Description

LM2904QPWRQ1 is TI’s RoHS-compliant variant of the LM2904, a dual general‑purpose operational amplifier in an 8‑pin package. It provides two low‑power, high‑gain op amps suitable for single‑ or dual‑supply operation. Key features include low quiescent current per amplifier, a wide supply voltage range, input common‑mode range that includes ground, and outputs that can swing toward ground under light loading. Applications run from analog signal conditioning and sensing to filtering and small‑signal amplification in automotive, consumer, and industrial circuits. The QPWRQ1 suffix denotes a specific package/lead finish variant (RoHS compliant); packaging details vary by vendor. Note: it is not intended as a comparator. For exact electrical specs, pinout, and packaging details, consult the TI LM2904QPWRQ1 datasheet.

Features

Here are the key features of LM2904QPWRQ1:
- Dual, general-purpose operational amplifiers
- Wide supply voltage: 3 V to 32 V
- Input common-mode range includes the negative rail (ground)
- Output can swing close to ground (rail-to-ground for sinking current near 0 V)
- Unity-gain stable for closed-loop configurations
- Low power consumption per amplifier
- Suitable for a wide temperature range (-40°C to 125°C)
- High gain/bandwidth suitable for sensor conditioning and general amplification
- Thermally enhanced PowerPAD (QPWRQ1) package for improved heat dissipation and higher power handling
Note: Specific numbers (offset, bias current, GBP) are device-dependent; consult the datasheet for exact figures.

Package

8‑pin surface‑mount package; PowerPAD/HTSSOP‑8 style (PWRQ1 RoHS variant).

Pinout

- Pin count: 8 pins (8-pin package)
- Function: Dual low-power operational amplifier (two independent op-amps in one package). Pinout: A: non-inverting input pin 3, inverting input pin 2, output pin 1; B: non-inverting input pin 5, inverting input pin 6, output pin 7; power pins: V+ pin 8, V− pin 4.

Manufacturer

- Manufacturer: Texas Instruments (TI)
- Company type: American multinational semiconductor company that designs and manufactures analog and mixed-signal integrated circuits; it acquired National Semiconductor, the original LM2904 designer.

Application

LM2904QPWRQ1 is a low-power dual operational amplifier. Common application areas include:
- Sensor signal conditioning (bridge sensors, thermistors, RTDs, photodiodes)
- Instrumentation front-ends and data-acquisition conditioning
- Active filters, integrators, transimpedance and peak detector circuits
- Servo/feedback control loops (motor control, power-supply regulation)
- Audio/low-noise preamplification in consumer and automotive electronics
- General-purpose low-power op-amp needs in automotive/industrial environments

Equivalent

LM2904QPWRQ1 is a low-power dual op-amp. Equivalents include:
- LM358/LM358P (TI) – closest drop-in
- NJM2904 (New Japan Radio)
- NTE2904 (NTE cross-reference)
- KA2904 (Renesas/NEC)
