SA614A
Overview
The SA614A is an improved monolithic low-power FM IF system. It incorporates two limiting intermediate frequency amplifiers, quadrature detector, muting, logarithmic received signal strength indicator, and voltage regulator.
- Features and benefits
- Low power consumption: 3.3 mA typical
- Temperature compensated logarithmic RSSI with a 90 dB dynamic range
- Two audio outputs - muted and unmuted
- Low external component count; suitable for crystal/ceramic filters
- Excellent sensitivity: 1.5 V across inputs pins (0.22 V into 50 matching network) for 12 dB SINAD (SIgnal-to-Noise-And-Distortion ratio) for 1 kHz tone with RF at 45 MHz and IF at 455 kHz
- SA614A meets cellular radio specifications
