SA604AD/01,112

Overview

The SA604AD/01,112 is a high-performance, low-power FM intermediate frequency (IF) system integrated circuit manufactured by NXP Semiconductors. Designed for mobile and cellular applications, it operates within a supply voltage range of 4.5 V to 8 V and consumes a typical current of 3.3 mA. The device provides a gain of 39 dB at an operating frequency of 25 MHz. It is housed in a 16-lead plastic small outline package (SO16) with a pitch of 1.27 mm. The component supports a wide operating temperature range from -40°C to +85°C and utilizes silicon technology.

Procurement Notes

Verify the specific ordering suffix and manufacturer status before procurement. This component is listed as scheduled for obsolescence or no longer manufactured by NXP. Confirm availability through authorized distributors and check for end-of-life notifications. Ensure the requested part matches the exact SO16 package specification and verify compliance documentation such as RoHS status prior to finalizing orders.

Selection Notes

Select this component for designs requiring an integrated FM IF solution with minimal external passive components. Consider the 4.5 V to 8 V supply range and 3.3 mA current draw when designing power management circuits. Ensure the PCB layout accommodates the 16-SOIC package dimensions. Evaluate thermal requirements given the -40°C to +85°C operating range. Verify compatibility with target RF frequencies around 25 MHz.

Part Context

The SA604A series represents a family of high-performance low-power FM IF systems. The SA604AD variant specifically denotes the DIP or SOIC package configuration within this line. This component serves as a core building block for radio frequency front-end stages in analog and hybrid communication systems, bridging the gap between antenna reception and baseband processing.

Replacement Considerations

Check for direct substitutes within the SA604A family, such as SA604AD/02J, though availability may vary. Consult NXP official documentation for cross-reference lists. Due to obsolescence status, alternative manufacturers' FM IF ICs with similar pinouts and electrical characteristics should be evaluated for functional equivalence.
