TLC7226CDWR

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

TLC7226CDWR 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 DACB (DAC B output).
2 OUTA output Analog output of DACA (DAC A output).
3 VSS power_in Negative supply voltage input terminal; reference and return terminal for the device (−0.3 V to 24 V).
4 REF input Voltage reference input; determines the full scale analog output (2 V to VDD−4 V).
5 AGND power_in Analog ground; reference and return terminal for the analog signals and supply.
6 DGND power_in Digital ground; reference and return terminal for the digital signals and supply.
7 DB7 input Digital DAC data input bit 7; TTL/CMOS-compatible input for MSB of 8-bit data word.
8 DB6 input Digital DAC data input bit 6; TTL/CMOS-compatible input for 8-bit data word.
9 DB5 input Digital DAC data input bit 5; TTL/CMOS-compatible input for 8-bit data word.
10 DB4 input Digital DAC data input bit 4; TTL/CMOS-compatible input for 8-bit data word.
11 DB3 input Digital DAC data input bit 3; TTL/CMOS-compatible input for 8-bit data word.
12 DB2 input Digital DAC data input bit 2; TTL/CMOS-compatible input for 8-bit data word.
13 DB1 input Digital DAC data input bit 1; TTL/CMOS-compatible input for 8-bit data word.
14 DB0 input Digital DAC data input bit 0; TTL/CMOS-compatible input for LSB of 8-bit data word.
15 WR input Write input; selects DAC transparency (low) or latch mode (high) with minimum pulse duration of 50 ns.
16 A1 input DAC select input; in combination with A0 selects which of four DACs receives data (VIH = 2 V, VIL = 0.8 V).
17 A0 input DAC select input; in combination with A1 selects which of four DACs receives data (VIH = 2 V, VIL = 0.8 V).
18 VDD power_in Positive supply voltage input terminal (11.4 V to 16.5 V recommended operating range).
19 OUTD output Analog output of DACD (DAC D output).
20 OUTC output Analog output of DACC (DAC C output).
