Electrical Characteristics – 5V Supply, TAMB = +25ºC (unless otherwise specified) Symbol Parameter Conditions Min Typ Max Unit VCC Supply Voltage TAMB = -40 to +85ºC 2.7 5.5 V ICC Supply Current 1 1. Quiescent power supply current is specified and tested with no load. Quiescent power supply current depends on the offset voltage when a practical load is connected to the amplifier. VIN- = VIN+ = VBIAS;TAMB = -40 to +85ºC 8 10.4 mA ISHDN Shutdown Supply SHDN = SHDM = GND 0.05 1 µA VIH SHDN, SHDM Threshold 0.7 x VCC V VIL 0.3 x VCC VBIAS Common-Mode Bias Voltage 2 2. Common-mode bias voltage is the voltage on BIAS and is nominally VCC/2. VCC/2 - 5% VCC/2 VCC/2 + 5% V VOS Output Offset Voltage VIN- = VIN+ = VBIAS AV = 0dB (AS1703) ±1 ±10 mV AV = 3dB (AS1704) ±1 ±15 AV = 6dB (AS1705) ±1 ±20 VIC Common-Mode Input Voltage 3 3. Guaranteed by design. Inferred from CMRR Test AV = 0dB (AS1703) 0.2 VCC - 0.2 V AV = 3dB (AS1704) 0.9 VCC - 0.9 AV = 6dB (AS1705) 1.5 VCC - 1.5 External Gain AS1702 1.5 VCC - 1.5 RIN Input Impedance AS1703, AS1704, AS1705 10 15 20 k Ω CMRR Common-Mode Rejection Ratio fN = 1kHz -64 dB PSRR Power Supply Rejection Ratio VIN- = VIN+ = VBIAS; VRIPPLE = 200mVp-p; RL = 8 Ω; CBIAS = 1µF f = 217Hz -79 dB f = 1kHz -73 POUT Output Power 4 4. Guaranteed by design. THD+N = 1%; fIN = 1kHz RL = 8 Ω 0.8 1.25 W RL = 4 Ω 1.8 THD+N Total Harmonic Distortion plus Noise 5 5. Measurement bandwidth for THD+N is 22Hz to 22kHz. RL = 4 Ω, fIN = 1kHz, POUT = 1.28W, VCC = 5V, AV = 6dB 0.06 % RL = 8 Ω, fIN = 1kHz, POUT = 0.9W, VCC = 5V, AV = 6dB 0.03 Gain Accuracy AS1703, AS1704, AS1705 ±1 ±2 % Thermal Shutdown Threshold +145 ºC Thermal Shutdown Hysteresis 9ºC tPU Power-up/Enable from Shutdown Time 125 ms tSHDN Shutdown Time 3.5 µs VPOP Turn-Off Transient 6 6. Peak voltage measured at power-on, power-off, into or out of SHDN. Bandwidth defined by A-weighted filters, inputs at AC GND. VCC rise and fall times ≥ 1ms. 50 mV |
