ORDERING INFORMATION

KTXN

78

I

Low-voltage DAA analog differential negative input

TXN

79

O

Codec negative analog output. The DC level is Vcm, and the full-scale ac output is 2.8V p-p±5%. The maximum loading

is 1k

Ω, in parallel with 20 pF for modem applications. For audio applications with low-impedance load, the maximum

distortion-free (THD <–60-db) current is 10 mA rms.

TXP

80

O

Codec positive analog output. The DC level is Vcm, and the full-scale ac output is 2.8V p-p±5%. The maximum loading is

1k

Ω, in parallel with 20 pF for modem applications. For audio applications with low-impedance load, the maximum

distortion-free (THD <–60-db) current is 10 mA rms.
