Maxim Integrated 

High-Precision, Low-Voltage, Current-Sense Amplifier

with Current Output and Chip Select for Multiplexing

ELECTRICAL CHARACTERISTICS (continued)

(VCC = 3.3V, VRS+ = VRS- = 3.0V, VSENSE = 0, VCM = (VRS+ + VRS-)/2, VCS = 3.3V, ROUT = 10kΩ to GND for unidirectional operation,

ROUT = 10kΩ to VCC/2 for bidirectional operation. TA = -40°C to +125°C, unless otherwise noted. Typical values are at TA = +25°C.)

Note 2: All devices are 100% production tested at TA = +25°C. Unless otherwise noted, specifications overtemperature are guaran-

teed by design.

Note 3: Guaranteed by design. Thermocouple, contact resistance, RS- input-bias current, and leakage effects preclude measure-

ment of this parameter during production testing. Devices are screened during production testing to eliminate defective

units.

Note 4: Gain error tested in unidirectional mode: 0.2V ≤ VOUT ≤ 3.1V for the MAX9934T; 0.25V ≤ VOUT ≤ 2.5V for the MAX9934F.
