Overview

Description

The LM2904Q2T is TI’s automotive-grade dual operational amplifier (two op-amps in one 8-pin package). It’s designed for low power and general-purpose amplification in harsh environments. Key points:
- Two independent op-amps in one package (DIP-8/SO-8).
- Wide supply range: typically 3 V to 32 V (single or dual supply).
- Input common-mode range includes ground; output can swing toward ground on a single supply.
- Automotive qualification: extended temperature range (commonly −40 °C to +125 °C).
- Features low input bias current and adequate bandwidth for sensor conditioning, active filters, and ADC front-ends.
- Not a comparator; use a dedicated comparator if you need open-loop behavior.
In short, it’s a rugged, dual, general-purpose op-amp suited for automotive sensing and conditioning applications.

Features

Here are the key features of LM2904Q2T:
- Dual general-purpose operational amplifiers
- Automotive-qualified: AEC-Q100 Grade 2
- Temperature range: -40°C to 125°C
- Wide supply voltage: 3 V to 32 V (single) or ±1.5 V to ±16 V
- Input common-mode range includes ground
- Output can swing close to ground; not rail-to-rail at the high end
- Unity-gain stable; internally compensated
- Low quiescent current; suitable for battery-powered applications
- Two amplifiers per package
- Available in standard 8-pin packages (with Tape & Reel option)

Package

8-pin surface-mount package (SOIC-8).

Pinout

- Pin count: 8 pins (8-pin package, e.g., SOIC/DIP).
- Function: Dual low-power operational amplifier (two independent op-amps in one package).
- Typical pinout (reference): 1 = Output A, 2 = Inverting input A, 3 = Non-inverting input A, 4 = V−, 5 = Non-inverting input B, 6 = Inverting input B, 7 = Output B, 8 = V+.

Manufacturer

- Manufacturer: STMicroelectronics (ST)
- What kind of company: STMicroelectronics is a European multinational semiconductor company that designs and manufactures a wide range of integrated circuits and electronic components (analog, MEMS, microcontrollers, sensors, power management), headquartered in Geneva, Switzerland.

Application

- Sensor signal conditioning and buffering
- Audio preamplification
- Active filters (low/high/band-pass)
- Instrumentation front-end for ADCs (differential buffering)
- Control loops and servo/regulator feedback
- Transimpedance/photodiode amplifiers

Equivalent

LM2904Q2T is a low-power dual op-amp (single-supply). Practical equivalents include:
- LM358 / LM358N (dual op-amp, similar specs)
- LMV358 (rail-to-rail I/O, TI)
- TLV2372 (dual, rail-to-rail)
- MCP6002 (Microchip, dual, RRIO)
- MC33072 (dual op-amp, similar performance)
Note: pinouts differ; verify datasheets for footprint and performance when substituting.
