Mailing Address: Texas Instruments Post Office Box 655303 Dallas, Texas 75265 Copyright 2003, Texas Instruments Incorporated EVM WARNINGS AND RESTRICTIONS It is important to operate this EVM within the input voltage range of 15 V. Exceeding the specified input range may cause unexpected operation and/or irreversible damage to the EVM. If there are questions concerning 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 60°C. The EVM is designed to operate properly with certain components above 60°C as long as the input and output ranges are maintained. These components include but are not limited to linear regulators, switching transistors, pass transistors, and current sense resistors. These types of devices can be identified using 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.

Figure 2−1. Block Diagram P1 / J1 Signal Conditioning TLC3578 TLC3574 TLC3548 TLC3544 TLC2578 TLC2574 The channels are arranged to comply with the EVM standard developed for data converters. This standard defines eight channels of analog I/O on each EVM module. 2.2 Signal Conditioning The facility exists for the signal connected to channel 0 to be conditioned via an operational amplifier. The amplifier present on the EVM operates from a dual power supply and is configured with a gain of +1. If signal conditioning is not required, it can easily be bypassed via a shorting bar. 2.3 Single Supply Operation Should the user wish to operate the amplifier from a single suply rail, this is also possible by simply removing the dual supply amplifier and replacing it with a suitable single supply alternative, for example the OPA353. The suggested procedure is detailed below: - Carefully desolder amplifier, U1 - Replace with a suitable single-supply alternative, for example TI part num- ber OPA353UA - Install appropriate resistor at R9 - Install appropriate capacitor at C11 - Install shorting bar at W1 2-2 Physical Pinout Description 2.4 Physical Pinout Description Samtec part numbers SSW-110-22-F-D-VS-K and TSM-110-01-T-DV-P provide a convenient 10-pin dual row header/socket combination at P1.

It is very important, therefore, that the reference be stable, accurate and low drift. The ADC reference pin presents a dynamic capacitive load to the amplifier. The voltage supplied to the ADC must be capable of driving this dynamic load properly, ensuring that the reference remain stable regardless of load. The bipolar and unipolar devices are specified to use a different voltage for the reference pin. Table 2−2.

There are two ways to provide these voltages. - Hook-up the test points on the EVM. The test points are clearly labeled +Vdd (3.3 V to 5 V), +5VA, +Vs (up to 18 V depending upon the amplifiers) and –Vs (up to –18 V depending upon the amplifiers). - Use the power connector P5/J5 and derive the voltages elsewhere.

Hardware and software offerings from TI help you easily get from concept to hardware and software prototype. Topic 5.1 Page Additional Hardware Options . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 5-2 Getting the Most From Your EVM 5-1 Additional Hardware Options 5.1 Additional Hardware Options In general there are three hardware directions that the user can take with the EVM. 5.1.1 Stand-Alone EVM The EVM can be used on its own. Using the EVM in this manner obliges the user to provide a custom digital interface between the EVM and a host system. Users are entirely responsible for ensuring proper timing requirements are met in addition to providing any glue logic necessary. Users must also provide the necessary analog interface and supply power to the EVM. 5.1.2 DSP Interface Depending upon the DSP that the user chooses, there are a number of TI DSKs available. DSKs are DSP Starter Kits, and provide users with a DSP starter system. They contain all the necessary hardware and software to quickly begin prototype construction. For example, the TMS320C6711 DSP starter kit includes the DSK hardware, a parallel port cable to connect to a PC, a 5-V universal power supply, and a Code Composer Studio CD-ROM containing all the necessary software. Each family of DSKs provides different physical interface options. These interface options enable address, data, and control signals to be decoded and used by mezzanine-level cards (such as EVMs). To connect this EVM to any DSK requires selection of the correct interface card. Generally the procedure is outlined below. - Select the DSP you wish to use. - Select the appropriate DSK. - Select the suitable interface card. As an example, assume that the user wishes to use the TLC3578 EVM with the TMS320C6711 DSP, the steps that should be taken are shown below following a side-elevation of the boards required. 5-2 Additional Hardware Options Figure 5−1.
