Frequently Asked Questions
What is the supply voltage range and configuration for the LM248DG4?
The LM248DG4 is designed for dual-supply operation with a maximum of ±18V (36V total). It can also operate from a single supply by biasing the non-inverting input appropriately. This wide range supports designs powered from standard ±5V, ±12V, or ±15V analog power supplies commonly used in laboratory instruments, industrial process controllers, and audio equipment.
What is the CMRR specification of the LM248DG4?
The LM248DG4 has a minimum common-mode rejection ratio (CMRR) of 70 dB and a typical CMRR of 90 dB. This high CMRR enables the op-amp to effectively reject common-mode noise and interference signals while amplifying the differential input signal, which is critical in sensor amplification, differential signal processing, and line receiver applications.
How many amplifier channels does the LM248DG4 provide in a single package?
The LM248DG4 contains four independent operational amplifiers (quad op-amp configuration) in a single 14-pin SOIC package. Using four op-amps in one package reduces PCB area and component count compared to using four single-channel amplifiers, and is especially advantageous in multi-channel designs like 4-pole active filters, stereo audio circuits, and quad-channel sensor front-ends.
Is the LM248DG4 frequency compensated and does it require external capacitors?
Yes, the LM248DG4 includes internal frequency compensation, which means it is unity-gain stable without any external compensation capacitors. This simplifies circuit design significantly compared to externally compensated op-amps. The internal compensation ensures stability across a wide range of closed-loop gain configurations, making it straightforward to use in inverting, non-inverting, and differential amplifier topologies.
