(1) Audio amplifiers, having a maximum rated continuous power output of 50 W or less at an ambient temperature of 298K (25°C);

Note:

For audio amplifiers, the 358K (85°C) upper temperature limit specified in (d)(2)(B) above is not applicable. The lower limit of 233K (-40°C) is applicable.

(2) Instrumentation amplifiers, having all of the following characteristics:

(A) A best-case rated linearity of no better than ±0.01 per cent at a gain of 100;

(B) A maximum gain-bandwidth product of no more than 7.5 expressed in MHz (e.g. a maximum bandwidth of 75 kHz at 3dB and a gain of 100); and

(C) A typical slew rate at unity-gain not exceeding 3 V/microsecond;

(3) Isolation amplifiers;

(4) Operational amplifiers, having all of the following characteristics:

(A) A typical unity-gain open-loop bandwidth of no more than 5 MHz;

(B) A typical open-loop voltage gain of no more than 105, i.e. 100 dB;

(C) Either:

(a) A maximum intrinsic rated input offset voltage of no less than 1.0 mV; or

(b) A maximum input offset voltage drift of no less than 5 microvolt/K;

(D) A typical slew rate at unity-gain not exceeding 6 V/microsecond; and

(E) A typical power dissipation of more than 10 mW per amplifier, if the typical slew rate at unity-gain exceeds 2.5V/microsecond; or

(5) Untuned alternating current (AC) amplifiers, having both of the following characteristics;

(A) A bandwidth of less than 3 MHz; and

(B) A maximum rated power dissipation of 5 W or less at an ambient temperature of 298K (25°C);

(1) Analogue multiplier or divider "monolithic integrated circuits", "multichip integrated circuits", "film type integrated circuits" or "hybrid integrated circuits", having both of the following characteristics:

(1) A best-case rated linearity of no better than ±0.5 per cent of full scale; and

(2) A -3 dB small signal bandwidth of no more than 1 MHz,

(m) Converter "monolithic integrated circuits", "multichip integrated circuits", "film type integrated circuits" or "hybrid integrated circuits", as follows:

(1) Analogue-to-digital converters, having both of the following characteristics:

(A) A maximum conversion rate to rated accuracy of no more than 50,000 complete conversions per second, i.e. a conversion time to maximum resolution of no less than 20 microsecond; and
