Description

LM2902QPWRQ1 is TI’s quad low-power operational amplifier in the LM2902 family. It contains four independent op-amps on one die, designed for general-purpose analog signal conditioning with low power consumption.
Key points:
- Quad, single-chip solution for multiple amplification stages.
- Suitable for single-supply operation (typical range ~3 V to 32 V); input common-mode includes the negative rail; outputs can swing toward ground but not to the top rail.
- Not rail-to-rail I/O; best for buffering, active filters, sensor conditioning, and other non-rail-to-rail applications.
- Low quiescent current compared with standard op-amps (good for battery-powered and space-limited designs).
- QPWRQ1 suffix indicates a power/automotive-grade style package with extended temperature performance; verify exact ratings in the datasheet for your application.
For precise electrical specs (offset, bias currents, common-mode range, gain, and temperature range), consult the LM2902QPWRQ1 datasheet and packaging options.

Features

Here are concise features of LM2902QPWRQ1:
- Quad operational amplifier in one package
- Wide single-supply voltage: 3 V to 32 V
- Input common-mode range includes the negative rail (ground)
- Output can swing close to ground when sinking current (not rail-to-rail on the high side)
- Unity-gain stable; suitable for various feedback configurations
- Low quiescent current per amplifier (low power consumption)
- Internal protection features (short-circuit/overload tolerant)
- Operating temperature range typically suitable for industrial/automotive applications (variant-dependent)
- Four independent amplifiers per device for compact sensor/interface designs

Package

Application

LM2902QPWRQ1 is a low-power, quad operational amplifier suitable for single- or dual-supply operation. Common applications include: sensor conditioning and interfacing (thermistors, RTDs, pressure/strain sensors); buffering and impedance matching; active filters and integrators; ADC front-ends and signal conditioning; small-signal amplification in automotive/industrial instrumentation; audio preamplifiers in battery-powered devices; general instrumentation for low-power systems.

Equivalent

LM2902QPWRQ1 is a low‑power quad operational amplifier. Common equivalents (quad op-amps with similar specs) include:
- TI LM324 family (quad op-amp)
- Analog Devices AD8604 (rail‑to‑rail quad op-amp)
- Microchip MCP6044 (quad, rail‑to‑rail, low power)
Note: verify supply voltage range, input/output rail behavior, and pinout in datasheets before substituting.
