ADS1255IDBR

Texas Instruments · Analog To Digital Converters (ADC) · SSOP-20-208mil

ADS1255IDBR from Texas Instruments, in a SSOP-20-208mil. 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	AVDD	power_in	Analog power supply, 4.75 to 5.25 V
2	AGND	power_in	Analog ground, 0 V reference
3	VREFN	input	Negative reference input, 0.5 to 2.5 V below VREFP
4	VREFP	input	Positive reference input, 0.5 to 2.5 V above VREFN
5	AINCOM	input	Analog input common for single-ended measurements
6	AIN0	input	Differential or single-ended analog input 0
7	AIN1	input	Differential or single-ended analog input 1
8	SYNC/PDWN	input	Synchronization/power-down input, active low Schmitt-trigger
9	RESET	input	Reset input, active low Schmitt-trigger
10	DVDD	power_in	Digital power supply, 1.8 to 3.6 V
11	DGND	power_in	Digital ground, 0 V reference
12	XTAL2	passive	Crystal oscillator connection, leave floating if external clock input is used
13	XTAL1/CLKIN	input	Crystal oscillator or external clock input, 2 to 10 MHz
14	CS	input	Chip select input, active low Schmitt-trigger
15	DRDY	output	Data ready output, active low indicating new conversion data available
16	DOUT	tri_state	Serial data output, tri-state high impedance when CS is high
17	DIN	input	Serial data input, Schmitt-trigger
18	SCLK	input	Serial clock input, Schmitt-trigger
19	D0/CLKOUT	bidirectional	Digital I/O 0 or clock output, configurable as input or output
