LT1213/LT1214 OUUWUAPPLICATIS I FOR ATIOComparator Applications following photos. These amplifiers are unity-gain stable op amps and not fast comparators, therefore, the logic Sometimes it is desirable to use an op amp as a compara- being driven may oscillate due to the long transition time. tor. When operating the LT1213/LT1214 on a single 3.3V The output can be speeded up by adding 20mV or more of or 5V supply, the output interfaces directly with most TTL hysteresis (positive feedback), but the offset is then a and CMOS logic. function of the input direction. The response time of the LT1213/LT1214 is a strong function of the amount of input overdrive as shown in the LT1213 Comparator Response (+)LT1213 Comparator Response (–)20mV, 10mV, 5mV, 2mV Overdrives20mV, 10mV, 5mV, 2mV Overdrives 4 4 2 2 OUTPUT (V) OUTPUT (V) 0 0 100 100 0 0 INPUT (mV) INPUT (mV) 5µs/DIV 5µs/DIV VS = 5V 1213/14 AI01 VS = 5V 1213/14 AI02 RL = ∞ RL = ∞ WWISPLI IF ED SCHE ATIC V + I1 I I I 2 3 4 I I 5 6 C BIAS Q13 M Q14 Q3 Q4 Q15 –IN +IN Q1 Q2 Q11 OUT RF Q7 Q12 CF Q10 Q8 Q16 Q5 Q9 Q6 I7 CO I8 CI V– 1213/14 SS 15
