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 DAC outputs are used to set V_ref+ and V_ref– for
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.
