Differential Microphone Preamplifier with

Internal Bias and Complete Shutdown

ELECTRICAL CHARACTERISTICS (continued)

(VCC = 3V, GND = 0V, SHDN = VCC, INT/AUX = 0V, RG = 11.11kΩ, RL = 100kΩ to 1.5V, RBIAS = ∞, VOUT is measured between OUT

and OUT. TA = TMIN to TMAX, unless otherwise noted. Typical values are at TA = +25°C.) (Notes 1 and 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: MAX4063 requires a 1µF capacitor from BIAS to ground and a 10pF capacitor from ADJ to OUT.
