, gain, and linearity for a wide range of applications. This component is part of Texas Instruments' PowerWise® family, which emphasizes energy-efficient solutions without compromising on performance.

With an impressive bandwidth of 900 MHz and a programmable gain range of -16.5 dB to +22 dB, the LMH6517SQ/NOPB is capable of handling high-speed signals while providing precise gain control. This is achieved through a serial control interface that allows for 0.5 dB gain step resolution, enabling fine-tuning for optimal signal amplitude levels.

The device's exceptional linearity, with a third-order intercept point (OIP3) of 46 dBm at 200 MHz, makes it suitable for applications that require high dynamic range, such as test and measurement equipment, medical imaging systems, and communication infrastructure. Its noise figure of 10.2 dB at maximum gain ensures that signal integrity is maintained even under challenging conditions.

The LMH6517SQ/NOPB operates over a single 5V supply and features an enable/disable function that allows the user to power down the device when not in use, further conserving energy. The package is a 24-pin WQFN, which is optimal for space-constrained applications.

Moreover, the NOPB designation in the product name indicates that this device is lead-free and RoHS compliant, reflecting Texas Instruments' commitment to environmental sustainability. The reliability and quality of the LMH6517SQ/NOPB are backed by Texas Instruments' reputation as a leading manufacturer in the semiconductor industry.

Whether for data acquisition systems, wireless communication, or radar and satellite subsystems, the LMH6517SQ/NOPB provides designers with a versatile and high-fidelity solution for variable gain amplification needs.
