概述

Description

LM2904LVIDGKR is TI’s low‑power, dual operational amplifier in an 8‑pin package. It contains two independent op‑amps suitable for general‑purpose analog amplification in single‑ or dual‑supply designs.
Key points:
- Dual op‑amp, non‑inverting and inverting inputs per amplifier, with outputs for each channel.
- Not rail‑to‑rail: input common‑mode can include ground on a single supply; outputs don’t swing to the positive rail.
- Typical supply range supports single‑supply operation (roughly 3 V to about 30–32 V) and dual supplies.
- Low power suitable for battery‑powered and compact analog circuits (audio preamps, sensor conditioning, filters, instrumentation signals, etc.).
- Packaging code LVIDGKR indicates the specific RoHS/lead‑free variant and footprint (exact package type and temperature range shown in the datasheet).
For precise electrical specs (offset, bias, gain‑bandwidth, exact pinout, and packaging), consult the LM2904LIDGKR datasheet from TI.

Features

Key features of LM2904LVIDGKR (dual op-amp):
- Dual general-purpose operational amplifiers in a single package.
- Low-power bipolar design; suitable for battery-powered/smart applications.
- Wide supply range: 3 V to 32 V on a single supply (or ±1.5 V to ±16 V).
- Input common-mode range includes ground; outputs can swing close to ground.
- Not rail-to-rail on the top rail; output typically about 1.5 V below Vcc.
- Unity-gain stable and suitable for filters, buffers, amplifiers, and integrators.
- Moderate gain bandwidth and slew rate suitable for general analog tasks (industrial temperature range).
- Short-circuit protection and current limiting on outputs.
- Temperature range: -40°C to +125°C (industrial/high-temperature tolerance).
- Pb-free/RoHS-compliant packaging (LVIDGKR) in common 8-pin packages (DIP/SOIC/MSOP variants).
Note: Exact electrical numbers (offset, bias current, GBW, etc.) vary by device lot and temperature; refer to the datasheet for precise specs.

Package

An 8-pin VSSOP (Very‑Small‑Outline) package, RoHS lead-free variant.

Manufacturer

Manufacturer: Texas Instruments (TI).
Company type: American multinational technology company that designs and manufactures semiconductors and analog/mixed-signal integrated circuits; one of the world’s largest semiconductor companies.

Application

Typical applications for LM2904LVIDGKR (dual low-power op-amp):
- Battery-powered sensor interfaces and signal conditioning
- Sensor front-ends (thermistors, RTDs, photodiodes, MEMS)
- Active filters, integrators, and oscillators
- DC control loops, servo amplifiers, and instrumentation preamps
- Audio preamps and other low-noise signal amplification
- General-purpose analog front ends in consumer/industrial electronics
Note: not rail-to-rail; ensure proper supply and headroom for your signal.

Equivalent

Equivalent products (cross-reference for LM2904LVIDGKR):
- LM358 / LM358N (dual low-power op-amp; pin-compatible substitute)
- LMV358 (rail-to-rail input/output version for lower-voltage needs)
- Other LM2904-family variants in TI’s catalog may be cross-referenced as appropriate
Note: verify voltage range and rail-to-rail needs for your design, but LM358 is the standard drop-in substitute.
