Most of operational amplifiers are not suited for comparator use because of low transition speed, output signal incompatible with standard logics level and mainly, phase inversion. The phase inversion occures when a strong differential signal is applied to the device inputs. The output level is then inverted and shows a wrong logic state. TSH22 does not present this problematic behaviour. Displayed curves below show the device response in standard comparator configuration without external components. Transition speed : Typical transition speed under a single 5V supply voltage is about 2µs from 50mV overdrive. VOH min. is 3.7V and V OL max. is 0.2V (2kΩ load) making it compatible with standard logic families. Figures 3 & 4 show output signal transition for a 50mV and 250mV input signal overdrive respectively of 3µs and 1µs.

Figure 5 : Behaviour with TSH22 Figure 6 : Saturation behaviour with 15MHz standard operational amplifier Input & Ouput Voltages, Vid (V), Vo (V) At high differential input voltage, the TSH22 keeps the right output level thanks to its specific input structures. The advantage is obvious on the following figures and can be also an advantage in linear use when saturation might occure. 6/11 8 Vid 6 4 2 0 -2 -4 Vo -6 -8 Time (50µs/div) TSH22 INPUT OFFSET VOLTAGE DRIFT VERSUS TEMPERATURE SUPPLY CURRENT VERSUS SUPPLY VOLTAGE (BOTH OP-AMPS) 0.4 Input Offset Voltage, Vio (mV) 0.3 0.2 0.1 0 -0.1 -0.2 -0.3 -0.4 -50 -25 0 25 50 75 100 125 Temperature, Tamb (˚C) SINK CURRENT SOURCE CURRENT Output Sink Current, Isink (mA) 50 45 40 35 30 25 20 15 Tamb = 25˚C Vcc = ±15V Vid = 1V 10 5 0 -15 -12 -9 -6 -3 0 3 6 Applied Output Voltage, Vo (V) 9 12 SLEW RATE @ 30V 15 SLEW RATE @ 3V 20 0.8 Output Voltage, Vo (V) 10 5 0 -5 -10 -15 Tamb = 25˚C Vcc = +2V/-1V Av = +1 RL = 2kΩ CL = 100pF 0.6 Output Voltage, Vo (V) Tamb = 25˚C Vcc = ±15V Av = +1 RL = 2kΩ CL = 100pF 15 0.4 0.2 0 -0.2 -0.4 -0.6 -20 Time (0.5µs/div) -0.8 Time (0.2µs/div) 7/11 TSH22 LARGE SIGNAL VOLTAGE GAIN @NO LOAD LARGE SIGNAL VOLTAGE GAIN @ LOAD 20 Output Voltage, Vo (V) 15 10 5 0 -5 Tamb = 25˚C Vcc = ±15V No Load -10 -15 -20 -0.4 -0.3 -0.2 -0.1 0 0.1 0.2 0.3 0.4 Differential Input Voltage, Vid (mV) SMALL SIGNAL RESPONSE @ 30V SMALL SIGNAL RESPONSE @ 3V UNITY GAIN BANDWITH @ 30V UNITY GAIN BANDWITH @ 3V 45 Tamb = 25˚C Vcc = +2V/-1V AVCL = 100 RL = 2kΩ CL = 100pF 35 Voltage Gain (dB) 30 0 30 25 Gain 20 60 15 90 120 10 Phase 5 150 0 180 -5 10k 100k 1M Frequency, F (Hz) 8/11 10M Phase (degrees) 40 TSH22 CLOSED LOOP BANDWITH @ 30V CLOSED LOOP BANDWITH @ 3V 21 21 18 15 AVCL = +5 15 9 AVCL = +2 6 3 9 AVCL = +2 6 3 AVCL = +1 0 -3 -3 -6 -6 -9 Tamb = 25˚C Vcc = +2V/-1V AVCL = 5,2,1 RL = 2kΩ CL = 100pF AVCL = +5 12 Voltage Gain (dB) Voltage Gain (dB) 12 0 18 Tamb = 25˚C Vcc = ±15V AVCL = 5,2,1 RL = 2kΩ CL = 100pF AVCL = +1 -9 100k 1M Frequency, F (Hz) 10M 100k 1M Frequency, F (Hz) 10M 9/11 TSH22 PACKAGE MECHANICAL DATA 8 PINS - PLASTIC DIP Millimeters Inches Dim.
