• Manufacturer Part Number: am79q02
• Description: Quad Subscriber Line Audio-processing Circuit Qslac Devices
• Manufacturer: ETC-unknow

ELECTRICAL CHARACTERISTICS
Typical values are for T
temperature and supply voltage ranges shown in Operating Ranges.
Notes:
1. The CD1, CD2, C3–C5 outputs are resistive for less than a 0.8 V drop. Total current must not exceed absolute maximum ratings.
2. When the digitizer saturates, a resistor of 50 kΩ ±20 kΩ is connected either to DGND or to VCCD — (1 diode drop) as
3. When the QSLAC device is in the Inactive state, the analog output will present either a VREF DC output level through a 15 kΩ
4. If there is an external DC path from VOUT to VIN with a gain of G
5. Power dissipation in the Inactive state is measured with all digital inputs at V
