LXE1711-100 EVALUATION BOARD
USER GUIDE
LXE1711-100 Evaluation Board Quick Start Guide
The LXE1711-100 Evaluation Board is a fully functional mono class-D amplifier. Connection to a single power supply, one
speaker, and an audio source is all that is required to begin evaluating the amplifier. The amplifier will support continuous output
power levels up to >110W into 2 ohm load (<1% THD+N).
Board Setting
1. Power and Ground Connections: The terminal TB1 is for the power supply connection. Vcc is connected to the
positive polarity of the power supply or battery (+7V ~ +25V); the GND is connected to the negative polarity of the
power supply or battery. Please make sure your power supply polarity connection and supply voltage is correct
before you start to evaluate the board.
2. Speaker Connection: TB2 is speaker output. Connect speaker “+” and “-“ to “OUT+” and “OUT-“ of TB2. This
evaluation board is designed for standard 4 ohm speaker loads. For different impedance speakers, the output filter
values should be modified to optimize the output frequency response. Please see AudioMAX Design Resource
(AN-16) for LC filter values.
3. Audio Input Connections: P1 and J1 are the audio input connections. P1 supports differential audio inputs, and J1 is
for the single-ended audio inputs. When audio inputs are differential, the positive audio inputs are connected to IN+
pin, while the negative input is connected to IN- pin of the P1 terminal. P2 jumper is left open when using
differential input. When audio inputs are single-ended, the inputs audio source can either be connected to terminal
P1, or to J1. In this single-ended connection, jumpers P2 must be closed so that the IN- is connected to Ground.
4. SLEEP/MUTE Connections: P3 is the jumper selection for ON/OFF of the MUTE function, and P4 is the jumper for
ON/OFF of the SLEEP function. To enable the amplifier, both jumpers should be set to “OFF” (SLEEP is OFF,
default is left OPEN, and MUTE is OFF).
Audio Performance
1. 20Hz-20kHz Audio Bandwidth, less than ±1dB;
2. THD+N <0.06% Typical (1Wrms, 1kHz, 4 ohms);
3. Maximum Efficiency 85%-90%;
4. Output Power:
60W @4ohm, <1%THD+N; 80W @4ohm, 10%THD+N
110W @2ohm, <1%THD+N; 150W@2ohm, 10%THD+N;
5. PSRR: 70dB Typical ;
6. Differential Input To Minimize noise Effects;
