Product Summary

The SA614AD 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 SA614AD features higher IF bandwidth (25MHz) and temperature compensated RSSI and limiters permitting higher performance application compared with the SA604. The SA614AD is available in a 16-lead dual-in-line plastic and 16-lead SO (surface-mounted miniature) package. The applications of the SA614AD are (1)Cellular radio FM IF; (2)High performance communications receivers; (3)Intermediate frequency amplification and detection up to 25MHz; (4)RF level meter; (5)Spectrum analyzer; (6)Instrumentation; (7)FSK and ASK data receivers.

Parametrics

SA614AD absolute maximum ratings: (1)VCC Single supply voltage 9 V; (2)TSTG Storage temperature range -65 to +150℃; (3)TA Operating ambient temperature range -40 to +85℃; (4)θJA Thermal impedance: 90℃/W.

Features

SA614AD features: (1)Low power consumption: 3.3mA typical; (2)Temperature compensated logarithmic Received Signal Strength Indicator (RSSI) with a dynamic range in excess of 90dB; (3)Two audio outputs - muted and unmuted; (4)Low external component count; suitable for crystal/ceramic filters; (5)Excellent sensitivity: 1.5μV across input pins (0.22μV into 50? matching network) for 12dB SINAD (Signal to Noise and Distortion ratio) at 455kHz; (6)SA614A meets cellular radio specifications.
