Note 1) The circuit GND pin is used as the reference for all voltages.
Note 2) Substrate mounting (Sony's standard pattern on a 50 mm
50 mm, 1.6 mm thick glass fabric base
epoxy substrate) and no-wind conditions.
Total power dissipation follows a load reduction ratio of 8.2 mW/C at temperatures above Ta = 25 C.

Application Circuit
Note)
Pins 23 and 26 are detection level setting pins for SP/LP DET
and CLOG DET, respectively. Set the detection levels to the
optimal values for the set.
When not using these identification blocks, the signal input to
Pin 30 (SPIN) and other related peripheral components are also
unnecessary.
Sony reserves the right to change products and specifications without prior notice. This information does not convey any license by
