SUPERIOR SOUND QUALITY

operational amplifiers achieve very low 2.5nV/

√Hz

•

ULTRALOW NOISE: 2.5nV/

√Hz at 1kHz

noise density with an ultralow distortion of 0.00003%

•

ULTRALOW DISTORTION: 0.00003% at 1kHz

at 1kHz. The OPA1602 and OPA1604 series of op

amps offer rail-to-rail output swing to within 600mV

•

HIGH SLEW RATE: 20V/

μs

with 2k

Ω load, which increases headroom and

HIGH OPEN-LOOP GAIN: 120dB

a high output drive capability of

±30mA.

•

UNITY GAIN STABLE

These devices operate over a very wide supply range

•

LOW QUIESCENT CURRENT:

of

±2.25V to ±18V, on only 2.6mA of supply current

2.6mA PER CHANNEL
