3 Description

The single-channel OPA1677, dual-channel

OPA1678, and quad-channel OPA1679 (OPA167x)

op amps offer higher system-level performance over

legacy op amps commonly used in audio circuitry.

The OPA167x amplifiers achieve a low 4.5-nV/√Hz

noise density and low distortion of 0.0001 at 1 kHz,

which improves audio signal fidelity. These devices

also offer rail-to-rail output swing to within 800 mV

with a 2-kΩ load, which increases headroom and

maximizes dynamic range.

To accommodate the power-supply constraints of

many types of audio products, the OPA167x operate

over a very-wide supply range of ±2.25 V to ±18 V

(or 4.5 V to 36 V) on only 2 mA of supply current.

These op amps are unity-gain stable and have

excellent dynamic behavior over a wide range of load

conditions, allowing the OPA167x to be used in many

audio circuits.

The OPA167x amplifiers use completely independent

internal circuitry for lowest crosstalk and freedom from

interactions between channels, even when overdriven

or overloaded.
