Comparator Type A502

Summary The A502 is a high-speed difference amplifier designed to compare two input voltages and indicate which is more negative. Key specifications include:

• Performance: It features a 1 mV resolution, a switching time of less than 250 nsec, and a maximum common input voltage error of 5 mV over a 20°C temperature range.
• Adjustments: It includes potentiometers for zero set and common balance adjustments.
• Inputs: The input range is 0 to -10V with a maximum current draw of 1 µA.
• Outputs: It produces standard output levels of ground and -3V, capable of supplying up to 5 mA at maximum speed.
• Power Requirements: Operates on +10V (21 mA) and -15V (55 mA) power supplies.
