Analog Devices · Analog To Digital Converters (ADCs) · TSSOP-16

AD7796BRUZ 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 SCLK input Serial clock input with a Schmitt-triggered input for data transfers to and from the ADC, which may be continuous or non-continuous.
2 CLK bidirectional Clock in/clock out pin where the internal clock can be made available, or the ADC can be driven by an external clock.
3 CS input Active-low chip select input used to select the ADC, which can be hardwired low for 3-wire operation.
4 NC unconnected No connect pin.
5 AIN(+) input Positive terminal of the differential analog input pair AIN(+)/AIN(-).
6 AIN(-) input Negative terminal of the differential analog input pair AIN(+)/AIN(-).
7 NC unconnected No connect pin.
8 NC unconnected No connect pin.
9 REFIN(+) input Positive reference input that can lie between AVDD and GND + 0.1 V, with a nominal reference of 2.5 V between REFIN(+) and REFIN(-).
10 REFIN(-) input Negative reference input that can lie between GND and AVDD - 0.1 V.
11 NC unconnected No connect pin.
12 GND power_in Ground reference point.
13 AVDD power_in Analog supply voltage, 2.7 V to 5.25 V.
14 DVDD power_in Digital interface supply voltage, 2.7 V to 5.25 V, independent of AVDD.
15 DOUT/RDY output Serial data output that also serves as data ready output, going low to indicate completion of a conversion.
16 DIN input Serial data input that accesses the input shift register of the ADC.
