Overview

The LA1235 is a high integrated IC developed for use in high S/N, low distortion FM IF system applications. This IC features S/N=88dB, distortion factor=0.015% and has almost all functions required for FM tuner IF stage.

Features

• High S/N (88dB typ.).

• Low distortion (0.015% typ.).

• Weak signal muting dirve output having hysteresis.

• Tuning mete null (short) circuit.

• Signal meter dirve output having wide dynamic range.

• High limiting sensitivity.

• Built-in constant-voltage regulated circuit (Operating voltage : 10 to 14V).
