What the TLC7226IDW is and where it fits
The TLC7226IDW from Texas Instruments is a quad 8-bit digital-to-analog converter with voltage-buffered outputs, built around an R-2R ladder architecture. It packs four independent DACs in a single 20-SOIC wide-body package, each with its own output buffer, so you can set four analog voltages from a single digital bus. The parallel data interface means you write all eight bits at once — no serial clock, no shift-register delay — which makes it a natural fit for microprocessor or FPGA systems where you need to update multiple analog channels simultaneously, such as in industrial process control, automated test equipment, or multi-axis motion controller trim voltages.
Key ratings and what they mean for your BOM
Analog supply requires 11.4 V to 16.5 V positive rail and -5.5 V negative rail. Operating temperature range is -30°C to 85°C.
Package and layout
The 20-SOIC wide-body package (0.295-inch body width, 7.50 mm) is a standard surface-mount footprint. The wider body gives more room between pins than the narrow SOIC-20, which helps with manual rework or inspection.
Sourcing and lifecycle
No end-of-life notice or last-time-buy window is on record.
