OPA167x Dual- and Quad-Channel Tool Box Audio Op-Amps

Texas Instruments' low-distortion, low-noise op-amps are ideal for applications such as analog signal conditioning

Image of Texas Instruments' OPA1678/9 Tool Box Audio Op AmpsTexas Instruments' OPA1678 (dual-channel) and OPA1679 (quad-channel) op-amps offer higher system-level performance over legacy op-amps commonly used in audio circuitry. The OPA167x amps achieve a low noise density of 4.5 nV/√Hz and low distortion of 0.0001% at 1 kHz, which improves audio signal fidelity. These devices offer rail-to-rail output swing within 800 mV with a 2 kΩ load which increases headroom and maximizes dynamic range.

The OPA1678 and OPA1679 operate over an ultra-wide supply range of ±2.25 V to ±18 V (4.5 V to 36 V) on 2 mA of supply current to accommodate the power supply constraints of many types of audio products. These op-amps are unity-gain stable and provide excellent dynamic behavior over a wide range of load conditions allowing them to be used in many audio circuits.

The OPA167x amps use completely independent internal circuitry for ultra-low crosstalk and freedom from interactions between channels, even when overdriven or overloaded. The OPA167x offers a temperature range of -40°C to +85°C.
