Texas Instruments · Analog To Digital Converters (ADC) · WQFN-16-EP(3x3)
TLA2518IRTET from Texas Instruments, in a WQFN-16-EP(3x3). 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 | AIN2/GPIO2 | bidirectional | Channel 2; can be configured as either an analog input (default), digital input, or digital output. |
| 2 | AIN3/GPIO3 | bidirectional | Channel 3; can be configured as either an analog input (default), digital input, or digital output. |
| 3 | AIN4/GPIO4 | bidirectional | Channel 4; can be configured as either an analog input (default), digital input, or digital output. |
| 4 | AIN5/GPIO5 | bidirectional | Channel 5; can be configured as either an analog input (default), digital input, or digital output. |
| 5 | AIN6/GPIO6 | bidirectional | Channel 6; can be configured as either an analog input (default), digital input, or digital output. |
| 6 | AIN7/GPIO7 | bidirectional | Channel 7; can be configured as either an analog input (default), digital input, or digital output. |
| 7 | AVDD | power_in | Analog supply input, also used as the reference voltage to the ADC; connect a 1-µF decoupling capacitor to GND. |
| 8 | DECAP | passive | Connect a decoupling capacitor to this pin for the internal power supply. |
| 9 | GND | power_in | Ground for the power supply; all analog and digital signals are referred to this pin voltage. |
| 10 | DVDD | power_in | Digital I/O supply voltage; connect a 1-µF decoupling capacitor to GND. |
| 11 | CS | input | Chip-select input pin; active low; the device takes control of the data bus when CS is low; the device starts converting the active input channel on the rising edge of CS; SDO goes hi-Z when CS is high. |
| 12 | SDO | tri_state | Serial data out for the device; goes high impedance when CS is high. |
| 13 | SCLK | input | Serial clock for the SPI interface. |
| 14 | SDI | input | Serial data in for the device. |
| 15 | AIN0/GPIO0 | bidirectional | Channel 0; can be configured as either an analog input (default), digital input, or digital output. |
| 16 | AIN1/GPIO1 | bidirectional | Channel 1; can be configured as either an analog input (default), digital input, or digital output. |
| 17 | Thermal pad | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
