Description
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. The SA58640 is available in
a 20-pin SSOP package.
