The TLV5590 analog-to-digital converter is a

system level solution to interface a 4-level

baseband audio signal to a digital decoder. The

FLEX decoder. Designed primarily for pager

applications, the TLV5590 incorporates signal

conditioning, both peak andvalleydetectionalong

with analog-to-digital conversion. A selectable

third-order Butterworth filter with cutoff

frequencies of 1 kHz and 2 kHz is included. The

GND

CON1

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 DAC outputs are used to set V

and V

for the 2-bit analog-to-digital converter (ADC).

Modes of operation include fast track, slow track, hold, and standby. The standby mode maximizes battery life.

The TLV5590 operates on a single supply down to 2.7 V.
