3 DESCRIPTIONSThe LM2901 is the quad comparators version, and theoutputs can be connected to other open-collector
outputs to achieve wired-AND relationships. It canoperate from 3.3V to 32V, and have low power
consuming 45µA (TYP) per channel.
The LM2901 consist of four independent voltage
comparators that are designed to operate from a single
power supply over a wide range of voltages. Quiescentcurrent is independent of the supply voltage. The device
is the most cost-effective solutions for applications
where low offset voltage, high supply voltage capability,
low supply current, and space saving are the primary
specifications in circuit design for portable consumer
products.
The LM2901 is available in Green SOIC-14, TSSOP-14
packages. It operates over an ambient temperature
range of -40°C to +125°C.

(1) Stresses above these ratings may cause permanent damage. Exposure to absolute maximum conditions for extended periods may
degrade device reliability. These are stress ratings only, and functional operation of the device at these or any other conditions beyond
those specified is not implied.
(2) Input terminals are diode-clamped to the power-supply rails. Input signals that can swing more than 0.3V beyond the supply rails should
be current-limited to 10mA or less.
(3) Output terminals are diode-clamped to the power-supply rails. Output signals that can swing more than 0.3V beyond the supply rails
should be current-limited to ±55mA or less.
(4) Short-circuit from output to VCC can cause excessive heating and eventual destruction.
(5) The maximum power dissipation is a function of TJ(MAX), RθJA, and TA. The maximum allowable power dissipation at any ambient
temperature is PD = (T J(MAX) - TA) / RθJA. All numbers apply for packages soldered directly onto a PCB.

8 Detailed Description
8.1 Overview
The LM2901 family of comparators can operate up to 32V on the supply pin. This standard device has provenubiquity and versatility across a wide range of applications. This is due to its low power and high speed. The
open-drain output allows the user to configure the output's logic low voltage (VOL) and can be utilized to enable
the comparator to be used in AND functionality.

9 Application and Implementation
Information in the following applications sections is not part of the RUNIC component specification, and RUNIC
does not warrant its accuracy or completeness. RUNIC’s customers are responsible for determining suitabilityof components for their purposes. Customers should validate and test their design implementation to confirm
system functionality.

9.1 Application Information
LM2901 is typically used to compare a single signal to a reference or two signals against each other. Many
users take advantage of the open drain output (logic high with pull-up) to drive the comparison logic output to alogic voltage level to an MCU or logic device. The wide supply range and high voltage capability makes thiscomparator optimal for level shifting to a higher or lower voltage.

Figure 8. Single-Ended and Differential Comparator Configurations

9.3 Detailed Design Procedure
When using the device in a general comparator application, determine the following:• Input Voltage Range• Minimum Overdrive Voltage• Output and Drive Current• Response Time

9.4 Input Voltage Range
When choosing the input voltage range, the input common mode voltage range (VICR) must be taken in toaccount. If temperature operation is below 25°C the VICR can range from 0 V to VCC– 2.0 V. This limits the input
voltage range to as high as VCC– 2.0 V and as low as 0 V. Operation outside of this range can yield incorrectcomparisons.

LM2901
10 Layout10.1 Layout Guidelines
For accurate comparator applications without hysteresis, it is important maintain a stable power supply withminimized noise and glitches. To achieve this, it is best to add a bypass capacitor between the supply voltage
and ground. This should be implemented on the positive power supply and negative supply (if available). If a
negative supply is not being used, do not put a capacitor between the IC's GND pin and system ground.
Minimize coupling between outputs and inverting inputs to prevent output oscillations. Do not run output andinverting input traces in parallel unless there is a VCC or GND trace between output and inverting input traces
to reduce coupling. When series resistance is added to inputs, place resistor close to the device.
