Dual Automotive, Audio Line Drivers

with I C Control and Diagnostic

General Description

Features

S Comprehensive Programmability and Diagnostics

The MAX13325/MAX13326 dual audio line drivers provide

a reliable differential interface between automotive audio

components. The devices feature differential inputs and

outputs, integrated output diagnostics, and are controlled

using an I²C interface or operate in stand-alone mode.

Using I²C Interface

S Autoretry Function in Stand-Alone Mode

S Drive Capacitive Loads ≤ 3nF Differentially, ≤ 4nF

to Ground

The outputs can deliver up to 4V

into 100Iloads.

RMS

S 112dB Signal-to-Noise Ratio

The MAX13325 buffers analog audio signals for trans-

mission over long cable distances with a fixed gain of

12dB, whereas the MAX13326 provides a 0dB fixed

gain. The diagnostics on the outputs report conditions

on a per channel basis, including short to GND, short

to battery, overcurrent, overtemperature, and excessive

offset. The output amplifiers can drive capacitive loads

up to 4nF to ground and 3nF differentially.

S Low 0.002% THD at 4V

into 2.7kI Loads

RMS

S High PSRR (70dB at 1kHz)

S High CMRR (80dB at 1kHz)

S Low Output Noise (3µV

), MAX13326

RMS

S Excellent Channel-to-Channel Matching

S Load-Dump Transient Protection

S Protected Output Against Various Short-Circuit

The outputs are protected according to IEC 61000-4-2

Q8kV Contact Discharge, and Q15kV Air Gap. The

MAX13325/MAX13326 are specified from -40NC to

+105NC and are available in a 28-pin TSSOP package

with an exposed pad.

Conditions

S ESD Protection for 8kV Contact Discharge,

1ꢀkV Air Gap

S Long-Distance Drive Capability Typically Up to

1ꢀm or Greater

Applications

Automotive Radio and Rear Seat Entertainment

Professional Remote Audio Amplifiers

S Noise-Rejecting Differential Inputs and Outputs

S Low-Power Shutdown Mode < 10µA

S Hardware or Software MUTE Function

S 28-Pin TSSOP Package with Exposed Pad
