853-0594 18663

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.

FEATURES

Indicator (RSSI) with a dynamic range in excess of 90dB

matching network) for 12dB SINAD (Signal to Noise and Distortion

ratio) at 455kHz
