MPQ8112/MPQ8112A – 60V, HIGH-SIDE, CURRENT-SENSE AMPLIFIER

ELECTRICAL CHARACTERISTICS

V_CC= 12V, V_RG1= 12V, T_A= -40°C to +125°C, typical values at T_J= 25°C. R_G1= R_G2= 0Ω, and R_OUT

not used for the MPQ8112. R_G1= R_G2= 1kΩ, and R_OUT= 10kΩ for the MPQ8112A. All unless

otherwise noted.

Notes:

6) CMR = 20 x log[(V_CM1- V_CM2) / (V_OUT1- V_OUT2)]. V_OUT1is the output voltage at V_CM1, and V_OUT2is the output voltage at V_CM2

7) V_OS= V_SENSE1- V_OUT1/ [(V_OUT1- V_OUT2) / (V_SENSE1- V_SENSE2)]. V_OUT1is the output voltage at V_SENSE1, and V_OUT2is the output voltage at V_SENSE2

8) Not tested in production. Guaranteed by design and characterization.

9) PSRR = 20 x log[(V_CC1- V_CC2) / (V_OUT1- V_OUT2)]. V_OUT1is the output voltage at V_CC1, and V_OUT2is the output voltage at V_CC2
