DAC7614UB

Texas Instruments · Digital To Analog Converters (DAC) · SOIC-16-300mil

DAC7614UB from Texas Instruments, in a SOIC-16-300mil. 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	VDD	power_in	Positive analog supply voltage, +5V nominal.
2	VOUTD	output	DAC D voltage output.
3	VOUTC	output	DAC C voltage output.
4	VREFL	input	Reference input voltage low; sets the minimum output voltage for all DACs, and VREFH must be at least 1.25V greater than VREFL.
5	VREFH	input	Reference input voltage high; sets the maximum output voltage for all DACs.
6	VOUTB	output	DAC B voltage output.
7	VOUTA	output	DAC A voltage output.
8	VSS	power_in	Negative analog supply voltage, 0V or -5V nominal; it must be connected to ground or held within -4.75V to -5.25V.
9	GND	power_in	Ground; the single ground pin that carries all analog and digital return currents.
10	SDI	input	Serial data input; a 16-bit word is shifted in MSB first, containing a 2-bit DAC address, two unused bits, and the 12-bit DAC code.
11	CLK	input	Serial data clock; it is logically ORed with CS to advance the serial shift register.
12	CS	input	Chip select input; it is logically ORed with CLK to advance the serial shift register, and should rise only while CLK is HIGH.
13	NIC	unconnected	Not internally connected.
14	LOADDACS	input	The selected DAC register is transparent when LOADDACS is LOW and latched when LOADDACS is HIGH.
15	RESET	input	Asynchronous reset input; when LOW it sets all DAC registers to zero-scale (000H) or mid-scale (800H) as selected by RESETSEL.
16	RESETSEL	input	Reset code select; when LOW a RESET sets all DAC registers to 000H, and when HIGH a RESET sets them to 800H.
