DESCRIPTION
The LMC7211 is a micropower CMOS comparator available in the space saving SOT23-5 package. This makes
the comparator ideal for space and weight critical designs. The LMC7211 is supplied in two offset voltage
grades, 5 mV and 15 mV.
The main benefits of the Tiny package are most apparent in small portable electronic devices, such as mobile
phones, pagers, notebook computers, personal digital assistants, and PCMCIA cards. The rail-to-rail input
voltage makes the LMC7211 a good choice for sensor interfacing, such as light detector circuits, optical and
magnetic sensors, and alarm and status circuits.
The Tiny Comparator's outside dimensions (length x width x height) of 3.05mm x 3.00mm x 1.43mm allowit to fit
into tight spaces on PC boards.
See the LMC7221 for a comparator with an open-drain output.
FEATURES
●Tiny SOT 23-5 package saves space
●Package is less than 1.43 mm thick
●Guaranteed specs at 2.7V, 5V, 15V supplies
Typical supply current 7 μA at 5V
●Response time of 4 μs at 5V
●Push-pull output
●Input common-mode range beyond V- - and V+
●Low input current
-
Single operational amplifier: The IC contains a single op-amp, making it suitable for amplifying a single
input signal.
-
Low power consumption: The LMC7211 is designed for low power operation, making it suitable for
battery-powered or energy-efficient applications.
-
Low input voltage range: It can operate with a low input voltage range, typically from -0.2V to 0.2V,
allowing for amplification of small input signals.
-
Rail-to-rail input and output: The op-amp offers rail-to-rail input and output voltage ranges, which
means it can handle input signals that extend from the negative supply voltage to the positive supply
voltage, and it can output signals that reach close to the supply voltage rails.
-
Unity-gain stable: The op-amp is unity-gain stable, meaning it can operate with a voltage gain of
1 without external compensation.
-
Low input offset voltage and low input bias current: The LMC7211 exhibits low input offset voltage
and input bias current, providing accuracy and precision in signal amplification.
-
Small package: The LMC7211AIM5X/NOPB is available in a small SOT-23-5 package, which is a
surface mount package with five pins.
-
Wide temperature range: It can operate over a wide temperature range, typically from -40°C to
125°C, ensuring reliable performance in various environmental conditions.
-
ESD protection: The IC incorporates built-in electrostatic discharge (ESD) protection, which
helps to safeguard against damage from static electricity.
