OPA1612-Q1 Precision Audio Amplifier Texas Instruments OPA1612-Q1 Precision Audio Amplifier is a dual, SoundPlus, bipolar-input operational amplifier. This amplifier achieves very low noise density with an ultra-low distortion. The OPA1612-Q1 device offers rail-to-rail output swing to within 600mV with a 2kΩ load. This output swing increases headroom and maximizes dynamic range. These devices also have a high output drive capability of ±30mA. Each amplifier operates over a very wide supply range of ±2.25V to ±18V, on only 3.6mA of supply current per channel. The OPA1612-Q1 op amp is unity-gain stable and provide excellent dynamic behavior over a wide range of load conditions.
