The SA606 is available in 20-lead SOL (surface-mounted small outline large package) and 20-lead SSOP (shrink small outline package). The SA606 was designed for portable communication applications and will function down to 2.7V. The RF section is similar to the famous SA605. The audio and RSSI outputs have amplifiers with access to the feedback path. This enables the designer to level adjust the outputs or add filtering.
