Description:
Generally, the output current of NE5532 OPA2604 is less than 50MA, and the output of OPA1611+ Class A after expanding the current is up to 200MA, which greatly increases the driving force, so that the circuit has better collocation, lower output impedance, high and low bass level, and dynamic performance is very good
This product on the basis of 1611, add a pair of NPN PNP complementary symmetrical 500MA current level Philips low noise pipe, so that the output capacity increased by 4 times, and run in a class A state, sound quality is very full, delicate and warm
Transparent, very good analytical power, wide sound field, better than OPA604
The OPA1611 (Single channel) bipolar input op amp achieves very low noise density at 1kHz
(1.1nV/√Hz) and ultra-low distortion (0.000015%). OPA1611 and OPA1612 in 2-k? 6? 8 The ability to provide rail-to-rail output with a swing up to 600mV from the power rail under load helps maximize dynamic range.
These devices support a wide supply voltage range from ±2.25V to ±18V, with only 3.6mA per channel supply current. The OPA1611 operational amplifier offers stable unit gain and excellent dynamic performance over a wide range of load conditions.
It can replace the OPA604 OPA627 NE5534
The following is a comparison of operational amplifier indicators
Main SNR comparison:
OPA1611: Low distortion: 0.000015% (1kHz), low noise: 1.1nV/Hz
OPA604: Low distortion: 0.0003%(1kHz), low noise: 10nV/Hz
