OPA167x Low-Distortion Audio Operational Amplifiers

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.

1 Features

•

Low noise: 4.5 nV/√Hz at 1 kHz

Low distortion: 0.0001% at 1 kHz

High open-loop gain: 114 dB

High common-mode rejection: 110 dB

Low quiescent current:

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.

– 2 mA per channel

•

Low input bias current: 10 pA (typical)

Slew rate: 9 V/μs

Wide gain bandwidth: 16 MHz (G = 1)

Unity-gain stable

Rail-to-rail output

Wide supply range:

– ±2.25 V to ±18 V, or 4.5 V to 36 V

Single, dual, and quad-channel versions

Available packages:

The OPA167x amplifiers use completely independent

internal circuitry for lowest crosstalk and freedom from

interactions between channels, even when overdriven

or overloaded.

•

– Single: SOIC-8 (preview), SOT-23

– Dual: SOIC-8, small SON-8, VSSOP-8

– Quad: Small QFN-16, SO-14, TSSOP-14

Temperature range: –40°C to +85°C
