Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.++## Pinout++| Pin | Name | Type | Function |+|---|---|---|---|+| 1 | NC | unconnected | No internal connection; leave this pin unconnected. |+| 2 | ALARM | output | Open-drain alarm output that requires an external 10 kΩ pullup and goes low when an alarm condition (open circuit, over temperature, timeout, and so on) is detected. |+| 3 | GND | power_in | Ground reference point for all digital circuitry of the device. |+| 4 | GND | power_in | Ground reference point for all digital circuitry of the device. |+| 5 | CLR | input | Active-high clear input; a logic high on this pin puts the part into the CLEAR state. |+| 6 | LATCH | input | Load DAC registers input; a rising edge loads the input shift register data into the DAC data and control registers and updates the DAC output. |+| 7 | SCLK | input | SPI serial clock input supporting data transfer rates up to 30 MHz; Schmitt-trigger logic input. |+| 8 | DIN | input | Serial data input; data are clocked into the 24-bit input shift register on the rising edge of SCLK; Schmitt-trigger logic input. |+| 9 | SDO | output | Serial data output; data are valid on the rising edge of SCLK. |+| 10 | NC | unconnected | No connection; leave this pin unconnected. |+| 11 | NC | unconnected | No connection; leave this pin unconnected. |+| 12 | GND | power_in | Ground reference point for all analog circuitry of the device. |+| 13 | GND | power_in | Ground reference point for all analog circuitry of the device. |+| 14 | GND | power_in | Ground reference point for all analog circuitry of the device. |+| 15 | GND | power_in | Ground reference point for all analog circuitry of the device. |+| 16 | ISET-R | input | Connection pin for an external precision resistor (15 kΩ). |+| 17 | REFOUT | output | Internal reference output; connects to REFIN when the internal reference is used. |+| 18 | REFIN | input | Reference input pin; the recommended reference input voltage is 4.95 V to 5.05 V. |+| 19 | NC | unconnected | No connection; leave this pin unconnected. |+| 20 | NC | unconnected | No connection; leave this pin unconnected. |+| 21 | NC | unconnected | No connection; leave this pin unconnected. |+| 22 | NC | unconnected | No connection; leave this pin unconnected. |+| 23 | DVDD-EN | input | Internal power-supply enable; connect to GND to disable the internal supply (an external supply must then be applied to DVDD), or leave unconnected to enable it. |+| 24 | HART-IN | input | Input pin for HART modulation superimposed on the current output. |+| 25 | R3-SENSE | output | Output-current monitor; the voltage between R3-SENSE and BOOST is directly proportional to the output current. |+| 26 | IOUT | output | Current output pin; loop compliance is AVDD - 2 V at 24 mA. |+| 27 | BOOST | output | Boost pin for optional external transistor connection. |+| 28 | CAP1 | input | Connection for an optional output filtering capacitor. |+| 29 | CAP2 | input | Connection for an optional output filtering capacitor. |+| 30 | NC | unconnected | No connection; leave this pin unconnected. |+| 31 | NC | unconnected | No connection; leave this pin unconnected. |+| 32 | NC | unconnected | No connection; leave this pin unconnected. |+| 33 | NC | unconnected | No connection; leave this pin unconnected. |+| 34 | NC | unconnected | No connection; leave this pin unconnected. |+| 35 | NC | unconnected | No connection; leave this pin unconnected. |+| 36 | AVDD | power_in | Positive analog power supply; AVDD is specified at 10 V to 36 V. |+| 37 | GND | power_in | Ground reference point for all analog circuitry of the device. |+| 38 | NC | unconnected | No connection; leave this pin unconnected. |+| 39 | DVDD | power_in | Digital power supply that can act as an input or output depending on DVDD-EN; specified at 2.7 V to 5.5 V. |+| 40 | NC | unconnected | No connection; leave this pin unconnected. |+| 41 | Thermal Pad | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Texas Instruments |+| Package | VQFN-40-EP(6x6) |+| Category | Data Acquisition |+| Pins | 41 |++## CAD (KiCad official)++- Symbol: `DAC7750IRHAR`+- Footprint: `Package_DFN_QFN:QFN-40-1EP_6x6mm_P0.5mm_EP4.6x4.6mm`+- 3D model: VQFN-40-EP(6x6) (KiCad packages3D, STEP)+- 3D model files: `dac7750irhar-etched.step` / `dac7750irhar-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `dac7750irhar.step` / `dac7750irhar.glb` are the bare package body.++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [Texas Instruments datasheet](https://www.ti.com/cn/lit/gpn/dac7750) (64 pp, sha256 `ffe9891aabc1a855`, retrieved 2026-10-08, tier: lcsc)+- **Datasheet language:** Chinese.
