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 Vref+ and Vref– 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.
