MC34119P

The MC34119P is one member of the MC34119 family which is designed as the low power audio amplifier that is intergrated circuit intended (primarily) for telephone applications, such as in speakerphones. It provides differential speaker outputs to maximize output swing at low supply voltages (2.0 V minimum). Also this device is available in standard 8pin DIP, SOIC package, and TSSOP package.

Features of the MC34119P are:(1)Wide Operating Supply Voltage Range (2.0 V to 16 V), AllowsTelephone Line Powered Applications; (2)Low Quiescent Supply Current (2.7 mA Typ) for Battery Powered Applications; (3)Chip Disable Input to Power Down the IC; (4)Low Power-down Quiescent Current (65 A Typ); (5)Drives a Wide Range of Speaker Loads (8.0 and Up); (6)Output Power Exceeds 250 mW with 32 Speaker; (7)Low Total Harmonic Distortion (0.5% Typ); (8)Gain Adjustable from <0 dB to >46 dB for Voice Band; (9)Requires Few External Components.

The absolute maximum ratings of the MC34119P can be summarized as:(1)Supply Voltage:1.0 to +18 Vdc;(2)Maximum Output Current at VO1, VO2:±250 mA;(3)Maximum Voltage @ Vin, FC1, FC2, CD:1.0, VCC + 1.0 Vdc;(4)Applied Output Voltage to VO1, VO2 when disabled:1.0, VCC + 1.0 Vdc;(5)Junction Temperature:55 to +140 °C.
