SA58640 datasheet

Description :

The SA58640 is a low-voltage monolithic FM IF system incorporating a mixer/oscillator, two limiting intermediate frequency amplifiers, quadrature detector, logarithmic RSSI, voltage regulator and audio and RSSI operational amplifiers.


1. Low power consumption: 5.0 mA typical at 5 V
2. Mixer input to >100 MHz
3. Mixer conversion power gain of 17 dB at 45 MHz
4. Crystal oscillator effective to 100 MHz (LC oscillator or external oscillator can be used at higher frequencies)
5. 102 dB of IF amplifier/limiter gain
6. 2 MHz IF amplifier/limitersmall signal bandwidth
7. Temperature compensated logarithmic RSSI with a 70 dB dynamic range
8. Low external component count; suitable for crystal/ceramic/LC filters
9. Audio output internal op amp
10. RSSI output internal op amp
11. Internal op amps with rail-to-rail outputs
12. ESD protection: Human body model 2 kV; robot model 200 V
