S-19630AB0A-K8T2U

Overview

The S-19630AB0A-K8T2U is a dual zero-drift CMOS operational amplifier designed for automotive applications with operation up to 125°C. It utilizes chopper-stabilizing techniques to achieve low input offset voltage of +50 μV max and drift of ±25 nV/°C typ across the temperature range. The device operates on a supply voltage of 4.0 V to 36.0 V, consuming 250 μA per circuit. Key electrical parameters include a gain-bandwidth product of 1.2 MHz, slew rate of 0.45 V/μs, and rail-to-rail input/output capability. It features built-in output current limiting and internal phase compensation.

Feature Summary

• Chopper-stabilized zero-drift architecture ensures minimal input offset voltage and drift over wide temperature ranges.
• Rail-to-Rail input and output functionality allows full signal swing utilization within the supply voltage limits.
• Integrated output current limit circuit protects against damage during output pin short-circuit conditions.
• Internal phase compensation eliminates the need for external components to maintain stability.

Applications

• High-accuracy current detection
• Various sensor interfaces
• Strain gauge amplifier

Procurement Notes

Verify AEC-Q100 qualification status directly with sales representatives as details are not publicly listed. Confirm that vehicle equipment usage requires prior contact with the manufacturer. Ensure ordering suffixes match specific package and environmental codes. Validate thermal resistance requirements against target PCB layout configurations before finalizing procurement.

Selection Notes

Select this component when high precision is required in automotive environments due to its low offset voltage and drift characteristics. The dual-channel configuration suits applications needing two independent amplifiers in a compact TMSOP-8 package. Consider the 470 pF maximum load capacitance limit; larger capacitors require series isolation resistors to prevent oscillation. Evaluate input crossover distortion near the upper common-mode voltage range if operating near VDD.

Part Context

This part belongs to the S-19630A family of automotive-grade CMOS operational amplifiers. The 'B' designation indicates a dual-channel configuration, while 'K8T2' specifies the TMSOP-8 tape-and-reel packaging. The 'U' suffix denotes lead-free (Sn 100%) and halogen-free compliance. These devices are engineered specifically for robust performance in demanding vehicular electronic systems.
