MCP3426A6-E
Microchip Tech · Analog To Digital Converters (ADCs) · MSOP-8
MCP3426A6-E from Microchip Tech, in a MSOP-8. 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 | CH1+ | input | Positive differential analog input of channel 1, which must stay within VSS-0.3V to VDD+0.3V to avoid ESD diode leakage. |
| 2 | CH1- | input | Negative differential analog input of channel 1, which can be tied to VSS for single-ended operation and must stay within VSS-0.3V to VDD+0.3V. |
| 3 | VDD | power_in | Positive supply pin that must be maintained at 2.7V to 5.5V for specified operation, with about 0.1 µF ceramic plus 10 µF tantalum bypass to ground recommended. |
| 4 | SDA | bidirectional | Open-drain N-channel I2C serial data pin that needs a pull-up to VDD, typically 5 kΩ to 10 kΩ for standard and fast modes and less than 1 kΩ for high-speed mode (3.4 MHz). |
| 5 | SCL | input | I2C serial clock input that accepts only external clocks from the master and needs a pull-up to VDD, typically 5 kΩ to 10 kΩ for standard and fast modes and less than 1 kΩ for high-speed mode (3.4 MHz). |
| 6 | VSS | power_in | Ground pin and current return path of the device, which must be connected to a low-impedance ground plane. |
| 7 | CH2+ | input | Positive differential analog input of channel 2, which must stay within VSS-0.3V to VDD+0.3V to avoid ESD diode leakage. |
| 8 | CH2- | input | Negative differential analog input of channel 2, which can be tied to VSS for single-ended operation and must stay within VSS-0.3V to VDD+0.3V. |
