TPA1882-SR
3PEAK
Needs validationhigh risk
Pin-compatible precision op-amp with better offset but much higher power consumption and bandwidth.
Best Alternatives to OPA2188AIDR
OPA2188AIDR is a 36V, dual-channel, zero-drift precision op-amp from Texas Instruments in an SOIC-8 package. Finding a substitute requires matching its high precision and wide voltage range.
AI replacement insight
Electrical riskhigh
Major differences in quiescent current and bandwidth require circuit validation.
Package risklow
Package and pinout are a standard match.
Can it be replaced directly?
Direct replacement for OPA2188AIDR should use only Datasheet verified or Strong match candidates; many approved options still require engineering review.
Best replacement path
TPA1882-SR is the closest functional match but is not a drop-in replacement due to significant parametric differences.
Main risk
The primary risk is the 4x increase in quiescent current, which can impact the system's power budget and thermal performance.
