3 / 33 page INA226 www.ti.com SBOS547 – JUNE 2011 ELECTRICAL CHARACTERISTICS: VS = +3.3V Boldface limits apply over the specified temperature range, TA = –40°C to +125°C. At TA = +25°C, VIN+ = 12V, VSENSE = (VIN+ – VIN–) = 0mV, VBUS = 12V, unless otherwise noted. INA226 PARAMETER CONDITIONS MIN TYP MAX UNIT INPUT Shunt voltage input range -81.9175 81.92 mV Bus voltage input range(1) 0 36 V Common-mode rejection CMRR VIN+ = 0V to +36V 126 140 dB Shunt offset voltage, RTI(2) VOS ±2.5 ±10 μV vs Temperature 0.02 0.1 μV/°C vs Power supply PSRR VS = +2.7V to +5.5V 2.5 μV/V Bus offset voltage, RTI(2) VOS ±1.25 ±7.5 mV vs Temperature 10 40 μV/°C vs Power supply PSRR 0.5 mV/V Input bias current IIN+, IIN- 10 μA VBUS input impedance 830 k Ω (VIN+ Pin) + (VIN – Pin), Input leakage(3) 0.1 0.5 μA Power-down mode DC ACCURACY ADC native resolution 16 Bits 1 LSB step size Shunt voltage 2.5 μV Bus voltage 1.25 mV Shunt voltage gain error 0.02 0.1 % vs Temperature 10 50 ppm/ °C Bus voltage gain error 0.02 0.1 % vs Temperature 10 50 ppm/ °C Differential nonlinearity ±0.1 LSB ADC conversion time CT bit = 000 140 154 μs CT bit = 001 204 224 μs CT bit = 010 332 365 μs CT bit = 011 588 646 μs CT bit = 100 1.1 1.21 ms CT bit = 101 2.116 2.328 ms CT bit = 110 4.156 4.572 ms CT bit = 111 8.244 9.068 ms SMBus SMBus timeout(4) 28 35 ms DIGITAL INPUT/OUTPUT Input capacitance 3 pF Leakage input current 0 ≤ VIN ≤ VS 0.1 1 μA Input logic levels: VIH 0.7(VS) 6 V VIL –0.5 0.3(VS) V Output logic level VOL SDA, alert IOL = 3mA 0 0.4 V Hysteresis 500 mV (1) While the input range is 36V, the full-scale range of the ADC scaling is 40.96V. See the Basic ADC Functions section. Do not apply more than 36V. (2) RTI = Referred-to-input. (3) Input leakage is positive (current flowing into the pin) for the conditions shown at the top of this table. Negative leakage currents can occur under different input conditions. (4) SMBus timeout in the INA226 resets the interface any time SCL is low for more than 28ms.
