LT1800IS8 | Linear Technology Precision Low Noise Op-Amp Stock Overview, Price Trend & Equivalent Cross Replacement Guide
소개
LT1800IS8 is a classic single-channel high-speed precision op-amp from Linear Technology (now part of ADI), 80MHz gain bandwidth, 25V/μs slew rate, rail-to-rail input & output, ultra-low offset voltage and input bias current, SOIC-8 industrial packaging. Operating supply range covers 2.3V–12.6V, inputs can exceed power rail without phase reversal, ideal for low-noise signal conditioning, sensor acquisition, portable test instruments and medical front-end signal circuits.
In mid-2026, ADI shifts wafer production capacity to AI server high-speed signal chain chips, sharply cutting factory shipment allocation for legacy Linear industrial op-amps. Lead time of LT1800 series extends to 18–26 weeks globally, spot prices climb 15%~35% month-on-month. LXBCHIP maintains sufficient original spot inventory of LT1800IS8 and full LT series analog ICs to support stable supply for industrial & medical device manufacturers.
1. Global Analog Chip Supply & Our Stock Edge
- Factory allocation: LT series precision op-amp wafer allocation reduced by 22%; authorized distributors only receive limited monthly quota, priority given to large long-term contract customers.
- Channel instability: Small electronic vendors supply bulk reel stock with mixed production batches, inconsistent noise performance affecting precision measurement equipment accuracy.
- LXBCHIP inventory: Over 15,000pcs brand-new original LT1800IS8 in tape & reel packing, complete date code traceability, industrial temperature grade full stock. We support one-stop BOM matching with Linear power management ICs & voltage references.
- Shipment service: Small sample orders shipped same day; large batch orders support customized split delivery, global air freight with short transit cycle.
2. Current Tiered Purchase Price (USD, brand new SOIC-8 original reel)
- 1–99 pcs: $4.28 / pc
- 100–499 pcs: $3.65 / pc
- 500–4999 pcs: $3.12 / pc
- ≥5000 pcs: Large order preferential price upon consultation
3. Two Categories of Replacement Solutions
Linear Pin-to-Pin Cross Models (PCB unchanged, circuit parameters consistent)
- LT1801IS8: Dual-channel version of LT1800, same noise & speed performance, for multi-sensor signal boards
- LT1802IS8: Quad-channel op-amp, cost-effective for multi-channel acquisition modules
ADI Compatible Upgrade Alternatives (Minor circuit parameter tuning)
- AD8065: Higher bandwidth low-noise op-amp, direct performance upgrade for high-speed precision measurement equipment
4. Main Application Fields
Industrial sensor signal conditioning, portable medical monitoring front-end circuits, laboratory precision test instruments, battery-powered data loggers, low-noise industrial control signal amplifiers
