OPA1662AIDGKRQ1

Instrumentation, Op Amps, Buffer Amps Overview

The OPA1662AIDGKRQ1 is a dual-channel, low-noise audio operational amplifier from Texas Instruments' SoundPlus series. Designed for automotive applications, it features bipolar inputs and rail-to-rail output capability. Key electrical parameters include a gain-bandwidth product of 22 MHz, a slew rate of 17 V/µs, and a supply current of 1.5 mA per two channels. It operates within a voltage range of 3 V to 36 V and supports an operating temperature range of -40°C to 85°C.

Instrumentation, Op Amps, Buffer Amps Feature Summary

• Automotive-grade qualification compliant with AEC-Q100 standards
• Ultra-low total harmonic distortion plus noise performance
• Rail-to-rail output swing for maximum dynamic range
• Low power consumption suitable for battery-operated systems

Instrumentation, Op Amps, Buffer Amps Applications

• Automotive audio signal processing circuits
• Active crossovers in vehicle sound systems
• Headrest entertainment system amplifiers
• Center channel speaker pre-amplification

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the Q1 suffix confirms AEC-Q100 automotive qualification status. Ensure the DGKR package designation matches the required 8-VSSOP footprint for PCB layout compatibility. Confirm that the specified operating temperature range meets the thermal requirements of the intended automotive zone. Cross-reference the manufacturer part number with authorized distributors to ensure authenticity and traceability.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when automotive reliability is mandatory alongside high-fidelity audio performance. The dual-channel configuration reduces board space compared to single-channel alternatives. Consider the 22 MHz bandwidth for applications requiring wide frequency response without excessive phase shift. Evaluate the 1.5 mA supply current against system power budget constraints for portable or energy-efficient automotive designs.

Instrumentation, Op Amps, Buffer Amps Part Context

This device belongs to the OPA166x family of SoundPlus audio operational amplifiers. It shares core architectural similarities with the non-automotive OPA1662AIDGKR but includes enhanced testing and documentation for automotive environments. The family is characterized by its bipolar input stage technology, which contributes to superior noise and distortion metrics compared to CMOS-based audio amplifiers.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

The OPA1662AIDGKR serves as the commercial-grade equivalent. Verify if the specific automotive qualification is required for the application. Other members of the OPA166x family may offer different channel counts or pinouts.
