3 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 railto-

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.
