LM2904Q2T

LM2904Q2T is a dual low-power operational amplifier. It packs two op-amps in one package for general analog signal amplification in single- or dual-supply setups. Typical features include a wide supply range (roughly 3–32 V), input common-mode that includes ground, and output swing that approaches ground but is not rail-to-rail on the high side. It’s suited for sensor conditioning, active filters, and simple analog front-ends, especially in automotive/industrial contexts. The “Q2T” suffix indicates an automotive-grade variant (extended temperature) with packaging/tape‑and‑reel options.

Common equivalents for the LM2904Q2T (dual low‑power general‑purpose op‑amp) include: LM2904 (standard), LM358 (similar pinout), Microchip MCP6002/MCP602, TI TLV2372, and precision low‑power OPA23x/OPA2336 series. Always compare supply range, input/output swing, offset, bandwidth and packaging before substituting.

LM2904Q2T features (concise):
- Dual, general-purpose operational amplifiers in one package
- Low power consumption
- Wide supply range: 3 V to 32 V (single supply) or ±1.5 V to ±16 V
- Unity-gain stable; internally compensated (no external cap needed)
- Input common-mode range includes ground; not rail-to-rail on inputs
- Output can swing toward ground but typically cannot reach the positive rail (approx. V+ −1.5 V under load)
- Suitable for single-supply operation and a variety of analog tasks (sensor conditioning, filtering, amplifying)
- Available in 8-pin packages; automotive-grade Q2T variant offers extended temperature range (-40°C to 125°C) and AEC/Q qualification (where applicable)
Note: Exact electricals (offset, bias, bandwidth, slew, rail margins) depend on device family and operating conditions.

LM2904Q2T is a dual low‑power operational amplifier in an 8‑pin package. Pin count: 8. Typical pin functions (standard dual‑op amp pinout, DIP/SOIC):
- Pin 1: OUT A (Output of amplifier A)
- Pin 2: IN− A (Inverting input A)
- Pin 3: IN+ A (Noninverting input A)
- Pin 4: V− (Negative supply / GND in single‑supply use)
- Pin 5: IN+ B (Noninverting input B)
- Pin 6: IN− B (Inverting input B)
- Pin 7: OUT B (Output of amplifier B)
- Pin 8: V+ (Positive supply)
(Exact package outlines vary by manufacturer; verify the datasheet for mechanical pin numbering in specific package variants.)

The LM2904Q2T is manufactured by Texas Instruments (TI). TI is a multinational American semiconductor company that designs and manufactures analog and embedded-processing integrated circuits and other semiconductor devices; it is a major global supplier of chips headquartered in Dallas, Texas.

Typical application areas for LM2904Q2T (a low-power dual op-amp):
- Sensor signal conditioning: thermocouples, RTDs, bridges, strain gauges
- Audio preamplifiers and active filters
- Instrumentation/differential amplification and buffering
- DC servo loops, PID control, motor/actuator drive front ends
- Data-acquisition front ends and precision buffering (voltage followers, summing amps)
- General-purpose, low-power amplifiers in battery-powered, automotive, and industrial electronics

The LM2904Q2T is a dual op‑amp supplied in an 8‑pin VSSOP surface‑mount package (8‑pin SMD), typically shipped on tape‑and‑reel.
