Product details

Quad general-purpose op-amp in 14-SOIC

It delivers a 20 V/µs slew rate and 2.5 MHz gain bandwidth product, drawing 6.2 mA supply current across all four channels.

The 20 V/µs slew rate supports output swings of several volts at frequencies up to a few hundred kilohertz without significant distortion. The 2.5 MHz gain bandwidth product sets the usable closed-loop gain-bandwidth limit: at a gain of 10, the -3 dB bandwidth is about 250 kHz. This is adequate for audio-frequency filtering, motor-current sensing loops, and general-purpose analog processing, but not for video or high-speed data acquisition. The 30 nA input bias current is moderate — fine for low-impedance sources, but high-impedance sensor interfaces may need a FET-input alternative.

Frequently asked questions

What is the LM3900D slew rate and gain bandwidth?

The LM3900D has a slew rate of 20 V/µs and a gain bandwidth product of 2.5 MHz. These ratings define its small-signal frequency response and large-signal settling behavior for general-purpose analog circuits.

What is a direct replacement or alternative for LM3900D?

The LM3900D is a quad general-purpose op-amp. Newer alternatives like the TLV9351IDCKR (single, 3.5 MHz, rail-to-rail) or OPA4374AIPWT (quad CMOS, 6.5 MHz, rail-to-rail) offer improved specs but differ in pinout and supply range — verify pin compatibility and supply voltage before substituting.
