概述

Description

Introduction to LMV324QDR (TI)
- A Texas Instruments quad operational amplifier in a single package, part of the LMV324 family.
- Low-voltage, rail-to-rail input and output (RRIO) performance ideal for battery-powered or portable circuits.
- Four op-amps share one supply, making it compact for sensor conditioning, active filters, and small signal processing.
- Key traits: low bias currents, low offset, unity-gain stability, and good noise performance for low-power applications.
- Typical supply range (low-voltage family): around 1.8 V to 5.5 V.
- Packaging suffix (QDR) denotes RoHS-compliant packaging options; check the datasheet for exact package type (e.g., MSOP-14, TSSOP-14, etc.) and ordering details.
- Common uses: sensor interfaces, instrumentation, DAC/ADC front-ends, audio preamps, and general signal conditioning in compact designs.
Note: For precise electrical specs (offset, bias current, GBW, input range, output swing) and exact package options, refer to the latest TI datasheet for LMV324QDR.

Features

Here are the key features of LMV324QDR (quad op-amp):
- Quad operational amplifiers in a single package
- Rail-to-rail input and rail-to-rail output on all four amps
- Single-supply operation from about 2.7 V to 5.5 V
- Unity-gain stable (suitable for voltage followers and filters)
- Low input bias current and low input offset voltage
- Low quiescent current per amplifier (battery-powered, low-power designs)
- Wide use in sensor front-ends, signal conditioning, and audio applications
- Available in compact TI packages (e.g., 14-pin VSSOP/SOIC variants) under the QDR suffix
Note: Details like exact temp range and bandwidth are part of the specific datasheet variant; the above are the typical LMV324 features.

Package

LMV324QDR comes in a 14‑pin VSSOP (Very Small Outline Package), RoHS-compliant.

Pinout

- Pin count: 14 pins (DIP/SOIC).
- Function: Quad operational amplifier with four rail-to-rail input/output amplifiers (A, B, C, D) in one package; single-supply operation. Typical pinout: 1=OUTA, 2=−IN A, 3=+IN A, 4=VCC+, 5=+IN B, 6=−IN B, 7=OUT B, 8=OUT C, 9=−IN C, 10=+IN C, 11=VCC− (GND), 12=+IN D, 13=−IN D, 14=OUT D.

Manufacturer

- Manufacturer: Texas Instruments (TI).
- What kind of company: An American multinational semiconductor company that designs and manufactures analog, mixed-signal, and embedded processing integrated circuits; one of the world's largest semiconductor producers.

Application

LMV324QDR is a low‑power, quad rail‑to‑rail op‑amp for single‑supply use. Common applications:
- Battery-powered portable devices and wearables (sensor conditioning, audio)
- Sensor interfaces and signal conditioning (thermistors, bridges, photodiodes)
- Analog front‑ends for ADCs (buffers, gain stages, biasing)
- Active filters and simple signal processing (low/high/band-pass, integrators)
- Small‑signal amplification and buffering in medical/industrial instrumentation
- Photodiode/transimpedance and other light‑sensing circuits

Equivalent

Quad, rail-to-rail I/O op-amps with 2.7–5.5 V supply. Equivalents to LMV324QDR include:
- TI OPA4344 (quad RRIO)
- Analog Devices AD8604 (quad RRIO)
- Microchip MCP6044 (quad RRIO)
Note: pinouts and packaging vary; verify datasheets and perform a proper cross-check for your board.
