• Operating temperature: -40 to +85 °C

Absolute Maximum Ratings:

• Max supply voltage: +14 V
• Max junction/storage temperature: -40 to +125 °C (Storage Temperature Range)

Key Specs:

• Operating current: 2.5 mA typ, 3 mA max (V+ = 5 V, no signal, SW = 0)
• Reference voltage: 2.2 V min, 2.5 V typ, 2.8 V max (V+ = 5 V, no signal)
• Limit level 1: 180 mVrms typ (130 to 230 mVrms, V+ = 5 V, VIN = 1 Vrms, RL = 10 kΩ, f = 1 kHz, Rsense = 8 kΩ)
• Limit level 2: 1.0 Vrms typ (0.7 to 1.3 Vrms, V+ = 13 V, VIN = 2 Vrms, Rsense = 40 kΩ)
• Output noise: -100 dBV (10 μVrms) typ, -90 dBV (31.6 μVrms) max (RS = 0 Ω, A-weighting)
• Total harmonic distortion: 1% max (VIN = 1 Vrms, RL = 10 kΩ, f = 1 kHz, Rsense = 8 kΩ)
