Product speciﬁcation

Noise shaping ﬁlter DAC

TDA1386T

DC CHARACTERISTICS

VDDD =VDDA =VDDO =5V; Tamb =5 °C; all voltages referenced to ground (pins 2, 9 and 23); unless otherwise

speciﬁed

Notes

1. All power supply pins (VDD and GND) must be connected to the same external power supply unit.

2. RL is the AC impedance of the external circuitry connected to the audio outputs of the application circuit.
