Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | CH1+ | input | Positive differential analog input of channel 1; input pins 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; input pins must stay within VSS-0.3V to VDD+0.3V. |
| 3 | CH2+ | input | Positive differential analog input of channel 2; input pins must stay within VSS-0.3V to VDD+0.3V to avoid ESD diode leakage. |
| 4 | CH2- | input | Negative differential analog input of channel 2, which can be tied to VSS for single-ended operation; input pins must stay within VSS-0.3V to VDD+0.3V. |
| 5 | VSS | power_in | Ground pin and current return path of the device, which must be connected to a ground plane through a low impedance connection. |
| 6 | VDD | power_in | Positive supply pin, which must be maintained in the 2.7V to 5.5V range for specified operation and bypassed with about 0.1 µF ceramic plus 10 µF tantalum capacitors. |
| 7 | SDA | bidirectional | Open-drain N-channel I2C serial data pin that needs a pull-up resistor of 5 kΩ to 10 kΩ for standard and fast modes, or less than 1 kΩ for high speed mode (3.4 MHz). |
| 8 | SCL | input | Open-drain N-channel I2C serial clock pin that accepts only external clocks from the master and needs a pull-up resistor from VDD. |
| 9 | Adr0 | input | I2C address selection pin that is connected to VDD, VSS or left floating to select one of eight available addresses together with Adr1. |
| 10 | Adr1 | input | I2C address selection pin that is connected to VDD, VSS or left floating to select one of eight available addresses together with Adr0. |
| 11 | CH3+ | input | Positive differential analog input of channel 3; input pins must stay within VSS-0.3V to VDD+0.3V to avoid ESD diode leakage. |
| 12 | CH3- | input | Negative differential analog input of channel 3, which can be tied to VSS for single-ended operation; input pins must stay within VSS-0.3V to VDD+0.3V. |
| 13 | CH4+ | input | Positive differential analog input of channel 4; input pins must stay within VSS-0.3V to VDD+0.3V to avoid ESD diode leakage. |
| 14 | CH4- | input | Negative differential analog input of channel 4, which can be tied to VSS for single-ended operation; input pins must stay within VSS-0.3V to VDD+0.3V. |
