description

The Texas Instruments (TI

™) TLV5592 analog-to-

digital converter (ADC) is a system level solution

to interface a 4-level baseband audio signal to a

digital decoder. The TLV5592 is a direct interface

to the TLV559X FLEX decoder. Designed primari-

ly for messaging applications, the TLV5592 incor-

porates signal conditioning, both peak and valley

detection along with analog-to-digital conversion.

A selectable third-order Butterworth filter with

cutoff frequencies of 1 kHz and 2 kHz is included.

The peak and valley detectors are implemented

with a unique design that does not require external

capacitors. Two 8-bit digital-to-analog converters

(DACs) are used in a feedback loop to

automatically adjust to the peak and valley levels.

the 2-bit ADC. Modes of operation include fast

track, slow track, hold, and standby. The standby

mode maximizes battery life. The TLV5592

operates on a single power supply from 1.8 V to

2.5 V.
