DAC102S085 Datasheet – 10-Bit Micro Power Dual DAC
10-Bit Micro Power DUAL Digital-to-Analog Converter
DAC102S085 overview
The DAC102S085 is a 10-Bit Micro Power DUAL Digital-to-Analog Converter made by Texas Instruments, supplied in these packages: VSSOP, WSON 10 Pin Type. The absolute maximum ratings table on this page lists the 6 limits from the manufacturer's datasheet that must not be exceeded. This page brings together the DAC102S085 pinout and maximum ratings, with the full datasheet PDF to preview below or download.
The DAC102S085 is a full-featured, general-purpose DUAL 10-bit voltage-output digital-to-analog converter (DAC) that can operate from a single 2.7-V to 5.5-V supply and consumes 0.6 mW at 3 V and 1.6 mW at 5 V. The DAC102S085 is packaged in 10-pin WSON and VSSOP packages. The 10-pin WSON package makes the DAC102S085 the smallest DUAL DAC in its class. The on-chip output amplifier allows rail-to- rail output swing and the three wire serial interface operates at clock rates up to 40 MHz over the entire supply voltage range. Competitive devices are limited to 25-MHz clock rates at supply voltages in the 2.7-V to 3.6-V range. The serial interface is compatible with standard SPI™, QSPI, MICROWIRE and DSP interfaces. The reference for the DAC102S085 serves both channels and can vary in voltage between 1 V and VA, providing the widest possible output dynamic range. The DAC102S085 has a 16-bit input shift register that controls the outputs to be updated, the mode of operation, the power-down condition, and the binary input data. Both outputs can be updated simultaneously or individually depending on the setting of the two mode of operation bits

DAC102S085 pinout
| Pin | Name | Description |
|---|---|---|
| 1 | VA | Power supply input. Must be decoupled to GND. |
| 2 | VOUTA | Channel A Analog Output Voltage. |
| 3 | VOUTB | Channel B Analog Output Voltage. |
| 4, 5 | NC | Not Connected |
| 6 | GND | Ground reference for all on-chip circuitry. |
| 7 | VREFIN | Unbuffered reference voltage shared by all channels. Must be decoupled to GND. |
| 8 | DIN | Serial Data Input. Data is clocked into the 16-bit shift register on the falling edges of SCLK after the fall of SYNC. |
| 9 | SYNC | Frame synchronization input for the data input. When this pin goes low, it enables the input shift register and data is transferred on the falling edges of SCLK. The DAC is updated on the 16th clock cycle unless SYNC is brought high before the 16th clock, in which case the rising edge of SYNC acts a |
| 10 | SCLK | Serial Clock Input. Data is clocked into the input shift register on the falling edges of this pin. |
| 11 | PAD(1) | Exposed die attach pad can be connected to ground or left floating. Soldering the pad to the PCB offers optimal thermal performance and enhances package self-alignment during reflow. |
