MCP6S28T-I

Microchip Tech · Programmable/Variable Gain Amplifiers (PGAs/VGAs) · SOIC-16

MCP6S28T-I from Microchip Tech, in a SOIC-16. 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 VOUT output Analog output, a low-impedance voltage source whose value is set by the selected gain, selected input channel and the voltage at VREF; short-circuit current typically ±30 mA.
2 CH0 input Analog input channel 0, a high-impedance CMOS input with low bias current that the internal MUX can select for amplification.
3 CH1 input Analog input channel 1, a high-impedance CMOS input with low bias current that the internal MUX can select for amplification.
4 CH2 input Analog input channel 2, a high-impedance CMOS input with low bias current that the internal MUX can select for amplification.
5 CH3 input Analog input channel 3, a high-impedance CMOS input with low bias current that the internal MUX can select for amplification.
6 CH4 input Analog input channel 4, a high-impedance CMOS input with low bias current that the internal MUX can select for amplification.
7 CH5 input Analog input channel 5, a high-impedance CMOS input with low bias current that the internal MUX can select for amplification.
8 CH6 input Analog input channel 6, a high-impedance CMOS input with low bias current that the internal MUX can select for amplification.
9 CH7 input Analog input channel 7, a high-impedance CMOS input with low bias current that the internal MUX can select for amplification.
10 VREF power_in External reference pin that should be at a voltage between VSS and VDD and shifts the output voltage.
11 VSS power_in Negative power supply pin, normally connected to ground in single-supply use, with VDD 2.5V to 5.5V above it.
12 CS input SPI chip select, a Schmitt-triggered CMOS logic input.
13 SI input SPI serial data input, a Schmitt-triggered CMOS logic input.
14 SO output SPI serial data output, a CMOS push-pull output that never goes High-Z and is forced low when CS goes high, supporting daisy chaining.
15 SCK input SPI clock input, a Schmitt-triggered CMOS logic input.
16 VDD power_in Positive power supply pin, 2.5V to 5.5V above VSS, needing a local 0.1 µF bypass capacitor.
