Functional Diagrams
Detailed Description
The MAX4007/MAX4008 are versatile current monitors
intended for monitoring DC photodiode current in fiber
applications (see Functional Diagram). The MAX4007
output is a current that is exactly one-tenth the refer-
ence current. The MAX4008 outputs a voltage that is
proportional to the reference current with a transimped-
ance gain of 1V/mA achieved by a factory-trimmed,
internal 10k?resistor.
Both current devices have six decades of dynamic
range and monitor reference current ranging from
250nA to 2.5mA, the nominal operating range, with bet-
ter than 5% accuracy across the entire reference cur-
rent, bias voltage, and temperature ranges. The
corresponding monitor outputs produce 25nA to
0.25mA (MAX4007) and 0.25mV to 2.5V (MAX4008).
When the reference currents are extended to the
broader range of 10nA to 10mA, an accuracy of less
than 10% is maintained. Internal current limiting (20mA,
