EUA6204 ds6204 ver1.1 june. 2006 9 application information application schematics figure14 through figure15 show application schematics for differential and single-ended inputs. typical values are shown in table1. table1. typical component value component value r i 40k ? c (bypass) 0.22f c s 1f c i 0.22f power dissipation power dissipation is a major concern when designing a successful amplifier, whether the amplifier is bridged or single-ended. a direct consequence of the increased power delivered to the load by a bridge amplifier is an increase in internal power dissipation. since the EUA6204 has two operational amplifiers in one package, the maximum internal power dissipation is 4 times that of a single-ended amplifier. the maximum power dissipation for a given application can be derived from the power dissipation graphs of from equation1. ------------(1) it is critical that the maximum junction temperature t jmax of 150c is not exceeded. t jmax can be determine from the power derating curves by using p dmax and the pc board foil area. by adding additional copper foil, the thermal resistance of the application can be reduced, resulting in higher p dmax. additional copper foil can be added to any of the leads connected to the EUA6204. if t jmax still exceeds 150c, then additional changes must be made. these changes can include reduced supply voltage, higher load impedance, or reduced ambient temperature. internal power dissipation is a function of output power. proper selection of external components gain-setting resistor selection the input resistor (r i ) can be selected to set the gain of the amplifier according to equation2. gain=r f /r i (2) the internal feedback resistors (r f ) are trimmed to 40k ? . resistor matching is very important in fully differential amplifiers. the balance of the output on the reference voltage depends on matched ratios of the resistors. cmrr, psrr, and the cancellation of the second harmonic distortion diminishes if resistor mismatch occurs. therefore, it is recommended to use 1% tolerance resistors or better to keep the performance optimized. bypass capacitor (c bypass ) and start-up time the internal voltage divider at the bypass pin of this device sets a mid-supply voltage for internal references and sets the output common mode voltage to v dd /2. adding a capacitor to this pin filters any noise into this pin and increases k svr. c (bypass) also determines the rise time of v o+ and v o- when the device is taken out of shutdown. the larger the capacitor, the slower the rise time. show the relationship of c (bypass) to start-up time as figure10. ) r /(2 ) (v * 4 p l dd dmax 2 2 = www.datasheet.in
EUA6204 ds6204 ver1.1 june. 2006 10 input capacitor (c i ) the EUA6204 does not require input coupling capacitors if using a differential input source that is biased from 0.5v to v dd -0.8v. use 1% tolerance or better gain-setting resistors if not using input coupling capacitors. in the single-ended input application an input capacitor, c i , is required to allow the amplifier to bias the input signal to the proper dc level. in this case, c i and r i form a high-pass filter with the corner frequency determined in equation3. (3) the value of c i is important to consider as it directly affects the bass (low frequency) performance of the circuit. consider the example where r i is 10k ? and the specification calls for a flat bass response down to 100hz. equation 3 is reconfigured as equation4. (4) in this example, c i is 0.16f, so one would likely choose a value in the range of 0.22f to 0.47f. ceramic capacitors should be used when possible, as they are the best choice in preventing leakage current. when polarized capacitors are used, the positive side of the capacitor should face the amplifier input in most applications, as the dc level there is held at v dd /2, which is likely higher than the source dc level. it is important to confirm the capacitor polarity in the application. decoupling capacitor (c s ) the EUA6204 is a high-performance cmos audio amplifier that requires adequate power supply decoupling to ensure the output total harmonic distortion (thd) is as low as possible. power supply decoupling also prevents oscillations for long lead lengths between the amplifier and the speaker. for higher frequency transients, spikes, or digital hash on the line, a good low equivalent-series-resistance (esr) ceramic capacitor, typically 0.1f to 1 f, placed as close as possible to the device v dd lead works best. for filtering lower frequency noise signals, a 10-f or greater capacitor placed near the audio power amplifier also helps, but is not required in most appli cations because of the high psrr of this device. i c i r 2 1 c f = c f i r 2 1 i c = www.datasheet.in
