DESCRIPTION
The OPA1602 and OPA1604 bipolar-input
operational amplifiers achieve very low 2.5nV/√Hz
noise density with an ultralow distortion of 0.00003%
at 1kHz. The OPA1602 and OPA1604 series of op
amps offer rail-to-rail output swing to within 600mV
with 2kΩ load, which increases headroom and
maximizes dynamic range. These devices also have
a high output drive capability of ±30mA.
These devices operate over a very wide supply range
of ±2.25V to ±18V, on only 2.6mA of supply current
per channel. The OPA1602 and OPA1604 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 OPA1602 and OPA1604 are specified
from –40°C to +85°C. SoundPlus™
