TYPICAL APPLICATIO S
The LT6233 is applied as a transimpedance amplifier with
an I-to-V conversion gain of 10k
set by R1.The LT6233
is ideally suited to this application because of its low input
offset voltage andcurrent, and its low noise.This is be-
cause the 10k resistor has an inherent thermal noise of
13nV/
Hz or 1.3pA/
Hz at room temperature,while the
LT6233contributes only 2nV and 0.8pA /
Hz.So, with
respect to both voltage and current noises, the LT6233 is
actually quieter than the gain resistor.
The circuit uses an avalanche photodiode with the cathode
biased to approximately 200V.When light is incident on
the photodiode, it induces a current I
PD
which flowsinto
the amplifier circuit. The amplifier output falls negative to
maintain balance at its inputs. The transfer function is
therefore V
OUT
= –I
PD
10k. C1 ensures stability and good
settling characteristics.Output offset was measured
atbetter than 500
μ
V, so low in part because R2 serves to
cancel the DC effects of bias current.Output noise was
measured at below 1mV
P–P
on a 20MHz measurement
bandwidth, with C2 shunting R2’s thermal noise.As shown
in the scope photo, the rise time is 45ns, indicating a signal
bandwidth of 7.8MHz.
