ADC78H90CIMTX from Texas Instruments, in a TSSOP-16. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | CS | input | Chip select; on the falling edge of CS, a conversion process begins and conversions continue as long as CS is held low. |
| 2 | AVDD | power_in | Positive analog supply pin; connect to +2.7V to +5.25V source and bypass with 1 µF tantalum and 0.1 µF ceramic capacitors within 1 cm of the power pin. |
| 3 | AGND | power_in | Ground return for the analog supply and signals. |
| 4 | AIN1 | input | Analog input 1; input voltage range 0V to AVDD. |
| 5 | AIN2 | input | Analog input 2; input voltage range 0V to AVDD. |
| 6 | AIN3 | input | Analog input 3; input voltage range 0V to AVDD. |
| 7 | AIN4 | input | Analog input 4; input voltage range 0V to AVDD. |
| 8 | AIN5 | input | Analog input 5; input voltage range 0V to AVDD. |
| 9 | AIN6 | input | Analog input 6; input voltage range 0V to AVDD. |
| 10 | AIN7 | input | Analog input 7; input voltage range 0V to AVDD. |
| 11 | AIN8 | input | Analog input 8; input voltage range 0V to AVDD. |
| 12 | DGND | power_in | Ground return for the digital supply and signals. |
| 13 | DVDD | power_in | Positive digital supply pin; connect to +2.7V to AVDD supply and bypass with 0.1 µF ceramic capacitor within 1 cm of the power pin. |
| 14 | DIN | input | Digital data input; the ADC78H90's Control Register is loaded through this pin on rising edges of the SCLK pin. |
| 15 | DOUT | output | Digital data output; output samples are clocked out on falling edges of the SCLK pin in straight binary format. |
| 16 | SCLK | input | Digital clock input; frequency range 50 kHz to 8 MHz; directly controls the conversion and readout processes. |
