Jung Super POWER Circuit Super Linear Power Supply Ground DAC Preamplifier Voltage Regulator
Circuit reference from Jung,Walt Jung has been developing regulators since 1961
Very low noise, very low output impedance, very suitable for preamplifier, DAC precision power supply use. It may be one of the few discrete (All discrete) regulator circuits today!
Do not use the simple three-terminal LDO, the experimental results tell us that this is not a rival, regardless of the mania, response, impedance, SJR can be said to be a great victory!
Parameters：Input power range: AC7X2-AC18X2Output voltage range: ± 5V-- ± 18VPCB size: 81X61mm Maximum output current: 2AThe PCB is a finished board, has been well tested, warranty for six months.Material：Rectifier for low voltage drop high speed regulator diode, main filter for ELNA, output tube for MJE15032, MJE15033, operational amplifier for OPA1611.The bipolar input operational amplifier OPA1611 (single channel) can achieve a very low noise density at 1 kHz
(1.1nV/√Hz) and extremely low distortion (0.000015%) at 1kHz. The OPA1611 and OPA1612 offer rail-to-rail outputs with a 600mV swing from the supply rail at a 2-k?6?8 load, which helps maximize dynamic range. In addition, these devices offer a high output drive capability of ±30mA.These devices support a wide supply voltage range of ±2.25V to ±18V with a supply current of only 3.6mA per channel. The OPA1611 op amps have stable gain per unit to ensure excellent dynamic performance over a wide range of load conditions.Can replace OPA604 OPA627 NE5534Key signal-to-noise ratio comparisons：
OPA1611: Low distortion: 0.000015% (1kHz), low noise: 1.1nV/Hz
OPA604: Low distortion: 0.0003 %(1kHz), Low noise: 10nV/HzPacking：
