3 / 21 page  INA200-Q1 INA201-Q1 INA202-Q1 www.ti.com SBOS558 – APRIL 2011 ELECTRICAL CHARACTERISTICS: CURRENT-SHUNT MONITOR Boldface limits apply over the specified temperature range: TA = –40°C to +125°C. At TA = +25°C, VS = +12V, VCM = +12V, VSENSE = 100mV, RL = 10kΩ to GND, RPULL-UP = 5.1kΩ connected from CMPOUT to VS, and CMPIN = GND, unless otherwise noted. INA200-Q1, INA201-Q1, INA202-Q1 CURRENT-SHUNT MONITOR PARAMETERS CONDITIONS MIN TYP MAX UNIT INPUT Full-Scale Sense Input Voltage VSENSE VSENSE = VIN+ – VIN– 0.15 (VS – 0.25)/Gain V Common-Mode Input Range VCM –16 80 V Common-Mode Rejection CMR VIN+ = –16V to +80V 80 100 dB Over Temperature VIN+ = +12V to +80V 100 123 dB Offset Voltage, RTI(1) VOS ±0.5 ±2.5 mV +25 °C to +125°C ±3 mV –40°C to +25°C ±3.5 mV vs Temperature dVOS/dT TMIN to TMAX 5 μV/°C vs Power Supply PSR VOUT = 2V, VIN+ = +18V, 2.7V 2.5 100 μV/V Input Bias Current, VIN– Pin IB ±9 ±16 μA OUTPUT (VSENSE ≥ 20mV) Gain: G INA200-Q1 20 V/V INA201-Q1 50 V/V INA202-Q1 100 V/V Gain Error VSENSE = 20mV to 100mV ±0.2 ±1 % Over Temperature VSENSE = 20mV to 100mV ±2 % Total Output Error(2) VSENSE = 120mV, VS = +16V ±0.75 ±2.2 % Over Temperature VSENSE = 120mV, VS = +16V ±3.5 % Nonlinearity Error(3) VSENSE = 20mV to 100mV ±0.002 % Output Impedance RO 1.5 Ω Maximum Capacitive Load No Sustained Oscillation 10 nF OUTPUT (VSENSE < 20mV) (4) INA200-Q1, INA201-Q1, INA202-Q1 –16V ≤ VCM < 0V 300 mV INA200-Q1 0V ≤ VCM ≤ VS, VS = 5V 0.4 V INA201-Q1 0V ≤ VCM ≤ VS, VS = 5V 1 V INA202-Q1 0V ≤ VCM ≤ VS, VS = 5V 2 V INA200-Q1, INA201-Q1, INA202-Q1 VS < VCM ≤ 80V 300 mV VOLTAGE OUTPUT(5) Output Swing to the Positive Rail VIN– = 11V, VIN+ = 12V (V+) – 0.15 (V+) – 0.25 V Output Swing to GND(6) VIN– = 0V, VIN+ = –0.5V (VGND) + 0.004 (VGND) + 0.05 V FREQUENCY RESPONSE Bandwidth: BW INA200-Q1 CLOAD = 5pF 500 kHz INA201-Q1 CLOAD = 5pF 300 kHz INA202-Q1 CLOAD = 5pF 200 kHz Phase Margin CLOAD < 10nF 40 Degrees Slew Rate SR 1 V/ μs VSENSE = 10mVPP to 100mVPP, Settling Time (1%) 2 μs CLOAD = 5pF NOISE, RTI Voltage Noise Density 40 nV/ √Hz (1) Offset is extrapolated from measurements of the output at 20mV and 100mV VSENSE. (2) Total output error includes effects of gain error and VOS. (3) Linearity is best fit to a straight line.
