Product details
Overview
DAC124S085EVM from Texas Instruments is an evaluation board designed to accelerate development with the DAC124S085 12-bit quad digital-to-analog converter in VSSOP-10 packaging, featuring rail-to-rail output, 4.096-V internal reference, and SPI-compatible serial interface - used for precision analog stimulus generation in test instrumentation and sensor calibration systems.
For engineers reviewing the DAC124S085EVM datasheet, DAC124S085EVM pinout, DAC124S085EVM application, or DAC124S085EVM equivalent, this BoosterPack provides rapid hardware-software co-validation of DAC124S085 performance across all four channels, supports MSP430F5529 LaunchPad integration, and enables real-time GUI-driven output code programming via USB virtual COM port.
Technical Context
The DAC124S085EVM implements a complete signal chain: LM4120IM5-4.1 voltage reference (4.096 V, ±0.5% initial accuracy) feeds the DAC124S085CIMM's VREFIN pin, while the board interfaces directly to MSP430 LaunchPad headers (JA, JB, JC, JD) for power, SPI clock (SCLK), data (DIN), synchronization (SYNC), and ground routing.
It supports full 12-bit resolution operation (0–4095 codes), delivers rail-to-rail output swing on all four independent channels (VOUTA–VOUTD), and uses passive decoupling (0.01 µF, 0.1 µF, 4.7 µF ceramics/tantalums) per TI layout best practices for low-noise analog performance.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Board Type | Evaluation module (BoosterPack) for DAC124S085 IC only - not a standalone product or production-ready subsystem. |
| Target Device | DAC124S085CIMM/NOPB - 12-bit, 4-channel, rail-to-rail output DAC in 10-pin VSSOP package with SPI interface. |
| Reference Voltage | 4.096 V from LM4120IM5-4.1 SOT-23 reference - enables full-scale output of 4.096 V with 1 mV/LSB step size. |
| Host Interface | MSP430F5529 LaunchPad via 10-pin headers (JA/JB/JC/JD) - provides 3.3 V logic, SPI signals, and GND; requires firmware upgrade. |
| Software Support | DAC12xSxxx GUI v1.x - enables channel selection (DB[15:12]), 12-bit code entry (DB[11:0]), and real-time write commands over USB CDC COM port. |
| Output Connectors | 5-pin header J1 (VA, VOUTA–VOUTD, GND) - provides direct access to all four analog outputs and reference voltage node. |

FAQ
What is the DAC124S085EVM used for?
The DAC124S085EVM is a Texas Instruments BoosterPack evaluation module specifically built to demonstrate and validate the DAC124S085 12-bit quad DAC. It enables engineers to rapidly prototype analog output circuits using the DAC124S085CIMM IC, verify SPI communication timing, characterize rail-to-rail output linearity, and integrate with MSP430F5529 LaunchPad hardware - all without custom PCB design.
Does the DAC124S085EVM include the DAC124S085 IC?
Yes, the DAC124S085EVM includes one DAC124S085CIMM/NOPB IC mounted in a 10-pin VSSOP package (U2). This is the exact production-grade device intended for end applications - not a sample or placeholder. The board also integrates the LM4120IM5-4.1 reference (U1) and all necessary passive components per TI's validated schematic and layout.
Which microcontroller platforms does the DAC124S085EVM support?
The DAC124S085EVM is designed exclusively for use with the MSP430F5529 LaunchPad (TI part number MSP-EXP430F5529LP). It connects via four 10-pin headers (JA, JB, JC, JD) and requires the DAC12xSxxx firmware preloaded onto the LaunchPad's MSP430F5529 MCU - which must be installed using TI's MSP430 USB Firmware Upgrade tool before first use.
Can the DAC124S085EVM operate without a computer?
No - the DAC124S085EVM has no onboard controller or standalone operation capability. It relies entirely on host PC communication via USB-connected MSP430 LaunchPad, running the DAC12xSxxx GUI software to send SPI commands. All configuration, code loading, and output updates are initiated and controlled from the PC-side GUI application.
Is the DAC124S085EVM FCC-certified?
Yes - the DAC124S085EVM is classified as a Class A digital device compliant with FCC Part 15 regulations. Its certification applies strictly to evaluation use in commercial environments; it is not certified for residential deployment or incorporation into finished products. Users must comply with TI's EVM terms regarding interference mitigation and operational restrictions.
