DESCRIPTION
The OPA1662 (dual) and OPA1664 (quad) series of
bipolar-input operational amplifiers achieve a low 3.3
nV/√Hz noise density with an ultralow distortion of
0.00006% at 1 kHz. The OPA1662 and OPA1664
series of op amps offer rail-to-rail output swing to
within 600 mV with 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 ±1.5 V to ±18 V, or +3 V to +36 V, on only 1.5 mA
of supply current per channel. The OPA1662 and
OPA1664 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 OPA1662 and OPA1664 are specified
from –40°C to +85°C. SoundPlus™
