Applications Information
1-Cell and 2-Cell Circuit
See Figure 3 for an illustration of how to power the
MAX5510/MAX5511 with either one lithium-ion battery
or two alkaline batteries. The low current consumption
of the devices makes the MAX5510/MAX5511 ideal for
battery-powered applications.
Programmable Current Source
See the circuit in Figure 4 for an illustration of how to
configure the MAX5510 as a programmable current
source for driving an LED. The MAX5510 drives a stan-
dard NPN transistor to program the current source. The
current source (ILED) is defined in the equation in
Figure 4.
Voltage Biasing a Current-Output
Transducer
See the circuit in Figure 5 for an illustration of how to con-
figure the MAX5510 to bias a current-output transducer.
In Figure 5, the output voltage of the MAX5510 is a func-
tion of the voltage drop across the transducer added to
the voltage drop across the feedback resistor R.
Self-Biased Two-Electrode
Potentiostat Application
See the circuit in Figure 6 for an illustration of how to
use the MAX5511 to bias a two-electrode potentiostat
on the input of an ADC.
