MCP3208T-BI from Microchip Tech, in a SOIC-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	CH0	input	Analog input channel 0, programmable as single-ended or as one input of a pseudo-differential pair.
2	CH1	input	Analog input channel 1, programmable as single-ended or as one input of a pseudo-differential pair.
3	CH2	input	Analog input channel 2, programmable as single-ended or as one input of a pseudo-differential pair.
4	CH3	input	Analog input channel 3, programmable as single-ended or as one input of a pseudo-differential pair.
5	CH4	input	Analog input channel 4 (MCP3208 only), programmable as single-ended or as one input of a pseudo-differential pair.
6	CH5	input	Analog input channel 5 (MCP3208 only), programmable as single-ended or as one input of a pseudo-differential pair.
7	CH6	input	Analog input channel 6 (MCP3208 only), programmable as single-ended or as one input of a pseudo-differential pair.
8	CH7	input	Analog input channel 7 (MCP3208 only), programmable as single-ended or as one input of a pseudo-differential pair.
9	DGND	power_in	Digital ground connection to the internal digital circuitry, to be connected to VSS or the analog ground plane as described in section 6.5.
10	CS/SHDN	input	Chip select/shutdown: pulled low to start communication, pulled high to end a conversion and enter low-power standby; must be high between conversions.
11	DIN	input	SPI serial data input used to load channel configuration data into the device.
12	DOUT	output	SPI serial data output that shifts out the A/D conversion results; data changes on the falling edge of each clock.
13	CLK	input	SPI serial clock that initiates a conversion and clocks out each bit of the result; clock speed constraints apply per section 6.2.
14	AGND	power_in	Analog ground connection to the internal analog circuitry.
15	VREF	power_in	Reference voltage input for the A/D converter; the valid voltage range is not stated in this pin table.
16	VDD	power_in	Power supply input, +2.7V to 5.5V.
