1 Overview
Overview
The DRV600EVM evaluation module demonstrates the capabilities and performance of the DRV600RTJfrom Texas Instruments.
The DRV600 is a stereo line driver designed to allow the removal of the dc-blocking capacitors typicallyfound in an audio application, reducing overall component count and cost. The DRV600 is ideal forsingle-supply electronics where size and cost are critical design parameters.
The DRV600 is capable of driving 2V
RMS
into a 600 Ωload with a 3.3V supply. The DRV600 has a fixedgain of –1.5V/V and line outputs that have ±8kV electrostatic discharge (ESD) protection. The DRV600also has independent shutdown controls for the left and right audio channels.
This EVM is configured with two RCA phone input connectors and two RCA phone output connectors. Thepower supply is connected via a 2-pin, 2.54mm pin header. Table 1 summarizes the key parameters of thedevice.

DRV600EVM Performance
The DRV600EVM uses a 1 μF film capacitor for ac-coupling of the input signal. If a lower cost ceramiccapacitor such as an X7R is used, higher THD at low frequencies should be expected. Y5V capacitors willshow even higher THD performance and should not be used.
Figure 8. THD+N vs Frequency (600 Ωload) Using X7R Input Caps
The X7R capacitors raises the 20Hz THD from 0.02% to 0.1%—five times higher.

DRV600EVM Performance
Measurement bandwidth filter is set to 500kHz.
Figure 12. Frequency Response
Figure 13. Phase Response
The low frequency cutoff of 10Hz (–3dB) is determined by the input ac-coupling capacitor together with theinput impedance of the DRV600.
A 1 μF capacitor is used on the DRV600EVM. The input impedance of the DRV600 is 15k Ω. Thisimpedance gives a –3dB cutoff of 10Hz. This result corresponds with the frequency responsemeasurements above.
An RC filter is placed at the DRV600 to filter high-frequency noise. A 220 Ωresistor and a 1nF NPOcapacitor is used. This configuration gives a –3dB frequency of 720kHz.
No input signal is applied. The measurement results are presented both in a time domain and in afrequency domain. The resistor load is 600 Ωin both examples.
The power supply is applied, and then the shutdown signal is released. The shutdown signal is used totrigger the measuring system.

The DRV600 shows very low pop interference during the enable time; only two small, high-frequencyspikes can be seen.
No input signal is applied. The measurement results are presented both in a time domain and in afrequency domain.
The resistive load is 600 Ωin both examples.
Figure 15. Pop/Click (Disable)
During power-down, the click is even lower than during power-on (enable). A very small click is seen.

EVM WARNINGS AND RESTRICTIONS
It is important to operate this EVM within the input voltage range of 1.8 V to 4.5 V and the output voltage range of 2 Vrms.Exceeding the specified input range may cause unexpected operation and/or irreversible damage to the EVM. If there are questionsconcerning the input range, please contact a TI field representative prior to connecting the input power.Applying loads outside of the specified output range may result in unintended operation and/or possible permanent damage to the EVM.Please consult the EVM User's Guide prior to connecting any load to the EVM output. If there is uncertainty as to the load specification,please contact a TI field representative.During normal operation, some circuit components may have case temperatures greater than 85 °C. The EVM is designed to operateproperly with certain components above 85 °C as long as the input and output ranges are maintained. These components include but arenot limited to linear regulators, switching transistors, pass transistors, and current sense resistors. These types of devices can be identifiedusing the EVM schematic located in the EVM User's Guide. When placing measurement probes near these devices during operation,please be aware that these devices may be very warm to the touch.
