概述

Description

LM2904QDRG4Q1 is the automotive-qualified variant of TI’s LM2904 dual operational amplifier. It contains two low-power op-amps in a single 8-pin package and is designed for analog signal conditioning in automotive and industrial environments.
Key points:
- Dual op-amp, suitable for single-supply operation over a wide voltage range.
- Input common-mode range includes ground; output can swing toward ground under light loads (not rail-to-rail).
- Low power with good temperature performance; robust for automotive use (Q1 indicates automotive grade).
- Typical applications: sensor front ends, active filters, buffering, and various signal-conditioning tasks.
For exact electrical specs (supply range, input/output voltage ranges, gain bandwidth, slew rate, and pinout) and package details, consult the TI datasheet for LM2904QDRG4Q1.

Features

LM2904QDRG4Q1 features (concise):
- Automotive-grade dual operational amplifiers (Q1; AEC-Q100 qualified)
- Single-supply operation across a wide voltage range
- Input common-mode includes ground; output can swing toward ground
- Unity-gain stable; suitable for a variety of configurations
- Low quiescent current (low-power device)
- Broad operating temperature range (industrial/automotive range)
- Short-circuit/overload protection typical for robust operation
- Available in 8-pin packages (e.g., SOIC/DIP variants), RoHS-compliant
Note: for exact electrical specs (gain bandwidth, input offset, max supply, etc.), refer to the datasheet.

Package

It’s an 8-pin surface-mount package (SOIC‑8), RoHS/compliant (lead-free) variant.

Pinout

- Pin count: 8 pins (8-pin package)
- Function: Dual operational amplifier (two op-amps in one package)
Pinout (typical LM2904):
- Pin 1: Output A
- Pin 2: Inverting input A
- Pin 3: Non-inverting input A
- Pin 4: Ground (V−)
- Pin 5: Non-inverting input B
- Pin 6: Inverting input B
- Pin 7: Output B
- Pin 8: Supply (V+)

Manufacturer

Manufacturer: Texas Instruments (TI).
Company type: TI is a multinational semiconductor company that designs and manufactures analog and embedded processing integrated circuits for a wide range of markets (industrial, automotive, consumer, etc.). It is one of the largest global producers of semiconductors.

Application

- General-purpose dual op-amp for signal conditioning and buffering
- Sensor interfaces and conditioning (temperature, pressure, photodiodes)
- Audio preamplification and buffering
- Active filters (low-pass, high-pass, band-pass)
- Voltage followers, summing/difference amplifiers, integrators
- Instrumentation front-ends, servo/control loops, ADC/DAC buffering
- Automotive/industrial control applications (Q1 grade)

Equivalent

Closest equivalents to LM2904QDRG4Q1 (dual, low-power op-amp) are:
- LM358 family (LM358, LM358N, LM358D) – similar 3–32 V single-supply operation.
- LM2904 family in other TI packages (e.g., LM2904N, LM2904IDR) – same device, different packaging.
- For rail-to-rail I/O substitutes (if allowed by specs): LMV358 or TLV237x variants, but verify input/output ranges and supply voltage.
Note: exact drop-in performance depends on your circuit’s input common-mode range and output swing.
