Its 180 MHz -3dB bandwidth and 50 V/µs slew rate together define the large-signal transient ceiling — the amplifier reproduces a 20 kHz sine wave at full output swing without slew-rate limiting, preserving harmonic content in the audible band. ## Parametric fit for balanced-line designs The differential output eliminates the need for an external phase splitter when feeding an ADC or driving a twisted-pair cable — the common-mode rejection is built into the output stage. Supply span from 5 V to 32 V covers both single-rail portable gear and ±15 V studio racks; the 14 mA quiescent supply current is the idle draw regardless of signal level, so the thermal budget in a multi-channel mixer card is predictable. Input bias current of 2 µA and input offset voltage of 500 µV set the DC accuracy floor — for a source impedance of 10 kΩ, the bias-current-induced offset is 20 mV, which is well below the clipping margin in a ±15 V system. The 85 mA output current per channel drives the 600 Ω load typical of professional audio inputs without hard clipping into the resistive termination. ## Lifecycle and sourcing posture Texas Instruments lists the OPA1632DR as Active and RoHS3 compliant. The 8-SOIC package is a standard JEDEC footprint, so the PCB land pattern matches the generic SOIC-8 assembly profile used across thousands of BOMs. The laser-etched date-code on genuine TI production matches the plant marking standard — lot traceability is verified on each reel before shipment.","metaTitle":"Texas Instruments OPA1632DR Audio Op-Amp, 180 MHz, 8-SOIC","metaDescription":"Texas Instruments OPA1632DR audio differential op-amp: 180 MHz -3dB bandwidth, 50 V/µs slew rate, 5-32 V supply, 8-SOIC.
