What are the key features of OPA2604IDRQ1?
- AEC-Q100 automotive qualification for reliable operation from -40°C to 125°C in harsh environments
- Ultra-low input bias current of 10 pA at 25°C thanks to FET input stage, minimizing source-impedance errors
- Low total harmonic distortion suitable for high-fidelity audio and precision signal-chain designs
What is OPA2604IDRQ1 used for?
The OPA2604IDRQ1 is ideal for automotive infotainment audio systems, active filters, and precision sensor signal conditioning in vehicle control modules. Its dual-channel FET-input architecture enables low-noise amplification of microphone and audio signals across the full automotive temperature range of -40°C to 125°C. Industrial instrumentation and test equipment also benefit from its high common-mode rejection ratio of 100 dB typical, which suppresses noise in differential measurement paths.

Frequently Asked Questions
What is the input bias current of OPA2604IDRQ1 and why does it matter for high-impedance sensor designs?
The OPA2604IDRQ1 has a maximum input bias current of 100 pA and a typical value of 10 pA at 25°C, enabling accurate amplification of high-impedance sources up to several MΩ without introducing significant offset errors in piezoelectric or pH-sensor front-end circuits.
How does OPA2604IDRQ1 perform in automotive audio applications across its full temperature range?
Rated from -40°C to 125°C and AEC-Q100 qualified, the OPA2604IDRQ1 maintains at least 80 dB CMRR and less than 5 mV input offset voltage across the automotive operating range, ensuring consistent audio fidelity and low distortion in head-unit amplifier stages under hood-temperature extremes.
When is OPA2604IDRQ1 preferred over a BJT-input op-amp for active filter designs?
Designers choose the OPA2604IDRQ1 over BJT-input alternatives when source impedances exceed 100 kΩ, since its 10 pA typical bias current generates under 1 µV of additional offset error. Its voltage-feedback architecture also simplifies Sallen-Key and multiple-feedback filter designs requiring flat gain-bandwidth up to several MHz.
What package does OPA2604IDRQ1 use and how compact is it for dual-channel PCB layouts?
The OPA2604IDRQ1 comes in an 8-pin SOIC package measuring 4.9 mm × 3.9 mm, housing both op-amp channels and requiring only a small PCB footprint. Compared to DIP alternatives, the SOIC outline reduces board area by roughly 60%, which is valuable in space-constrained automotive ECU designs.
