Product details

Description

AS2504 is a CMOS integrated circuit that incorporates DC and AC line adaptation (DCmask and synthesised AC-impedance of 1000Ω) as well as a speech circuit with softclipping, line loss compensation and Rxvolu

Features

Analogue line interface and speech circuit for a/b terminals on a 28-pin CMOS-IC 2 balanced transmit inputs 3 unbalanced transmit inputs 2 buffered single ended receive outputs (RL>150Ω) 1 auxiliary single ended receive output (RL>10kΩ) Low noise (max. -72dBmp) Soft clipping to avoid harsh distortion Operating range from 15mA to 100mA (down to 5mA with reduced performance) Line loss compensation selectable by pin option Real and complex impedance selectable by external compon.
