www.austriamicrosystems.com/audio/opamps/as1710_12 revision 1.9 10 - 19 as1710/as1712 datasheet - application information 8 application information 8.1 package power dissipation caution: due to the high output current drive, this op-amp can exceed the absolute maximum power-dissipation rating. normally, when peak current is less than or equal to 40ma the maximum package power dissipation is not exceeded for any of the package types offered. the absolute maximum power-dissipation rating of each package should always be verified. (eq 1) gives an approximation of the p ackage power dissipation: p packagediss ?? v rms i rms cos ? (eq 1) where: v rms is the rms voltage from v dd to v out when sourcing current, and from v out to v ss when sinking current. i rms is the rms current flowing in or out of the op-amp and the load. ? is the phase difference between the voltage and the current. for resistive loads, cos ? = 1. figure 21. typical as1710/as1712 single-supply application v rms can be calculated as: v rms ? (v dd - v dc ) + v peak / ? 2( e q 2 ) where: v dc is the dc component of the output voltage. v peak is the highest positive excursion of the ac component of the output voltage. for the circuit shown in figure 21 : v rms = (3.6v - 1.8v) + 1.0v/ ? 2 = 2.507v rms i rms can be calculated as: i rms ? idc + (ipeak/ ? 2) (eq 3) where: i dc is the dc component of the output current. i peak is the highest positive excursion of the ac component of the output current. for the circuit shown in figure 21 : i rms = (1.8v/32 ? ) + (1.0v/32 ? )/ ? 2 = 78.4ma rms therefore, for the circuit in figure 21 the package power dissipation can be calculated as: p packagediss = v rms i rms cos ? = 196mw adding a coupling capacitor improves the package power dissipation because there is no dc current to the load, as shown in figure 22 on page 11 . v in = 2v p-p r + ? r as1710 32? c 3.6v ams ag technical content still valid

www.austriamicrosystems.com/audio/opamps/as1710_12 revision 1.9 13 - 19 as1710/as1712 datasheet - application information 8.6 driving capacitive loads the as1710/as1712 amplifiers have a high tolerance for capacitive loads, and are stable with capacitive loads up to 100pf. figure 26 shows a typical non-inverting capacitive-load driving circuit in the unity-gain configuration. figure 26. capacitive-load driving circuit note: resistor r iso improves the circuit?s phase margin by isolating the load capacitor from the as1710/as1712 output. 8.7 power-up the as1710/as1712 typically settle within 5s after power-up. 8.8 shutdown when shdnn (not included in b versions) is pulled low, supply current drops to 0.5a (per amplifier, v dd = 2.7v), the amplifiers are disabled, and their outputs are driven to v ss . because the outputs are actively driven to v ss in shutdown, any pull-up resistor on the output causes a current drain from the supply. note: pulling shdnn high enables the amplifier. in the as1712 the amplifiers shutdown in pairs. when exiting shutdown, there is a 6s delay before the amplifier output becomes active. 8.9 power supplies and layout the as1710/as1712 can operate from a single 2.7 to 5.5v supply or from dual 1.35 to 2.5v supplies. good design improves devic e performance by decreasing the amount of stray capacitance at the op-amp inputs/outputs. ?? for single-supply operation, bypass the power supply with a 0.1f ceramic capacitor. ?? for dual-supply operation, bypass each supply to ground. ?? decrease stray capacitance by placing external components close to the op-amp pins, minimizing trace and lead lengths. r iso ? + as1710 c f ams ag technical content still valid
