Output impedance is very low, with EQ stage open-loop and closed-loop gain being the same.
This allows for very low output impedance and very fast transient response, key performance requirements for today's demanding industrial, telecom and high-end consumer applications.
The output impedance of the driver changes depending on the drive strength--higher impedance for Class I (typically 35 [ohm]) and lower impedance for Class II (typically 17 [ohm]).
Input impedance is 47 kOhm + 120 pf, output impedance is 500 ohm, and gain is 40 dB@ 1kHz.
For example, the optional advanced features package includes a built-in oscilloscope function for measurement and display of: power, voltage, current, output impedance, output cable impedance and output cable voltage drop.
6V/V gain using a specific external build out resistor and a cross-coupled feedback, providing active output impedance with reduced losses.
Building on extensive experience in powering processors, ASICs, FPGAs - the new paper based on empirical studies powering DDR3 memory applications, demonstrates how real-time adaptive digital control can be used to greatly improve system stability, transient response and voltage regulator output impedance stability.
All four new GaN transistors can withstand output impedance (VSWR) mismatches up to 10:1 without functional damage and are optimized for operation at high drain bias conditions, reducing system cost and thermal management overhead.
High performance, low noise: The LM3290 and LM3291 provide high efficiency, low noise, low output impedance and low output ripple voltage at high LTE bandwidths (LTE10 and 20).
In addition, the new device offers a high level of programmability including programmable Dynamic VID slew rates, VID Offset (VDD output only), output impedance (VDD output only) and dynamic OC for IDD spike.
The higher voltage MOSFET also gives a higher output impedance, which is easier to match to 50 ohm load.
The low equivalent series resistance (ESR) of these capacitors ensures low output impedance at high frequencies.
