概述

Description

TLV74118PDQNR is a Texas Instruments TLV741-series low-power, rail-to-rail input/output operational amplifier intended for single-supply use. The PDQNR suffix indicates TI’s packaging/tape‑and‑reel option for this device.
Key points:
- Single-supply operation (typical range 2.7–5.5 V); input common-mode and output swing close to the rails.
- Unity-gain stable and low quiescent current, suitable for battery-powered designs.
- General-purpose amplifier for buffering, sensor conditioning, active filters, and other signal-conditioning tasks.
Package note:
- TI uses PDQNR to specify a particular small-package/tape‑and‑reel option; check the datasheet for exact pinout and thermal details.
How to use:
- Connect V+ to the supply and V− to ground per the datasheet; add close-by decoupling (e.g., 0.1 µF).
- Configure feedback for the desired gain; ensure inputs stay within the common‑mode range and avoid driving the output beyond its capabilities, especially with heavy loads.
For precise electrical specs (offset, gain-bandwidth, slew rate, noise) and exact package details, consult the TI TLV74118 datasheet.

Package

PDQ package. The TLV74118PDQNR is in an 8-pin leadless PDQ package (RoHS-compliant).

Pinout

8 pins. TLV74118PDQNR is an 8‑pin TI TLV device in the PDQNR package; it functions as a voltage‑detector/reset supervisor (power‑on/reset).

Manufacturer

- Manufacturer: Texas Instruments Incorporated (TI).
- Company type: A global semiconductor company that designs and manufactures analog and embedded processing integrated circuits (e.g., op-amps, data converters, microcontrollers), headquartered in Dallas, Texas.

Application

Applications of TLV74118PDQNR include:
- Sensor signal conditioning (thermocouples, RTDs, strain gauges, load cells)
- Transimpedance and current-sense amplifiers
- Active filters (low-pass, high-pass, band-pass)
- Buffering/voltage-follower stages for ADC/DAC front ends
- Battery-powered portable instrumentation and consumer electronics

Equivalent

I can’t provide exact equivalents without knowing its function and specs. TLV74118PDQNR could be an op-amp, comparator, or switch. Please share the device function, supply voltage, package, and temperature range (or a datasheet). Do you want TI-only crossrefs or cross‑manufacturer substitutes as well? I’ll then list precise equivalents.
