What are the key features of LM324ADBRE4?
- Four independent voltage-feedback op-amps in one SSOP-14 package reduces board space by up to 75% versus discrete single-channel solutions
- 65 dB minimum CMRR (80 dB typical) with 200 nA maximum input bias current enables accurate differential signal conditioning in sensor interfaces
- Single-supply operation from 3 V to 32 V or dual-supply ±1.5 V to ±16 V supports diverse power architectures from battery to industrial rail
What is LM324ADBRE4 used for?
The LM324ADBRE4 is widely used in industrial control panels, automotive body electronics, and consumer appliances for buffering, summing, and comparing analog sensor signals. Its four channels in one package efficiently replace discrete single-channel amplifiers in multi-channel transducer conditioning circuits, active filters, and comparator stages where supply voltage can range from 3 V to 32 V single-supply.

Frequently Asked Questions
How does the input bias current of LM324ADBRE4 affect precision in high-impedance sensor interfaces?
The LM324ADBRE4 has a maximum input bias current of 200 nA at 25°C and 100 nA typical. At a source impedance of 100 kΩ, this bias current creates a 10 mV to 20 mV systematic input offset error, which must be compensated by matching source impedances at the two inputs or adding a series resistor to the non-inverting input. For sub-millivolt precision, a lower-bias part such as a JFET-input amplifier with less than 10 pA bias current is a better alternative.
What supply voltage configurations does LM324ADBRE4 support, and does it operate from 5 V single-supply?
LM324ADBRE4 operates from a single supply of 3 V to 32 V or a split supply of ±1.5 V to ±16 V. At 5 V single-supply, the output swings from approximately 10 mV above ground to about 1.5 V below VCC, which limits usable output range to roughly 0 V to 3.5 V. This near-ground output swing makes it suitable for signal conditioning circuits that need to interface with 5 V ADC inputs without level-shifting circuitry.
How does the SSOP-14 package of LM324ADBRE4 compare to the SOIC-14 footprint for board space savings?
The SSOP-14 package occupies approximately 5.3 mm x 3.9 mm versus the SOIC-14 footprint of about 8.7 mm x 3.9 mm, saving roughly 40% of PCB area in the package footprint alone. This size reduction matters in densely populated analog front-end boards where four op-amp channels must fit alongside ADC, reference, and filter components within a constrained keep-out zone.
When is LM324ADBRE4 a cost-effective alternative to precision op-amps in multi-channel comparator circuits?
LM324ADBRE4 fits comparator circuits where the threshold accuracy requirement is above ±5 mV, since its 5000 µV maximum input offset voltage limits precision. For window comparators, voltage divider monitoring, and open-collector logic threshold detection at 65 dB CMRR with 4 channels sharing one 14-pin package, the LM324ADBRE4 is significantly lower cost than four separate precision op-amps with submillivolt offsets, and its internal frequency compensation eliminates the external capacitors needed by uncompensated amplifiers.
