TLA2518IRTER

Texas Instruments · Analog To Digital Converters (ADC) · WQFN-16-EP(3x3)

TLA2518IRTER 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 Analog input channel 2 with 0 to AVDD V range or configurable as digital input/output.
2 AIN3/GPIO3 bidirectional Analog input channel 3 with 0 to AVDD V range or configurable as digital input/output.
3 AIN4/GPIO4 bidirectional Analog input channel 4 with 0 to AVDD V range or configurable as digital input/output.
4 AIN5/GPIO5 bidirectional Analog input channel 5 with 0 to AVDD V range or configurable as digital input/output.
5 AIN6/GPIO6 bidirectional Analog input channel 6 with 0 to AVDD V range or configurable as digital input/output.
6 AIN7/GPIO7 bidirectional Analog input channel 7 with 0 to AVDD V range or configurable as digital input/output.
7 AVDD power_in Analog supply voltage input 2.35 to 5.5 V; also used as ADC reference voltage.
8 DECAP power_in Decoupling capacitor connection for internal power supply; requires 0.1 to 1 µF ceramic capacitor.
9 GND power_in Ground reference for analog and digital signals.
10 DVDD power_in Digital supply voltage input 1.65 to 5.5 V for SPI interface and GPIO circuits.
11 CS input Chip-select active-low digital input; device controls data bus when CS low and conversion starts on CS rising edge.
12 SDO output Serial data output MSB first; goes high-impedance when CS is high.
13 SCLK input Serial clock digital input for SPI interface supporting maximum 60 MHz frequency.
14 SDI input Serial data input digital signal for SPI interface with 1.5 ns setup and 2 ns hold time.
15 AIN0/GPIO0 bidirectional Analog input channel 0 with 0 to AVDD V range or configurable as digital input/output.
16 AIN1/GPIO1 bidirectional Analog input channel 1 with 0 to AVDD V range or configurable as digital input/output.
17 EP passive Exposed pad (from the footprint; not named in the datasheet pin table).
