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 = 1F.
