DC ELECTRICAL CHARACTERISTICS
Typical values are at TA = 25°C. Minimum and Maximum values are for the full operating temperature range: -40 to +85°C for SA575, except SSOP package is tested at +25°C only. VCC = 5V, unless otherwise stated. Both channels are tested in the Expandor mode (see Test Circuit) LIMITS SYMBOL PARAMETER TEST CONDITIONS MIN For compandor, including summing amplifier VCC ICC VREF RL THD ENO 0dB VOS Supply voltage1 Supply current Reference voltage2 Summing amp output load Total harmonic distortion Output voltage noise Unity gain level Output voltage offset Output DC shift 1kHz, 0dB BW = 3.5kHz BW = 20kHz, RS = 0 1kHz No signal No signal to 0dB Gain cell input = 0dB, 1kHz Rectifier input = 6dB, 1kHz Tracking error relative to 0dB Gain cell input = 0dB, 1kHz Rectifier input = -30dB, 1kHz -1.5 -150 -100 -1.0 -1.0 No signal VCC = 5V 3 3 2.4 10 0.12 6 1.5 30 1.5 150 100 1.0 1.0 5 4.2 2.5 7 5.5 2.6 V mA V k % µV dB mV mV dB dB SA575 TYP MAX UNITS
