TSV521AICT

Instrumentation, Op Amps, Buffer Amps Overview

The TSV521AICT is a single-channel CMOS operational amplifier from the TSV52xA series, designed for low-voltage and low-power applications. It features rail-to-rail input and output capabilities with a gain bandwidth product of 1.15 MHz typical at 5 V. The device consumes only 45 μA typical supply current at 5 V, offering an outstanding speed-to-power ratio. Key electrical parameters include a maximum offset voltage of 800 μV, a typical input bias current of 1 pA, and operation within a supply voltage range of 2.7 to 5.5 V. It is unity-gain stable on a 100 pF capacitor and holds AEC-Q100 qualification.

Instrumentation, Op Amps, Buffer Amps Feature Summary

• Rail-to-rail input and output functionality enables full signal swing in low-voltage systems.
• Ultra-low power consumption of 45 μA extends battery life in portable devices.
• High ESD tolerance and wide temperature range support operation in harsh automotive environments.
• AEC-Q100 qualified status ensures reliability for automotive-grade applications.

Instrumentation, Op Amps, Buffer Amps Applications

• Sensor interfaces requiring high impedance matching
• Battery-supplied and portable electronic equipment
• Harsh automotive applications

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific suffix 'ICT' against official STMicroelectronics documentation to confirm package type (typically SC-70) and tape-and-reel configuration. Ensure the component meets AEC-Q100 requirements if used in automotive contexts. Cross-reference the datasheet revision date to confirm parameter consistency, as specifications may evolve. Confirm that the single-channel variant matches the system design needs compared to dual or quad versions.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select the TSV521AICT when a single op-amp channel is required with minimal power draw and rail-to-rail performance. It is suitable for designs constrained by low supply voltages between 2.7 V and 5.5 V. Consider this part over other family members if space is limited due to its small industrial package. Verify that the 1.15 MHz bandwidth and 800 μV max offset voltage meet the precision and speed requirements of the target application.

Instrumentation, Op Amps, Buffer Amps Part Context

The TSV521AICT belongs to the TSV52x and TSV52xA series of CMOS operational amplifiers manufactured by STMicroelectronics. This family includes single (TSV521), dual (TSV522), and quad (TSV524) variants with compatible pinouts. The series is engineered for high merit factors, balancing speed and power consumption. The 'A' suffix typically denotes an automotive-grade or enhanced specification variant within the lineup, distinguished by its AEC-Q100 qualification.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

Direct replacements within the same family include the TSV521 (standard grade) if automotive qualification is not strictly required. For multi-channel needs, consider the TSV522 (dual) or TSV524 (quad). Other ST CMOS op-amps with similar rail-to-rail characteristics and low power profiles may serve as functional substitutes, provided pin compatibility and electrical parameters are verified.
