3 / 32 page  TS419-TS421 3/32 FIXED GAIN VERSION SPECIFIC ELECTRICAL CHARACTERISTICS V CC from +5V to +2V, GND = 0V, Tamb = 25°C (unless otherwise specified) APPLICATION COMPONENTS INFORMATION TYPICAL APPLICATION SCHEMATICS: Symbol Parameter Min. Typ. Max. Unit RIN Input Resistance 20 k Ω G Gain value for Gain TS419/TS421-2 Gain value for Gain TS419/TS421-4 Gain value for Gain TS419/TS421-8 6dB 12dB 18dB dB Components Functional Description RIN Inverting input resistor which sets the closed loop gain in conjunction with RFEED. This resistor also forms a high pass filter with CIN (fcl = 1 / (2 x Pi x RIN x CIN)). Not needed in fixed gain versions. CIN Input coupling capacitor which blocks the DC voltage at the amplifier’s input terminal RFEED Feedback resistor which sets the closed loop gain in conjunction with RIN. AV= Closed Loop Gain= 2xRFEED/RIN. Not needed in fixed gain versions. CS Supply Bypass capacitor which provides power supply filtering. CB Bypass capacitor which provides half supply filtering. |
