4 / 24 page www.ti.com Electrical Characteristics Switching Characteristics LM211-EP DIFFERENTIAL COMPARATOR WITH STROBES SLCS140A – DECEMBER 2002 – REVISED MAY 2006 at specified free-air temperatures of Q and M temp ranges, V CC+ = ±15 V (unless otherwise noted) PARAMETER TEST CONDITIONS TA(1) MIN TYP(2) MAX UNIT 25 °C 0.7 3 VIO Input offset voltage(3) mV Full range 4 25 °C 4 10 IIO Input offset current(3) nA Full range 20 25 °C 75 100 IIB Input bias current VO = 1 V to 14 V nA Full range 150 IIL(S) Low-level strobe current(4) V(strobe) = 0.3 V, VID ≤ – 10 mV 25 °C –3 mA Common-mode input 13 to 13.8 to VICR Full range V voltage range –14.5 –14.7 Large-signal differential AVD VO = 5 V to 35 V, RL = 1 kΩ 25 °C 40 200 V/mV voltage amplification I(strobe) = –3 mA, VOH = 35 V, 25 °C 0.2 10 nA High-level (collector) IOH VID = 5 mV output leakage current Full range 0.5 µA IOL = 50 mA, VID = –5 mV 25 °C 0.75 1.5 Low-level (collector-to-emitter) VOL V VCC+ = 4.5 V, VCC– = 0, output voltage Full range 0.23 0.4 IOL = 8 mA, VID = –6 mV ICC+ Supply current from VCC+, output low VID = –10 mV, No load 25 °C 5.1 6 mA ICC– Supply current from VCC–, output high VID = 10 mV, No load 25 °C –4.1 –5 mA (1) Unless otherwise noted, all characteristics are measured with BALANCE and BAL/STRB open and EMIT OUT grounded. Full range is –40 °C to 125°C for Q temp and -55°C to 125°C for M temp. (2) All typical values are at TA = 25°C. (3) The offset voltages and offset currents given are the maximum values required to drive the collector output up to 14 V or down to 1 V with a pullup resistor of 7.5 k Ω to V CC+. These parameters actually define an error band and take into account the worst-case effects of voltage gain and input impedance. (4) The strobe should not be shorted to ground; it should be current driven at –3 mA to –5 mA (see Figure 13 and Figure 27). V CC+ = ±15 V, TA = 25°C PARAMETER TEST CONDITIONS TYP UNIT Response time, low-to-high-level output RC = 500 Ω to 5 V, CL = 5 pF(1) 115 ns Response time, high-to-low-level output RC = 500 Ω to 5 V, CL = 5 pF(1) 165 ns (1) The response time specified is for a 100-mV input step with 5-mV overdrive and is the interval between the input step function and the instant when the output crosses 1.4 V. 4 Submit Documentation Feedback |
