PGA460TPWR from Texas Instruments, in a TSSOP-16. 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 GND power_in Ground; absolute maximum ground voltage is -0.3 to 0.3 V and recommended -0.1 to 0.1 V.
2 INP input Positive transducer receive input; recommended operating range -0.1 to 0.9 V (abs max -0.3 to 2 V).
3 INN input Negative transducer receive input; recommended operating range -0.1 to 0.9 V (abs max -0.3 to 2 V).
4 GND power_in Ground; absolute maximum ground voltage is -0.3 to 0.3 V and recommended -0.1 to 0.1 V.
5 OUTA output Transducer driver output A (low-side driver), rated -0.3 to 30 V with 500 mA maximum sink current.
6 GNDP power_in Power ground for the output drivers; recommended -0.1 to 0.1 V.
7 OUTB output Transducer driver output B (low-side driver), rated -0.3 to 30 V with 500 mA maximum sink current.
8 IO bidirectional Time-command interface data input and output (open-drain with internal 10-kΩ pullup, also UART), rated -0.3 to 30 V.
9 TEST bidirectional Test output pin; its level at power-up selects 3.3 V (low) or 5 V (high) digital outputs, and it can output internal test-mux signals; -0.3 to 5.5 V.
10 TXD output USART interface transmit output, 3.3 V or 5 V CMOS level depending on the TEST pin level at power-up.
11 RXD input USART interface receive input; recommended -0.1 V to VIOREG (abs max -0.3 to 5.5 V).
12 SCLK input USART synchronous-mode clock input; recommended -0.1 V to VIOREG (abs max -0.3 to 5.5 V).
13 DECPL output Decoupling transistor gate drive output, rated -0.3 to 5.5 V.
14 IOREG power_out I/O buffer voltage regulator capacitor pin, rated -0.3 to 5.5 V.
15 VPWR power_in Power-supply voltage input; recommended 6 to 15 V for transformer topology and 6 to 28 V for direct drive (abs max 30 V).
16 AVDD power_out Analog voltage-regulator capacitor pin, rated -0.3 to 2 V.

Materials and finish

As the datasheet states them (page.json metadata.appearance; the 3D model's colours follow it).

Part Material Colour / plating Datasheet says Page
contacts copper • The analog drive pins can be high-current, high-voltage, or both and therefore the design limitation of the OUTA and OUTB pins is based on the copper trace profile. The driver pins are recommended t 111
