Product speciﬁcation

Quadruple ﬁlter DAC

TDA1314T

DC CHARACTERISTICS

VDD = 4.5 to 5.5 V; VDDA = VDDO = 4.75 to 5.25 V; all voltage referenced to ground (pins 6, 7 and 15); measured in test

circuit of Fig.6; Tamb = 25 °C; unless otherwise speciﬁed.

Note

1. RL is the AC impedance of the external circuitry connected to the audio outputs in the application diagram of Fig.6.
