Frequently Asked Questions
What voltage noise specification makes the XOPA1637DGKR suitable for professional audio designs?
The XOPA1637DGKR achieves 3.7 nV/rtHz voltage noise density, which is exceptionally low for a high-voltage op-amp. This noise level ensures a high signal-to-noise ratio in professional audio recording equipment, ADC driver stages, and balanced line receivers operating from supplies up to 36 V.
For a balanced audio interface circuit, how does the XOPA1637DGKR's CMRR performance help reject interference?
The XOPA1637DGKR delivers 140 dB typical CMRR with a minimum of 126 dB, effectively rejecting common-mode noise such as 50 Hz or 60 Hz mains interference in balanced audio lines. This level of rejection is critical for long cable runs in live sound and studio environments where interference rejection directly affects audio quality.
In what temperature environments can the XOPA1637DGKR operate reliably?
The XOPA1637DGKR is rated for -40°C to 125°C operating temperature range, making it suitable for industrial audio processing systems and automotive infotainment applications. The extended temperature range ensures stable 3.7 nV/rtHz noise performance and 126 dB CMRR across varying ambient conditions without additional derating.
What package does the XOPA1637DGKR use and how does it fit compact audio PCB layouts?
The XOPA1637DGKR comes in the 8-VSSOP package, a very small 8-pin outline measuring approximately 3 mm x 3 mm. This compact footprint allows integration into portable audio devices, headphone amplifiers, and multi-channel mixer boards where board space is limited but low-noise 36 V performance is still required.
