The MAX4336 EV kit is fully assembled and tested.
Follow the steps below to verify board operation. Do
not turn on the power supply until all connections
are completed:
1) Plug the headphones into the 3.5mm headphone
2) Ensure that the audio source is turned off.
3) Connect the disabled audio source using the single
4) Ensure that the shunts are in the following positions:
5) Connect the 2.7V to 5V DC power supply to the
6) Turn on the 2.7V to 5V DC power supply.
7) Turn on the audio source.
The MAX4336 EV kit is a mono, single-supply audio
amplifier designed to be directly connected to any
mono audio source, such as a CD player. The input
impedance is 22.1kΩ. The -3dB corner frequencies are
approximately 30Hz and 34kHz with a 32Ω load. The
MAX4336 EV kit has a fixed gain of approximately 2.1.
An input signal of 700mV
produces a full-range output with a 32Ω load. An input
signal of 400mV
a full-range output with a 32Ω load.

The MAX4336 EV kit provides a SHDN pin to disable
the output. Table 1 lists the options available for shut-
down control jumper JU1. An external controller can be
used by removing the shunt on JU1 completely and
connecting the external controller to the pad labeled
SHDN. SHDN is a TTL/CMOS logic-level input (see
Table 1 for shunt positions).
The MAX4336 EV kit has an active-low shutdown and
uses a pullup resistor (R5) to activate this shutdown.
Any shutdown current measurements should take into
account the current being drawn through R5, as well as
the current drawn through the bias resistors R3 and R4.
This current can be calculated using the following
equation:
The maximum shutdown current of the MAX4336 is
0.5µA.
Jumper JU2 removes the output DC-blocking capacitor
(C5) from the circuit. Inserting JU2 produces an output
with a DC component equal to midrail (V
changes the -3dB highpass corner frequency of 30Hz
(see Table 2 for shunt positions).
