Note 1: Continuous power dissipation must also be observed.

Note 2: This device is constructed using a unique set of packaging techniques that impose a limit on the thermal profile the device

can be exposed to during board-level solder attach and rework. This limit permits only the use of the solder profiles recom-

mended in the industry-standard specification, JEDEC 020A, paragraph 7.6, Table 3 for IR/VPR and convection reflow.

Preheating is required. Hand or wave soldering is not allowed.

Note 3: All specifications are 100% tested at TA = +25°C; temperature limits are guaranteed by design.

Note 4: Quiescent power-supply current is specified and tested with no load on the outputs. Quiescent power-supply current

depends on the offset voltage when a practical load is connected to the amplifier.

Note 5: Common-mode bias voltage is the voltage on BIAS and is nominally VCC/2.

Note 6: Differential voltage gain for the MAX4366 is specified as an open-loop parameter because external resistors are used to set

the closed-loop gain. The MAX4367/MAX4368 contain internal feedback resistors that preset the differential voltage gain.

Differential voltage gain is defined as (VOUT+ - VOUT-) / (VIN - VBIAS). All gains are specified over an output voltage range of

0.6V

≤ VOUT ≤ 4.4V.

Note 7: Specification applies to either output. An amplifier peak output current of 87mA is required to support an output load power

of 60mW for a 16

Ω load, or 120mW for a 32Ω load.

Note 8: Output power specifications are inferred from the output current test. For 60mW into a 16

Ω load, IOUT(PEAK) is 87mA and

VOUT(P-P) is 1.39V per amplifier. For 120mW into a 32Ω load, IOUT(PEAK) is 87mA and VOUT(P-P) is 2.77V per amplifier.

Note 9: Guaranteed by design. Not production tested.

Note 10: Measurement bandwidth for THD+N is 20Hz to 20kHz.

Note 11: Power-up and shutdown times are for the output to reach 90% of full scale with CBIAS = 1µF.
