8-SOIC footprint and what it drives on the board
The TL3472CDR comes in an 8-SOIC package with a 0.154-inch body width and 3.90 mm width, surface-mount only. The 1.27 mm pin pitch is standard for SOIC-8, so the footprint matches any generic SOIC-8 land pattern — no custom pad geometry needed. The supplier device package is 8-SOIC, meaning the same mechanical outline serves across TI's SOIC-8 op amps, easing last-minute BOM swaps without a board spin.
Slew rate and gain bandwidth — the signal chain ceiling
Rated at 13 V/µs slew rate and 4 MHz gain-bandwidth product, this dual op amp handles fast edges in analog signal conditioning. The 13 V/µs rate means a 10 V peak-to-peak output step settles in under 0.8 µs — fast enough for audio processing, motor-current sensing, or ADC driver stages where the input signal changes at tens to hundreds of kHz. The 4 MHz GBW sets the closed-loop bandwidth: at a gain of 10, the -3 dB point lands around 400 kHz, which covers most sensor and control-loop frequencies without rolling off the signal.
Supply current, input bias, and offset — what they mean for the BOM
Each channel draws 3.5 mA supply current, so the dual device pulls 7 mA total from the rail — a modest load for a 4 V to 36 V supply span. The 100 nA input bias current is typical for a bipolar-input op amp; it matters when the source impedance exceeds 100 kΩ, where the bias current multiplied by the source resistance creates a DC offset error comparable to the 1 mV input offset voltage. The 34 mA output current per channel drives moderate loads like a 100 Ω feedback network or a 10-bit ADC input without external buffer.
Active production and compliance status
It is ROHS3 compliant, so it meets the current EU restriction directive for lead and other substances. The operating temperature range is 0°C to 70°C, which suits commercial and indoor equipment; for extended industrial or automotive temperature, a different grade would be needed.
