LTC2642CMS-16#TRPBF
Analog Devices · Digital To Analog Converters (DAC) · MSOP-10
LTC2642CMS-16#TRPBF from Analog Devices, in a MSOP-10. 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 | REF | input | Reference voltage input; apply an external reference between 2V and VDD. |
| 2 | CS | input | Serial interface chip select/load input; when CS is low SCLK is enabled to shift in data on DIN, and when CS is taken high the 16-bit word is latched and the DAC is updated. |
| 3 | SCLK | input | Serial interface clock input, CMOS and TTL compatible. |
| 4 | DIN | input | Serial interface data input; data is transferred to the device on the rising edge of SCLK. |
| 5 | CLR | input | Asynchronous clear input; a logic low clears the DAC to midscale on the LTC2642. |
| 6 | VOUT | output | DAC output voltage; the unipolar output range is 0V to VREF. |
| 7 | INV | passive | Center tap of the internal scaling resistors; connect to an external amplifier's inverting input in bipolar mode. |
| 8 | RFB | passive | Feedback resistor; connect to an external amplifier's output in bipolar mode, giving a bipolar output range of -VREF to VREF. |
| 9 | VDD | power_in | Supply voltage, set between 2.7V and 5.5V. |
| 10 | GND | power_in | Circuit ground. |
