Unity gain level programmable low power compandor
Product specification
SA577
DESCRIPTION
The SA577 is a unity gain level programmable compandor designed
for low power applications. The SA577 is internally configured as an
expandor and a compressor to minimize external component count.
FEATURES
• Operating voltage range: 1.8V to 7V
• Low power consumption (1.4mA @ 3.6V)
• 0dB level programmable (10mV_RMS to 1.0V_RMS)
• Over 90dB of dynamic range
• Wide input/output swing capability (rail-to-rail)
• Low external component count
• SA577 meets cellular radio specifications
• ESD hardened
