Quad op-amp for industrial signal chains
The TLC084AID: With 1.9 mA per channel supply current and 57 mA output drive per channel, it suits multi-channel signal conditioning, active filters, ADC drivers, and control-loop compensation in motor drives, industrial sensors, and test equipment.
The 19 V/µs slew rate supports a full ±10 V output swing up to roughly 300 kHz without visible distortion — adequate for fast-settling analog filters, waveform generation, or driving the input of a 12-bit SAR ADC sampling at a few hundred kSPS. The 10 MHz unity-gain bandwidth gives a closed-loop gain of 10 up to about 1 MHz, so this part can handle audio-band processing, sensor amplification, and moderate-speed control loops without running out of loop gain.
Rated from 4.5 V to 16 V total supply, the TLC084AID can run from a single 5 V or 12 V rail, or split supplies like ±5 V or ±8 V.
Input bias and offset — sensor interface considerations
Input bias current of 3 pA (typical) and input offset voltage of 390 µV (maximum) make the TLC084AID a practical choice for high-impedance sources like photodiodes, pH electrodes, or piezoelectric accelerometers. The 57 mA per-channel output current can drive moderate loads directly — think a 100 Ω resistor to ground or a 10 nF capacitive load with a small series resistor for stability.
Lifecycle and sourcing
It is a current-production part from Texas Instruments, available through independent distribution.
