ELECTRICAL CHARACTERISTICS — TA = TMIN to TMAX (continued)

(VCC = +1.8V to +5.5V, VEE = 0, VCM = 0, VOUT = VCC / 2, RL = 100kΩ tied to VCC / 2, SHDN = VCC, TA = TMIN to TMAX, unless oth-

erwise noted.) (Note 1)

Note 1: The MAX4240EUK, MAX4241EUA, MAX4242EUA, and MAX4243EUB specifications are 100% tested at TA = +25°C. All

temperature limits are guaranteed by design.

Note 2: Shutdown mode applies to the MAX4241/MAX4243 only.

Note 3: Input bias current and input offset current are tested with VCC = +5.0V and 0 ≤ VCM ≤ 5.0V.

Note 4: Tested over the specified input common-mode range.

Note 5: Tested for 0 ≤ VOUT ≤ VCC. Does not include current through external feedback network.

Note 6: Channel-to-channel isolation specification applies to the MAX4242/MAX4243/MAX4244 only.
