3 / 13 page  www.austriamicrosystems.com Revision 1.01 3 - 13 AS1702, AS1703, AS1704, AS1705 austriamicrosystems Data Sheet 5V Operation 5 Electrical Characteristics 5.1 5V Operation VCC = 5V, GND = 0V, SHDN = VCC, SHDM = GND, RIN = RF = 10k Ω (AS1702), TAMB = +25°C, CBIAS = 0.1µF, no load. Typical values are at TAMB = +25°C (unless otherwise specified). All specifications are 100% tested at TAMB = +25°C (unless otherwise specified). Specifications over temperature (TAMB = TMIN to TMAX) are guaranteed by design, not production tested. Table 2. Electrical Characteristics – 5V Supply Symbol Parameter Conditions Min Typ Max Unit VCC Supply Voltage 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. Guaranteed by design. VIN- = VIN+ = VBIAS; TAMB = -40 to +85°C, per amplifier 8 10.4 mA ISHDN Shutdown Supply SHDN = SHDM = GND per amplifier 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 Inferred from CMRR Test AV = 0dB (AS1703) 0.5 VCC - 0.5 V AV = 3dB (AS1704) 0.5 VCC - 0.6 AV = 6dB (AS1705) 0.5 VCC - 0.8 External Gain AS1702 0.5 VCC - 1.2 RIN Input Impedance AS1703, AS1704, AS1705 10 15 20 k Ω CMRR Common-Mode Rejection Ration -50 -60 dB fN = 1kHz -64 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 3 3. Output power is specified by a combination of a functional output current test and characterization analysis. THD+N = 1%; fIN = 1kHz RL = 8 Ω 0.8 1.2 W RL = 4 Ω 1.6 THD+N Total Harmonic Distortion plus Noise 4 4. 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 °C Thermal Shutdown Hysteresis 9°C CLOAD Maximum Capacitive Drive Bridge-tied capacitance 500 pF tPU Power-up/Enable from Shutdown Time 125 ms tSHDN Shutdown Time 3.5 µs VPOP Turn-Off Transient 5 5. 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 |
