Note 1: MAX4174/MAX4175/MAX4281 and MAX4274/MAX4275/MAX4282 and MAX4284 are 100% production tested at
TA = +25°C. All temperature limits are guaranteed by design.
Note 2: Guaranteed by design.
Note 3: The input common-mode range for IN_+ is guaranteed by a functional test. A similar test is done on the IN_- input. See the
Applications Information section for more information on the input voltage range of the GainAmp.
Note 4: For AV = -0.5V/V and AV = -0.25V/V, the output voltage swing is limited by the input voltage range.
Note 5: Includes noise from on-chip resistors.
Note 6: The gain accuracy test is performed with the GainAmp in noninverting configuration. The output voltage swing is limited by
the input voltage range for certain gains and supply voltage conditions. For situations where the output voltage swing is lim-
ited by the valid input range, the output limits are adjusted accordingly.
Typical Operating Characteristics
(VCC = +5V, RL = 100kΩ to VCC / 2, small-signal VOUT = 100mVp-p, large-signal VOUT = 1Vp-p, TA = +25°C, unless otherwise noted.)
