OPA169x Low-Power, Low-Noise and Low-Distortion SoundPlus ™ Audio Operational Amplifiers 1 Features 3 Description
• Low Noise: 4.2 nV/√Hz at 1 kHz The OPA169x operational amplifiers achieve a new 1 level of performance for low-power amplifiers with a • Low Distortion: –127 dB at 1 kHz low 4.2-nV/√Hz noise density and distortion of –127 • Low Quiescent Current: dB at 1 kHz. These op amps offer rail-to-rail output 650 µA per Channel swing to within 200 mV of the power supplies with a • Slew Rate: 23 V/μs 2-kΩ load, which increases headroom and maximizes dynamic range. These devices have a high output • Wide Gain Bandwidth: 5.1 MHz drive capability of ±50 mA. • Unity-Gain Stable The OPA169x operational amplifiers operate over a • Rail-to-Rail Output wide supply range of ±1.75 V to ±18 V, or 3.5 V to 36 • Wide Supply Range: V (on 650 µA of supply current per channel), are ±1.75 V to ±18 V, or 3.5 V to 36 V unity-gain stable, and provide excellent dynamic behavior over a wide range of load conditions.
2 Applications
The OPA169x op amps are specified for a • Wireless Microphones temperature range of –40°C to 125°C. • Wireless Audio Monitoring Systems
Device Information(1)
