Single-Supply Operation  
As seen in Figure 5, eni is dominated by the intrinsic voltage  
noise (en) of the amplifier for equivalent source resistance  
below 121Ω. Between 121Ω and 5.11kΩ, eni is dominated by  
The CLC5801 can be operated with single power supply as  
shown in Figure 7. Both the input and output are capacitively  
coupled to set the DC operating point.  
the thermal noise (  
Above 5.11kΩ, eni is dominated by the amplifier’s current  
noise ( Rseq). The point at which the CLC5801’s volt-  
age noise and current noise contribute equally occurs for

gain of +20V/V giving a −3dB of 90MHz and driven from an  
Rseq = 25Ω, the CLC5801 produces a total equivalent input  
noise voltage (  
) of 26µVrms.

FIGURE 7. Single Supply Operation  
Low Noise Transimpedance Amplifier  
Figure 8 shows a transimpedance amplifier used to amplify  
the small signal from a Photodiode. Using a low noise ampli-  
fier such as the CLC5801 and proper design, ensures that  
the amplifier noise contribution is minimal. Here Rb can be  
used to compensate for the input bias current of the  
CLC5801. Generally, Rb is selected to be equal to Rf to can-  
cel the effect of Ib flowing in each of the Op Amp input  
terminals.  
DS101307-34  
FIGURE 5. Voltage Noise Density vs. Source  
Resistance  
If bias current cancellation is not a requirement, then Rf || Rg  
does not need to equal Rseq. In this case, according to Equa-  
tion (1), Rf || Rg should be as low as possible in order to mini-  
mize noise. Results similar to Equation (1) are obtained for  
the inverting configuration of Figure 2 if Rseq is replaced by  
Rb and Rg is replaced by Rg + Rs. With these substitutions,  
Equation (1) will yield eni referred to the non-inverting input.  
Referring eni to the inverting input is easily accomplished by  
multiplying eni by the ratio of non-inverting to inverting gains.  
Inverting Gains Less Than 10V/V  
The lag compensation of Figure 6 will achieve stability for  
lower gains. Placing the network between the two input ter-  
minals does not affect the closed-loop nor noise gain, but is  
best used for the inverting configuration because of its affect  
on the non-inverting input impedance.

FIGURE 8. Transimpedance Amplifier Configuration  
Figure 9 shows the equivalent noise analysis schematic for  
this circuit. The complete expression for the amplifier stage  
output rms noise is shown in Equation (3).
