**Analog Devices** · Analog To Digital Converters (ADC) · SSOP-16-150mil

LTC1867CGN#PBF from Analog Devices, in a SSOP-16-150mil. 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 | CH0 | input | Analog input channel 0; analog inputs must be noise-free and referenced to GND, absolute range −0.3V to VDD+0.3V. |
| 2 | CH1 | input | Analog input channel 1; analog inputs must be noise-free and referenced to GND, absolute range −0.3V to VDD+0.3V. |
| 3 | CH2 | input | Analog input channel 2; analog inputs must be noise-free and referenced to GND, absolute range −0.3V to VDD+0.3V. |
| 4 | CH3 | input | Analog input channel 3; analog inputs must be noise-free and referenced to GND, absolute range −0.3V to VDD+0.3V. |
| 5 | CH4 | input | Analog input channel 4; analog inputs must be noise-free and referenced to GND, absolute range −0.3V to VDD+0.3V. |
| 6 | CH5 | input | Analog input channel 5; analog inputs must be noise-free and referenced to GND, absolute range −0.3V to VDD+0.3V. |
| 7 | CH6 | input | Analog input channel 6; analog inputs must be noise-free and referenced to GND, absolute range −0.3V to VDD+0.3V. |
| 8 | CH7/COM | input | Analog input channel 7, either a single channel or the common negative input for the other channels. |
| 9 | REFCOMP | output | Reference buffer output (nominal 4.096V), to be bypassed to GND with a 10µF tantalum in parallel with a 0.1µF ceramic; tie VREF to GND to overdrive it. |
| 10 | VREF | power_in | 2.5V reference output that can also be used as an external reference buffer input for better accuracy and drift; bypass to GND with a 2.2µF tantalum in parallel with a 0.1µF ceramic. |
| 11 | CS/CONV | input | Dual-function input that starts a conversion on the ADC and frames the serial data transfer; digital input range −0.3V to 10V. |
| 12 | SCK | input | Shift clock that synchronizes the serial data transfer; fSCK max 40MHz, digital input range −0.3V to 10V. |
| 13 | SDO | output | Digital data output on which the A/D conversion result is shifted out, straight binary in unipolar mode and two's complement in bipolar mode; Hi-Z when CS/CONV is high. |
| 14 | SDI | input | Digital data input into which the A/D configuration word is shifted; digital input range −0.3V to 10V. |
| 15 | GND | power_in | Analog and digital ground. |
| 16 | VDD | power_in | Analog and digital power supply, 4.75V to 5.25V, bypassed to GND with a 10µF tantalum in parallel with a 0.1µF ceramic. |
