The LM324PWR from Texas Instruments is a classic quad general-purpose operational amplifier integrating four independent, high-gain, internally frequency-compensated op amps in a single device. It operates from a total supply voltage of 3V to 30V and supports both single- and split-supply configurations, making it suitable for a wide range of analog signal-conditioning applications.
The LM324 provides a typical gain-bandwidth product of 1.2MHz and a typical slew rate of 0.5V/μs. Maximum input offset voltage at 25°C is 7mV, while typical common-mode rejection ratio is 80dB. Typical input voltage-noise density is approximately 35nV/√Hz at 1kHz.
A key feature of the LM324 is an input common-mode range that includes the negative supply rail, making it especially useful in single-supply circuits processing signals close to ground. The output can also swing close to the negative rail, with approximately 5mV typical low-side output headroom, while typical output-current capability is approximately 40mA.
Typical quiescent current is approximately 0.175mA per channel, and the device uses a bipolar architecture. Common applications include sensor signal conditioning, voltage amplification, active filters, voltage followers, monitoring circuits and other general-purpose analog designs. TI also offers the newer LM324B as a drop-in performance upgrade with improved specifications.
The specific LM324PWR ordering option is supplied in a 14-pin TSSOP (PW) package and operates over a 0°C to +70°C temperature range. It is supplied in 2000-piece large tape-and-reel packaging. The part is RoHS and REACH compliant, uses a NiPdAu lead finish, and carries an MSL 1 / 260°C unlimited floor-life rating. TI currently lists LM324PWR as ACTIVE and available for existing designs.
