MCP47CVB21-E

Microchip Tech · Digital To Analog Converters (DACs) · DFN-10-EP(3x3)

MCP47CVB21-E from Microchip Tech, in a DFN-10-EP(3x3). 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 VDD power_in Positive supply voltage pin, 2.7V to 5.5V for full specifications (1.8V to 2.7V reduced), with a 0.1 µF ceramic bypass capacitor recommended close to the pin.
2 A0 input I2C slave address bit 0 pin (Schmitt trigger input) that sets the lowest bit of the slave address.
3 VREF power_in Analog voltage reference input (buffered or unbuffered) when VREF is selected, or output when the internal band gap is the reference; it is disconnected when VDD is the reference.
4 VOUT output Buffered analog voltage output of the DAC, with about 1 Ω DC impedance in Normal mode and a 1 kΩ, 100 kΩ or open pull-down in Power-Down mode.
5 NC unconnected Not internally connected.
6 LAT/HVC input Schmitt-trigger latch pin that transfers the volatile DAC wiper and configuration register values to VOUT, also the high-voltage command pin for MTP writes (7.5V, at least 6.4 mA; voltages above 5.5V only during MTP programming).
7 VSS power_in Ground reference pin for all circuitry on the device.
8 A1 input I2C slave address bit 1 pin (Schmitt trigger input).
9 SCL input I2C serial clock input (Schmitt trigger); supports up to 3.4 MHz in High-Speed mode.
10 SDA bidirectional I2C serial data input/output pin (Schmitt trigger) with slope control on the output driver.
11 EP passive Exposed pad (from the footprint; not named in the datasheet pin table).
