Page 3: Introduction
Evaluation Module Overview 4.1 Introduction The TAA3040EVM-K is an evaluation module (EVM) designed to demonstrate the performance and functionality of the TAA3040 family of devices. This family includes the devices shown in Table 4-1 with differences in performance and function noted. -
Page 4: Hardware Overview
The evaluation kit consists of the TAA3040EVB daughterboard and the AC-MB motherboard. The motherboard is used to provide power, control, and digital audio signals to the evaluation module. The daughterboard contains the TAA3040 device and its input connections. A detailed functional overview of the TAA3040EVB system is described in Section 5.1 AC-MB Settings... -
Page 5: Figure 5-2. Ac-Mb Usb Audio Setting
The AC-MB is detected by the OS as an audio device with the name TI USB Audio UAC2.0. Figure 5-2 shows the AC-MB audio setting for the USB mode of operation. Figure 5-2.

Page 6: Figure 5-3. Ac-Mb Optical Or Auxiliary Analog Audio Setting
This feature can be useful when a digital input DAC is connected to the AC-MB, providing an analog input for quick evaluation. In Auxiliary Analog Audio mode the audio serial interface format is fixed to a 24-bit, 48-kHz, I mode.

Page 10: Taa3040Evm-Pdk Hardware Settings
The different operation modes are highlighted in this section. The INxP and INxM pins of the TAA3040 can optionally connect to an onboard microphone for quick evaluation, and can be optionally configured to bypass the input decoupling capacitors for evaluating the functionality of the digital microphones or GPIOs. -
Page 11: Figure 5-8. Taa3040Evb Connection For Line Input Application
For the line input configuration (shown in Figure 5-8), the TAA3040 captures the audio signal provided through terminals J2 (IN1), J3 (IN2), J4 (IN3), and J5 (IN4). The input accepted in this mode is a differential, 2-VRMS, full-scale audio signal. If a single-ended source is used, the 1-VRMS signal is supported. -
Page 12: Figure 5-9. Taa3040Evb Connection For The Onboard Microphone Test
For the onboard microphone input configuration (shown in Figure 5-9), the TAA3040 records the audio captured from the microphones located on the bottom edge of the board. MICBIAS is used to power the onboard microphone, so header J14 must be shorted. There must not be any connections to J1 during onboard microphone use to preserve the performance of the microphone. -

Page 15: Figure 6-4. Audio Config Tab
Before changing any parameters, check the lower left corner of the PPC3 window, as shown in Figure 6-5, to verify that the EVM is connected. If no EVM is detected, the text will read TAA3040 offline. If the EVM is detected, a Connect button appears. Clicking this button connects the hardware. Figure 6-5. Hardware Connect When the hardware is connected, the Connect button changes to read Disconnect, and the device is ready to be configured. -
Page 16: Quick Start
Figure 7-2. MIC Bias Configuration The default state for the TAA3040 is standby mode and, with the exception of the channel digital volume, all device configurations must be done in standby mode. The TAA3040 does not provide a digital audio output in standby mode. -
