User's Guide SBAU159 – October 2009 DAC7716EVM DAC7716EVM This user's guide describes the characteristics, operation, and use of the DAC7716EVM. The evaluation module (EVM) is an evaluation board that allows for quick and easy evaluation of the DAC7716 .
EVM Overview www.ti.com Contents 1 EVM Overview ............................................................................................................... 2 2 Analog Interface ......................................................................
www.ti.com Analog Interface 2 Analog Interface For maximum flexibility, the DAC7716EVM can interface to multiple analog sources. Samtec part numbers SSW-110-22-F-D-VS-K and TSM-110-01-T-DV-P provide a 10-pin, dual-row, header at J1. This header provides access to the analog input and output pins of the DAC.
Digital Interface www.ti.com 3.1 Serial Data Interface Samtec part numbers SSW-110-22-F-D-VS-K and TSM-110-01-T-DV-P provide a 10-pin, dual-row, header/socket combination at J2. This header/socket provides access to the digital control and serial data pins from both J2A (top side) and J2B (bottom side) of the connector.
www.ti.com Power Supplies 4 Power Supplies Samtec part numbers SSW-105-22-F-D-VS-K and TSM-105-01-T-DV-P provide a 5-pin, dual-row, header/socket combination at J3. Table 3 lists the configuration details for J3. The voltage inputs to the DAC can be applied directly to the device.
EVM Operation www.ti.com Note that if an external reference voltage is input to J1.20, it will be filtered through a first-order, low-pass RC filter. To input your own reference signal without this filter, connect the reference signal directly to TP1 or TP2.
www.ti.com EVM Operation 6.3 Default Jumper Settings and Switch Positions Figure 2 shows the jumpers found on the EVM and the respective factory default conditions for each. Figure 2. DAC7716EVM Default Jumper Locations Jumper JP1 controls whether the LDAC signal is controlled by J2.
Schematics and Layout www.ti.com Switch S1 allows the user to pull down four control signals to ground. LDAC, Uni/Bip B, RST, and Uni/Bip A can be pulled low using the switch. By default, switch position S1.1 is open, causing LDAC to be connected to ground.
