What are the key features of PLM2904BIDR?
- 1.2 MHz gain-bandwidth product enabling audio-frequency and signal conditioning amplifier designs
- 96 dB common-mode rejection ratio reducing power-supply noise and ground-loop interference
- Single-supply operation from 3 V to 32 V and dual-supply from ±1.5 V to ±16 V
- Pin-compatible LM2904 drop-in replacement qualified over -40 °C to +125 °C industrial temperature range
What is PLM2904BIDR used for?
PLM2904BIDR is used in industrial sensor signal conditioning, 4 to 20 mA current-loop receivers, and comparator circuits that must operate over wide supply voltages without a split rail. Its single-supply input range extending down to the negative rail makes it ideal for low-side current sensing and ground-referenced transducer amplification in motor drives and HVAC controllers. Designers also use it in audio preamplifier stages and active filter networks in consumer electronics where LM2904 form-factor compatibility simplifies second-source substitution.

Frequently Asked Questions
How does the 96 dB CMRR of PLM2904BIDR benefit industrial 4 to 20 mA loop designs?
In a 4 to 20 mA current-loop receiver circuit, common-mode voltages from ground potential differences between the field sensor and controller can reach several volts. PLM2904BIDR's 96 dB common-mode rejection ratio attenuates a 1 V common-mode disturbance to approximately 16 µV at the differential output, well below the 4 mV full-scale LSB of a 12-bit ADC sampling the loop signal, preserving measurement accuracy across long cable runs.
What gain-bandwidth product does PLM2904BIDR offer, and how does it affect closed-loop bandwidth at a gain of 100?
PLM2904BIDR has a 1.2 MHz gain-bandwidth product. At a closed-loop gain of 100 V/V (40 dB), the usable signal bandwidth is approximately 1.2 MHz / 100 = 12 kHz, which covers the full audio spectrum up to 10 kHz for microphone preamplifier and audio signal conditioning applications operating from a single 5 V supply.
Can PLM2904BIDR directly replace an existing LM2904 in a PCB without layout changes?
Yes, PLM2904BIDR is pin-compatible with the industry-standard LM2904 dual op-amp in the 8-pin SOIC (SOIC-8) package, allowing a drop-in substitution without PCB modifications. The PLM2904B variant offers the same single-supply 3 V to 32 V operating range and extends the temperature rating to -40 °C to +125 °C, which is broader than some commercial-grade LM2904 alternatives limited to 0 °C to +70 °C.
For a battery-powered sensor node, how low can PLM2904BIDR's supply voltage go while maintaining specification?
PLM2904BIDR operates from a single supply as low as 3 V, making it compatible with a single lithium coin cell at 3 V or two series alkaline cells at approximately 3 V nominal. The input common-mode range extends down to the negative supply rail, enabling the amplifier to process 0 V to 1 V sensor output signals directly without an additional bias resistor network when running from a 3.3 V microcontroller supply.
