FM Receiver Specifications
Section 16: FM Receiver Specifications
Note: Values in this data sheet are design goals and are subject to change based on the results of
device characterization.
Unless otherwise stated, limit values apply for the conditions specified inTable 30: “Environmental Ratings,” on
page 126 and Table 32: “Recommended Operating Conditions and DC Characteristics,” on page 127. Typical
values apply for an ambient temperature +25°C.
