Description

The LM2902KVQDRQ1 is a Texas Instruments quad operational amplifier in a KVQDRQ1 package. It contains four identical, low-power op-amps in one device, making it ideal for compact, battery-powered or single-supply signal-conditioning applications.
Key points:
- Four op-amps in one package (low power per channel).
- Suitable for general-purpose amplification, buffering, filtering, and sensor conditioning.
- Designed for single-supply operation with input common-mode that includes ground; outputs can swing toward ground under light loading.
- KVQDRQ1 denotes a specific TI package/leadframe variant (check TI for exact pinout, footprint, temperature range, RoHS/tape-and-reel options).
For exact electrical specs (supply voltage range, input/output ranges, offset and bias currents, slew rate) and packaging details, consult the LM2902 datasheet and the TI packaging guide.

Features

Key features of LM2902KVQDRQ1:
- Quad low-power operational amplifiers in a single package.
- Single-supply operation from about 3 V to 32 V.
- Input common-mode range includes ground.
- Output can swing close to ground (not rail-to-rail on the high end).
- Unity-gain stable and suitable for various closed-loop configurations.
- Low input bias current and low input offset voltage.
- Wide operating temperature range (-40°C to +125°C).
- Ideal for battery-powered and general analog applications.
- Available in the KVQDRQ1 package (QFN/compact footprint).

Package

VQFN-14 (Very Thin Quad Flat No-Lead) package.

Pinout

- Pin count: 14 pins
- Function: Quad operational amplifier (four independent op-amps in one package; each with non-inverting and inverting inputs and an output).

Manufacturer

Manufacturer: Texas Instruments (TI).
What kind of company: An American multinational semiconductor company that designs and manufactures analog and embedded processing integrated circuits.

Application

LM2902KVQDRQ1 is a low-power quad op-amp. Suitable for single- or dual-supply analog front-ends. Applications: sensor signal conditioning and buffering (thermistors, photodiodes, strain gauges), active filters (low/high/band-pass), integrator/differentiator stages, ADC input drivers, and general-purpose amplification in battery-powered, automotive, and industrial electronics. The quad package reduces BOM for multi-channel signal chains. Note: not rail-to-rail; verify input common-mode and output swing for your rails.

Equivalent

LM2902KVQDRQ1 is a low‑power quad op‑amp. Common equivalents (pinout/specs may vary) include:
- NJM2902 (New Japan Radio)
- MC33072 / MC33074 (ON Semiconductor/Motorola)
Also, the LM324 family (quad op‑amps) is often used as a substitute in many single‑supply designs. Always check data sheets for pinout, input common‑mode range, and output swing before substituting.
