Specifications of MAX4338EVKIT

• Operating Supply Voltage: 3 V or 5 V

The MAX4338 EV kit has active-low shutdowns and
uses pullup resistors (R9 and R10) to activate these
shutdowns. Any shutdown current measurements
should take into account the current being drawn
through R9 and R10, as well as the current drawn
through the bias resistors R3 and R4. This current can
be calculated using the following equations (assumes
both shutdowns are active):
The maximum shutdown current of the MAX4338 is
0.5µA.

MAX4338 Evaluation Kit
Jumpers JU4 and JU5 removes the output DC-blocking
capacitors (C9 and C10) from the circuit. This allows
the user to drive a pure resistive load if desired.
Inserting JU4 or JU5 produces an output on the corre-
sponding channel with a DC component equal to
midrail (V
frequency of 30Hz (see Table 2 for shunt positions).
The MAX4338 EV kit also provides pads for the user to
solder up to two through-hole components per channel
onto the PC board (R7, C2 and R8, C4). This allows the
user access to test the op amps capacitive- and resis-
tive-load driving capabilities, without having to access
the output of the op amp through the headphone jack.
