Parametric fit for balanced audio signal chains
The OPA1632D: The differential output directly drives balanced lines (XLR, TRS) without external phase-splitter stages. Supply current is 14 mA typical, and each output channel can deliver 85 mA — enough to drive a line-level load or a low-impedance headphone buffer with margin. Input offset voltage is 500 µV max, and input bias current is 2 µA, both within the range for precision audio front-ends.
Temperature range and package for PCB integration
The supply voltage span is 5 V minimum to 32 V maximum, so it runs on common audio rails (±2.5 V to ±16 V). The single-circuit topology means one device per channel; a stereo design uses two OPA1632D devices.
Sourcing and compliance
The OPA1632D is ROHS3 compliant.
