ADC78H90CIMTX

Texas Instruments · Global Sourcing Parts · TSSOP-16

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.
