Features

• Non-adjusting VCO : Eliminates the need to adjust free-

running frequency.

• VCO is stable to ambient temperature changes : ±0.1 to

0.15% for ±50°C change.

• Low distortion (0.07% typ./300mV input, mono).

• Good ripple rejection of power supply (35dB typ.).

• Wide operating voltage range (VCC=6.5 to 13V).

• Good space factor due to single-end package.

• Easy to draw printed circuit pattern due to pin-to-pin space

of 3mm.
