Wadia Buf634 lme49600 Balance To Single-ended, Amp, Analog Output PCB

WADIA buf634 balanced to single-ended (amp) output PCB

wadia buf634 lme49600 balance to single-ended, headphone amp, analog output PCB

Version 1: PCB circuit board (1 piece);

Version 2: BUF634 finished board

Version 3: LME49600 finished board

Specifications: 1: Size: length 80mm*width 80mm

2: PCB fixing screw center hole size: length 74mm and width 74mm

3: Suitable for high-level decoder and pre-level analog output.

4: WADIA's classic decoding analog output solution, taking into account both amp and analog output, sound characteristics: rich in details, in place of emotion, excellent dynamic response and separation, and large sound field scale! (Please note: single op amp can only use OPA606 or OPA627, with output DC voltage zero adjustment potentiometer, OPA627AU is recommended for the best cost-effective solution, and the output buffer chip BUF634 is compatible with LME49600)

5: The signal relay is powered separately, and the analog power supply voltage should not exceed +-15V.

6: RCA standard output level 4V, can also be adjusted to 8V.

Matters needing attention: PCB fixing screw holes are grounded, single op amp can only use OPA606 or OPA627;

(Op amp uses OPA606KP, Vishay tantalum capacitor, NEC signal relay, 1/1000 high precision chip resistor, output buffer chip BUF634)
