AD8331/AD8332/AD8334 Active Impedance Matching The LNA supports active impedance matching through an external shunt feedback resistor from Pin LON to Pin INH. The input resistance given in Equation 5, where A is the single- IN ended gain ...
Page 27
The primary purpose of input impedance matching is to improve the system transient response. With resistive termination, the input noise increases due to the thermal noise of the matching resistor and the increased contribution of the LNA input voltage noise ...
Page 28
AD8331/AD8332/AD8334 VGA Noise In a typical application, a VGA compresses a wide dynamic range input signal to within the input span of an ADC. While the input-referred noise of the LNA limits the minimum resolvable input signal, the output-referred noise, ...

Output Clamping Outputs are internally limited to a level of 4.5 V p-p differential when operating at a 2.5 V common-mode voltage. The postamp implements an optional output clamp engaged through a resistor from R to ground. Table 8 shows ...

AD8331/AD8332/AD8334 APPLICATIONS INFORMATION LNA—EXTERNAL COMPONENTS The LMD pin (connected to the bias circuitry) must be bypassed to ground and signal sourced to the INH pin, which is capacitively coupled using 2 0.1 μF capacitors (see Figure 81). The ...
Page 31
Gain Input The GAIN pin is common to both channels of the AD8332. The input impedance is nominally 10 MΩ, and a bypass capacitor from 100 recommended. Parallel connected devices can be driven by a ...
