TLC0831CDR from Texas Instruments, in a SOIC-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 | CS | input | Active-low chip select: a conversion starts when CS goes low, CS must remain low for the complete conversion, and returning CS high clears the internal registers and puts DO in the high-impedance state. |
| 2 | IN+ | input | Positive analog input, compared against IN- in differential mode or against GND in single-ended mode; the output is all zeros when IN+ is below IN-, and on-chip diodes conduct when the input is one diode drop above VCC. |
| 3 | IN- | input | Negative analog input for differential operation, or tied to GND for single-ended operation; the output code is 0000 0000 when IN- is more positive than IN+. |
| 4 | GND | power_in | Network ground terminal to which all voltage values, except differential voltages, are referenced. |
| 5 | REF | input | Voltage reference input, typically set equal to the maximum analog input value (normally VCC for ratiometric operation), with input resistance of 1.3 kΩ min, 2.4 kΩ typ and 5.9 kΩ max. |
| 6 | DO | tri_state | Serial data output that delivers the conversion result MSB first, one bit per clock after the multiplexer-settling clock period, and is high impedance when CS is high. |
| 7 | CLK | input | Serial clock input with a recommended frequency of 10 kHz to 600 kHz and a 40% to 60% duty cycle, where the minimum pulse width is 1 µs if the duty cycle is exceeded. |
| 8 | VCC | power_in | Positive supply, recommended 4.5 V to 5.5 V (5 V nominal) with a 6.5 V absolute maximum; a 0- to 5-V input range requires a minimum VCC of 4.95 V. |
