Parameter Conditions/Comments Min Typ Max Unit VOLTAGE OFFSET Offset Voltage (RTI) TA = 25°C, voltage at –IN decreasing ±1 ±3 mV Over Temperature (RTI) ±2.5 mV Offset Drift 15 µV/°C HYSTERESIS TA = 25°C, voltage at –IN increasing 8 10 12 mV INPUT Input Impedance Differential 2 MΩ Common Mode VS = 5 V to 65 V 5 MΩ Voltage Range Differential Maximum voltage between +IN and –IN 500 mV Common Mode VS – 0.9 VS + 0.2 V Input Bias Current +IN or –IN 12 20 nA OUTPUT Output Current ROUT = 3.3 kΩ, output high 0.8 1 1.2 mA ROUT = 3.3 kΩ, output low 100 nA Rise Time 20% to 80%, ROUT = 3.3 kΩ, VOD = 5 mV, 50 mV step 90 ns 20% to 80%, ROUT = 3.3 kΩ, VOD = >20 mV, 50 mV step 75 ns Fall Time 20% to 80%, ROUT = 3.3 kΩ, VOD = 5 mV, 50 mV step 110 ns 20% to 80%, ROUT = 3.3 kΩ, VOD = >10 mV, 50 mV step 100 ns REGULATOR Nominal Value TA = 25°C, voltage from VREG to VS 2.43 V TA = –40°C to +125°C ±5 % DYNAMIC RESPONSE 50 mV to 250 mV step Propagation Delay1 5 mV ≤ VOD ≤ 15 mV, output low to high 90 ns 15 mV ≤ VOD ≤ 30 mV, output low to high 80 ns VOD ≥ 30 mV, output low to high 75 ns INPUT-REFERRED DYNAMIC ERROR2 15 mV POWER SUPPLY Operating Range Maximum Voltage GND to VS 65 V Minimum Voltage GND to VS 5 V Output Voltage Range3 With respect to VREG 2 62.5 V Supply Current Output low 240 µA Output high 1.2 mA TEMPERATURE RANGE FOR SPECIFIED PERFORMANCE −40 +125 °C 1 VOD represents the overdrive voltage, or the amount of voltage by which the threshold point has been exceeded. 2 See the section. Input-Referred Dynamic Error 3 The voltage at OUT must not be allowed to exceed the VREG voltage, which is always 2.4 V less than the supply. For example, when the supply voltage is 5 V and the output current is 1 mA, the load resistor must not be more than (5 V – 2.4 V)/{1 mA × (1 + 20%)}, or 2.17 kΩ, to ensure the signal does not exceed 2.6 V. As the supply increases, the output signal also can be increased, by the same amount. |
