TLC7226IDWR

Texas Instruments · Digital To Analog Converters (DACs) · SOIC-20-300mil

TLC7226IDWR from Texas Instruments, in a SOIC-20-300mil. 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	OUTB	output	Analog output of DAC channel B, capable of sourcing up to 5 mA output current.
2	OUTA	output	Analog output of DAC channel A, capable of sourcing up to 5 mA output current.
3	VSS	power_in	Negative supply voltage input, range −5.5 to 0 V, must be tied to the most negative supply voltage applied to device.
4	REF	input	Voltage reference input determining full-scale analog output, operating range 0 to VDD−4 V.
5	AGND	power_in	Analog ground terminal serving as reference and return for analog signals and supply.
6	DGND	power_in	Digital ground terminal serving as reference and return for digital signals and supply.
7	DB7	input	Most significant bit (MSB) of 8-bit digital data input bus, TTL/CMOS compatible, VIH ≥ 2 V.
8	DB6	input	Bit 6 of 8-bit digital data input bus, TTL/CMOS compatible, VIH ≥ 2 V.
9	DB5	input	Bit 5 of 8-bit digital data input bus, TTL/CMOS compatible, VIH ≥ 2 V.
10	DB4	input	Bit 4 of 8-bit digital data input bus, TTL/CMOS compatible, VIH ≥ 2 V.
11	DB3	input	Bit 3 of 8-bit digital data input bus, TTL/CMOS compatible, VIH ≥ 2 V.
12	DB2	input	Bit 2 of 8-bit digital data input bus, TTL/CMOS compatible, VIH ≥ 2 V.
13	DB1	input	Bit 1 of 8-bit digital data input bus, TTL/CMOS compatible, VIH ≥ 2 V.
14	DB0	input	Least significant bit (LSB) of 8-bit digital data input bus, TTL/CMOS compatible, VIH ≥ 2 V.
15	WR	input	Write input; latches data on rising edge while low level makes selected latch transparent, VIH ≥ 2 V.
16	A1	input	Address input bit 1; combined with A0 selects which DAC (A, B, C, or D) receives data, VIH ≥ 2 V.
17	A0	input	Address input bit 0; combined with A1 selects which DAC (A, B, C, or D) receives data, VIH ≥ 2 V.
18	VDD	power_in	Positive supply voltage input, recommended range 11.4 to 16.5 V for dual supply operation.
19	OUTD	output	Analog output of DAC channel D, capable of sourcing up to 5 mA output current.
20	OUTC	output	Analog output of DAC channel C, capable of sourcing up to 5 mA output current.
