Comparators

Comparators provide the best transition between the equivalent and digital domains, and comparators are the best circuits. When testing two input lines, the comparator’s digital output is high or low depending on whether one input is higher or lower than the other. A comparator is a device that compares two voltages or currents and outputs a digital signal, which shows which is greater. The comparator’s output value indicates which input is greater or lesser. The comparator compares the two references and displays the result of the comparison. It has two correlated input terminals and a binary digital output.
Sourcewell is an authorized distributor of comparators in India. All comparator products are available in bulk quantities at the best prices here. We also provide sample support and immediate delivery of the products.

NE555

The NE555 is a CMOS RC timer that offers improved performance over standard SE/NE555 and 355 timers and is a direct replacement for devices used in most applications. Improved parameters such as low current source, wide operation, low threshold, trigger and reset current, no short current supply during time, flexible, more efficient, and stable operation without voltage control.
Attribute

Low Supply Current
Wide operation supply voltage range – 2V to 18V
Operates in both astable and monostable modes.

TJ339

The TJ339 has four independent voltage comparators. It has been specifically designed to operate from a single source of electricity over a wide range. It is also possible to operate with separate power supplies, and the low current sources are independent of the size of the power supplies. The output can be connected to another open output for wired AND connection.
Attribute

Low supply current drain independent of the supply voltage
Low input biasing current
Low input offset current
Low output saturation voltage

LM339

The LM339 has four independent voltage comparators. It has been specifically designed to operate from a single source of electricity over a wide range.
