概述

Description

LM258AYDT is a Texas Instruments dual general-purpose operational amplifier (an LM258/LM358-family device) in a single package. It is designed for low-power, single-supply operation and common in signal conditioning and buffering tasks.
Key points:
- Dual op-amps in one 8-pin package; two independent amplifiers (A and B).
- Not rail-to-rail; input common-mode includes the negative rail; output can swing close to ground but won’t reach the positive rail.
- Wide single-supply voltage range (typical from a few volts up to about 30–32 V).
- Low quiescent current and relatively low input bias, suitable for battery-powered apps.
- Typical uses: sensor conditioning, active filters, voltage followers, summing/integrator circuits.
Pinout (8-pin package, common for LM358/LM258): V+, V−, Out A, In+ A, In− A, In− B, In+ B, Out B (check exact package variant).
Packaging: AYDT denotes a specific TI package/temperature variant; verify the exact package (DIP-8, SOIC-8, etc.) and temperature grade in the datasheet.

Features

LM258AYDT features:
- Dual general‑purpose operational amplifiers in one package
- Wide supply range: 3 V to 32 V (single supply) or ±1.5 V to ±16 V
- Unity‑gain stable
- Input common‑mode range includes the negative rail
- Output can swing toward the negative rail (ground) but is not rail‑to‑rail
- Not rail‑to‑rail on input or output
- Typical gain‑bandwidth around 1 MHz; moderate slew rate
- Low input bias current and low input offset voltage
- Temperature range: wide (commonly −40 °C to +125 °C)
- Available in 8‑pin packages (DIP/SOIC variants)
Note: exact numbers (GBW, offset, bias) vary by device revision and manufacturer tolerances; check the current datasheet for precise specs.

Package

LM258AYDT comes in an 8-pin Small Outline Integrated Circuit (SOIC-8) surface-mount package.

Pinout

- Pin count: 8 pins
- Function: Dual operational amplifier (two independent op-amps). Each op-amp has a non-inverting input, an inverting input, and an output. Typical pinout (DIP/SOIC-8):
1 = Output A
2 = Inverting input A
3 = Non-inverting input A
4 = V– (GND)
5 = Non-inverting input B
6 = Inverting input B
7 = Output B
8 = V+ (Vcc)

Manufacturer

Manufacturer: Texas Instruments (TI).
What kind of company: TI is an American multinational semiconductor company that designs and manufactures analog, mixed-signal, and embedded processing ICs; it acquired National Semiconductor, the original source of the LM258 family.

Application

LM258AYDT is a dual general‑purpose op‑amp. Typical application areas include:
- Single‑supply signal conditioning and buffering (3–32 V)
- Audio preamplifier and line‑driver stages
- Active filters (low/high/band‑pass), tone controls
- Amplifiers for sensors/transducers (gain, offset, level shift)
- Inverting/non‑inverting, summing, differential amplifiers; integrators/differentiators
- ADC/DAC front‑ends and feedback control loops
- Servo regulators, power‑supply monitoring, instrumentation circuits

Equivalent

Direct equivalents (pin-for-pin):
- LM358 (dual op-amp; same pinout)
- LM2904 (dual op-amp; pin-compatible)
- LM258/LM258A (same family; variant packaging)
Notes: These can replace LM258AYDT in many designs, but verify supply voltage, input/output swing, and rail requirements for your circuit. Non-identical substitutes (e.g., LMV358) may have different specs.
