LTC2642ACMS-16#PBF

Analog Devices · Digital To Analog Converters (DAC) · MSOP-10

LTC2642ACMS-16#PBF 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 shifts data in on DIN, and when CS goes high the 16-bit word is latched and the DAC is updated.
3 SCLK input Serial interface clock input, CMOS and TTL compatible; data on DIN is transferred on the rising edge of SCLK.
4 DIN input Serial interface data input; data is applied to DIN for transfer to the device at 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 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.
