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.
The Philips SA614A is an improved monolithic low-power FM IF system that incorporates two limiting intermediate frequency amplifiers, a quadrature detector, muting, a logarithmic received signal strength indicator (RSSI), and a voltage regulator. It is designed for applications requiring higher IF bandwidth (25MHz) and temperature-compensated RSSI compared to the SA604.
