TSV522IST

Instrumentation, Op Amps, Buffer Amps Overview

The TSV522IST is a dual-channel CMOS operational amplifier from STMicroelectronics, housed in a MiniSO-8 surface-mount package. It operates within a supply voltage range of 2.7 V to 5.5 V and consumes 45 μA per device at 5 V. Key electrical specifications include a gain-bandwidth product of 1.15 MHz, a slew rate of 740 mV/μs, and an input bias current of 10 pA. The device features rail-to-rail input and output capabilities, with a maximum input offset voltage of 1.5 mV and an input voltage noise density of 61 nV/√Hz. It supports an output current of 55 mA per channel and functions reliably across a temperature range of -40°C to +125°C.

Instrumentation, Op Amps, Buffer Amps Feature Summary

• Rail-to-rail input and output stages enable full signal swing utilization near supply rails.
• High speed-to-power ratio provides 1.15 MHz bandwidth while maintaining low 45 μA quiescent current consumption.
• Low input bias current of 10 pA facilitates easy interfacing with high-impedance sensors.
• Unity gain stable on 100 pF capacitive loads ensures robust performance in various circuit configurations.

Instrumentation, Op Amps, Buffer Amps Applications

• Sensor interfaces requiring minimal loading effects
• Battery-powered portable electronic devices
• Harsh automotive environments

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific ordering suffix IST corresponds to the MiniSO-8 package and reel/cut-tape availability. Confirm AEC-Q100 qualification status if automotive compliance is required for your specific application environment. Ensure the component matches the exact pinout compatibility with industry standards referenced in the datasheet.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when a balance between moderate bandwidth (1.15 MHz) and ultra-low power consumption (45 μA) is critical. It is suitable for applications where rail-to-rail I/O is necessary but high-speed precision is not the primary constraint. Consider the MiniSO-8 package constraints for PCB layout and thermal management in dense designs.

Instrumentation, Op Amps, Buffer Amps Part Context

The TSV522IST belongs to the TSV52x family of low-voltage CMOS operational amplifiers. This series includes single (TSV521), dual (TSV522), and quad (TSV524) variants designed for compact industrial packages. The family emphasizes efficiency for battery-operated systems while maintaining sufficient performance for general-purpose analog signal conditioning tasks.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

Check for direct pin-compatible alternatives within the TSV52xA series or other STMicroelectronics low-power op-amps. Verify that substitute components match the 2.7–5.5 V supply range and MiniSO-8 footprint requirements.
