The LM2901DR is a type of comparator, a vital building block for digital circuits. Comparators are used for comparing two voltage values, filtering out unwanted signals, or generating a digital output. The LM2901DR is well-suited for applications such as digital filters, amplified signal detectors, audio signal processing, differential amplifiers, oscillators, and digital switching circuits.
As a comparison device, the LM2901DR functions differently from a traditional amplifier since it compares two input signals and then produces a digital output. It compares two distinct input points, and the output signal is determined by the larger of the two. The LM2901DR’s differential inputs AGND and AGND-L match the common mode range of its own power supply, thus allowing the device to be driven symmetrically about ground.
The LM2901DR includes both a traditional NMOS input stage and a limit comparator that is electrically similar to the comparator module in a typical microprocessor. These two motion detection stages enable the device to detect when two input levels become equal, a process known as hysteresis.
The LM2901DR also features an on-chip hysteresis (OX) switch. This switch controls the amount of input differential necessary to produce a violent transition on the output. This can be used to minimize false detections and reduce instability when the device is operating in noisy environments.
The LM2901DR’s operating power is typically between 9 to 36 volts. It features an operating temperature range between -40 to +85 C and a maximum power dissipation of 100 mW. The device is available in 8-pin DIP, 8-pin SOIC, or 10-pin MSOP packages. The available ICs are also rated for a creepage/clearance distance of 8mm.
The LM2901DR includes two open-drain outputs. The Z output is activated when the two inputs that are to be compared, which are either connected to AGND and AGND-L or to two separate pins, become equal. The output phase is latched. The L output is open-drain and goes low whenever an input difference outside the hysteresis loop is detected. This output has a maximum sink current of 75 mA.
The LM2901DR can provide excellent linearity performance when used with low capacitively-loaded lines. The voltage input range is also low and, as noted above, the device can accurately detect position changes. It can also sustain more than 5V of continuous common-mode input range, helping it to tolerate higher level noise environments.
Overall, the LM2901DR is versatile and flexible and can be used in a wide range of applications. It can be used to detect small position changes and provides excellent linearity performance and high speed switching. Its open-drain outputs also reduce the power and number of gates required for the sense amplifier, making it ideal for portable system applications.
