产品描述

The SA616 is a low-voltage high performance monolithic FM IF system incorporating a mixer/oscillator, two limiting intermediate frequency amplifiers, quadrature detector, logarithmic Received Signal Strength Indicator (RSSI), voltage regulator and audio and RSSI op amps. The SA616 is available in SSOP20 and HVQFN20 packages.

The SA616 was designed for portable communication applications and will function down to 2.7 V. The RF section is similar to the famous SA615. The audio and RSSI outputs have amplifiers with access to the feedback path. This enables the designer to adjust the output levels or add filtering.
