ELECTRICAL CHARACTERISTICS (continued)

(VCC = 3V for MAX4061/MAX4062, VCC = 5V for MAX4060, GND = 0V, SHDN = VCC, INT/AUX = 0V, RG = 11.11kΩ,

RL = 100kΩ to 1.5V, RBIAS = ∞, TA = TMIN to TMAX, unless otherwise noted. Typical values are at TA = +25°C.) (Notes 1, 2)

Note 1: All specifications are 100% tested at TA = +25°C. Specification limits over temperature (TA = TMIN to TMAX) are guaranteed

by design, not production tested.

Note 2: MAX4062 requires a 1µF capacitor from BIAS to ground.
