PDA381

The PDA381 is low cost dual voltage controlled amplifiers intended for applications requiring high audio performance in a small space. The features of PDA381 are as follows: (1)two high performance VCAs in a minidip; (2)low cost; (3)extremely low noise: >100dB S/N ratio; (4)low distortion: <0.3% THD; (5)low feedthrough: <0.3% of full scale output; (6)easy to use.

The following is about the absolute maximum ratings of PDA381: (1)VCC to VEE: 25V; (2)voltage at any pin: VCC+0.3V to VEE-0.3V; (3)current through any pin: ±50mA; (4)operating temperature range: 0 to 70; (5)storage temperature range: -65 to 150; (6)lead temperature( soldering, 10s): 300 ; (7)power dissipation: 500mW.

The electrical characteristics of the PDA381 are: (1)signal input for 0.2% THD: ±200 A; (2)input summing node D.C. level: -2.1V; (3)max. current gain: 1.0; (4)gain C.V. for max. gain: +5.0V; (5)gain C.V. for -96dB gain: +0.1V; (6)control scale: 20%/V; (7)control scale tempco: ±500 ppm; (8)gain C.V. input bias: -1.5 A; (9)C.V. reference buffer bias: ±100 nA; (10)output voltage compliance for VCA: -0.2V min and +1.0V.
