A NEW I/V CONVERSION AND OUTPUT STAGE FOR WEISS FLAGSHIP MEDEA+
DIGITAL TO ANALOGUE CONVERTER
Superb noise performance:
1nV/√Hz voltage noise density (1kHz)
30nVpp voltage noise (0.1-10Hz)
0.7pA/√Hz current noise density (1kHz)
80pApp current noise (0.1-10Hz)
no common-mode current noise from bias cancellation
Outstanding distortion specifications:
THD+N -152dB (+20dBu, 1kHz, 22kHz BW, 600Ω)
THD+N -148dB (+20dBu, 10kHz, 80kHz BW, 600Ω)
distortion spectrum consists almost entirely of 2nd and 3rd harmonic
no significant crossover distortion, even with 200Ω load
no significant common mode distortion, even with very high source impedances
Impressive AC performance:
50V/µs slew rte, highly symmetrical
95MHz gain bandwidth product
700kHz power bandwidth (20Vpp into 600Ω)
300kHz power bandwidth (20Vpp into 200Ω)
Superior DC precision:
offset 10µV
input bias current +-60nA
input offset current +-10nA
Excellent load driving capability:
27Vpp(+21.8dBu) in 200Ω (+-15V supply)
20Vpp(+19.2dBu) in 100Ω (+-15V supply)
10Vpp(+13.2dBu) in 50Ω (+-15V supply)
adjustable class A output current, factory trimmed to 30mA
very low output impedance
extensive short-circuit protection
Salient insensitivity to power supply deficiencies:
very high PSRR with little degradtion towards high frequencies
individual RC decoupling of amplifier sub-circuits eliminates the interaction
of the various amplifier stages and makes the amplifier insensitive to power
supply inductance
high performance on-board decoupling capacitors, 2.4µF total
no need for additional external decoupling capacitors
recommended power supply range from +-5V to +-18V
Carefully thermal design:
excellent stability of any bias condition
full thermal isolation of the sensitive input stage from the power output
stage
fast settling of bias conditions after start up
Dimensions:
42 x 28 x 17mm (1.65 x 1.1 x 0.67 inches)
API2520 standard pinout
