DESCRIPTION
The SA614A is an improved monolithic low-power FM IF system
incorporating two limiting intermediate frequency amplifiers,
quadrature detector, muting, logarithmic received signal strength
indicator, and voltage regulator. The SA614A features higher IF
bandwidth (25MHz) and temperature compensated RSSI and
limiters permitting higher performance application compared with the
SA604. The SA614A is available in a 16-lead dual-in-line plastic
and 16-lead SO (surface-mounted miniature) package.
