Sound Plus Low Noise and Distortion, General-Purpose, FET-Input Audio Op Amps - OPA1654

OPA1654 (ACTIVE)

Sound Plus Low Noise and Distortion, General-Purpose, FET-Input Audio Op Amps

 

Description

The OPA1652 (dual) and OPA1654 (quad) FET-input operational amplifiers achieve a low 4.5-nV/√Hz noise density with an ultra-low distortion of 0.00005% at 1 kHz. The OPA1652 and OPA1654 op amps offer rail-to-rail output swing to within 800 mV with a 2-kΩ load, which increases headroom and maximizes dynamic range. These devices also have a high output drive capability of ±30 mA.

These devices 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 per channel. The OPA1652 and OPA1654 op amps are unity-gain stable and provide excellent dynamic behavior over a wide range of load conditions.

These devices also feature completely independent circuitry for lowest crosstalk and freedom from interactions between channels, even when overdriven or overloaded.

The OPA1652 and OPA1654 temperature ranges are specified from –40°C to +85°C.
