TCA520B

The TCA520B is designed as a bipolar integrated operational amplifier primarily intended for low-power, low-voltage applications and as a comparator in digital systems.

TCA520B has nine features. (1)Wide supply voltage range. (2)Low supply voltage operation. (3)Low power consumption. (4)Low input bias current. (5)Offset compensation facility. (6)Frequency compensation facility. (7)High slew rate. (8)Large output voltage swing. (9)TTL compatible output. Those are all the main features.

Some absolute maximum ratings of TCA520B have been concluded into several points as follow. (1)Its supply voltage DC would be max 22V. (2)Its input voltage would be from 0V to Vcc. (3)Its differential input voltage would be max 2V. (4)Its power dissipation at Tamb=85°C would be max 200mW. (5)Its storage temperature range would be from -55°C to 125°C. (6)Its operating ambient temperature range would be from -25°C to 85°C. It should be noted that stresses above those listed in absolute maximum ratings may cause permanent damage to device.

Also some electrical characteristics of TCA520B are concluded as follow. (1)Its supply current unloaded would be min 0.5mA and typ 0.8mA and max 1.2mA. (2)Its input voltage would be min 0.9V and max Vcc-0.5V. (3)Its input bias current would be typ 60mA and max 250mA. (4)Its input offset voltage would be typ 1mV and max 6mV. (5)Its variation with temperature would be typ 5uV/K. (6)Its input offset current would be typ 10nA and max 75nA. (7)Its common mode rejection ratio would be min 70dB and typ 100dB. (8)Its input noise voltage at f=1kHz would be typ 15nV. (9)Its input noise current at f=1kHz would be typ 0.4pA. (10)Its input noise angular frequency would be typ 300Hz. (11)Its output current high would be min 100uA and typ 200uA. (12)Its output current low would be min 6mA and typ 12mA. (13)Its output voltage range would be from 0.1V and max Vcc-0.1V. And so on.
