AD7993BRUZ-1 from Analog Devices, 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	AGND	power_in	Analog ground reference for all circuitry on the AD7993/AD7994; all analog input signals should be referred to this AGND voltage.
2	AGND	power_in	Analog ground reference for all circuitry on the AD7993/AD7994; all analog input signals should be referred to this AGND voltage.
3	AGND	power_in	Analog ground reference for all circuitry on the AD7993/AD7994; all analog input signals should be referred to this AGND voltage.
4	AGND	power_in	Analog ground reference for all circuitry on the AD7993/AD7994; all analog input signals should be referred to this AGND voltage.
5	VDD	power_in	Power supply input, with a VDD range of 2.7 V to 5.5 V.
6	REFIN	input	Voltage reference input for the external reference, range 1.2 V to VDD, with 0.1 µF and 1 µF capacitors placed between REFIN and AGND.
7	VIN1	input	Analog Input 1, single-ended channel with an input range of 0 V to REFIN.
8	VIN3	input	Analog Input 3, single-ended channel with an input range of 0 V to REFIN.
9	VIN4	input	Analog Input 4, single-ended channel with an input range of 0 V to REFIN.
10	VIN2	input	Analog Input 2, single-ended channel with an input range of 0 V to REFIN.
11	AS	input	Logic input address select that chooses one of the I2C addresses depending on the voltage applied (GND, VDD or floating).
12	CONVST	input	Edge-triggered convert start input: the rising edge powers up the part (1 µs power-up time) and the falling edge puts the track/hold in hold mode and starts a conversion.
13	ALERT/BUSY	output	Open-drain digital output selectable as an out-of-range ALERT indicator or a BUSY indicator active during a conversion.
14	SDA	bidirectional	Serial bus bidirectional data I/O, open-drain output requiring an external pull-up resistor.
15	SCL	input	Serial bus clock input requiring an external pull-up resistor.
16	AGND	power_in	Analog ground reference for all circuitry on the AD7993/AD7994; all analog input signals should be referred to this AGND voltage.
