The 16-bit DAC82001 is a highly accurate, low-power, single-channel digital-to-analog converter (DAC) with an unbuffered voltage output.
The DAC82001 works with 3.3-V and 5-V supplies and offers linearity of 1‑LSB DNL and 2‑LSB INL. The high accuracy combined with a tiny package make the device an excellent choice for applications such as gain and offset calibration, voltage set point generation, and power-supply control. The DAC82001 incorporates a power-on-reset (POR) circuit. The POR circuit makes sure that the DAC output powers up at zero scale or midscale based on the status of RSTSEL pin, and remains at that scale until a valid code is written to the device. All internal registers are asynchronously reset after the RESET pin is pulled low.
The DAC82001 uses a versatile, three-wire serial peripheral interface (SPI) that operates at clock rates of up to 50 MHz.

PIN | TYPE | DESCRIPTION | |
---|---|---|---|
NAME | NO. | ||
AGND | 4 | Ground | Ground reference point for all circuitry on the device. |
NC | 9 | — | Do not connect |
RESET | 5 | Input | Asynchronous reset. Active low. If RESET is low, all DAC channels reset either to zero-scale (RSTSEL = AGND) or to midscale (RSTSEL = VDD). |
RSTSEL | 3 | Input | Reset select pin. DAC powers up to zero scale if RSTSEL = AGND. DAC powers up to midscale if RSTSEL = VDD. |
SCLK | 6 | Input | Serial interface clock of SPI. |
SDIN | 8 | Input | Serial interface data input of SPI. Data are clocked into the input shift register on each falling edge of the SCLK pin. |
SYNC | 7 | Input | Serial data enable of SPI. Active low. This input is the frame-synchronization signal for the serial data. When the signal goes low, the serial interface input shift register is enabled. |
VDD | 1 | Power | Analog supply voltage (2.7 V to 5.5 V) |
VOUT | 2 | Output | Analog output voltage from DAC |
VREF | 10 | Input | This pin is the external reference input to the device. |
