TLA2518IRTET

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).
