TSV912AIST

Instrumentation, Op Amps, Buffer Amps Overview

The TSV912AIST is a dual general-purpose operational amplifier manufactured by STMicroelectronics, housed in an 8-pin MSOP package with tape and reel packaging. It features rail-to-rail input and output capabilities, supporting single supply voltages from 2.5 V to 5.5 V. The device offers an 8 MHz gain-bandwidth product and a typical slew rate of 4.5 V/µs at 5 V. Key electrical parameters include a maximum input offset voltage of 1.5 mV at 5 V, ultra-low input bias current of 0.00001 µA (10 pA) at 5 V, and a maximum quiescent current of 2.2 mA at 5 V. It provides a typical output current of 35 mA and has an input noise voltage density of 27 nV/√Hz.

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific suffix 'IST' corresponds to the 8-pin MSOP tape and reel configuration as documented. Confirm that the A-grade specification aligns with the required maximum input offset voltage limits for your design. Ensure compatibility with the 2.5 V to 5.5 V single supply range. Check for RoHS compliance status if required by your manufacturing standards. Validate the active part status before finalizing procurement plans.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when both rail-to-rail I/O and low power consumption are critical within a 5.5 V maximum supply constraint. The A-grade variant is appropriate for applications demanding tighter input offset voltage specifications compared to standard grades. Consider the MSOP package size for space-constrained PCB layouts. Evaluate the 8 MHz bandwidth against signal frequency requirements to ensure adequate speed without excessive power draw.

Instrumentation, Op Amps, Buffer Amps Part Context

This device belongs to the TSV91x family of CMOS operational amplifiers designed for low-voltage, high-speed applications. The family includes single (TSV911), dual (TSV912), and quad (TSV914) variants. The TSV912AIST specifically denotes the dual-channel version with A-grade accuracy in an MSOP tape-and-reel package. It shares core electrical characteristics with other family members but differs in channel count and physical packaging.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

Direct pin-compatible substitutes within the same family include TSV911IST (single channel) and TSV914IST (quad channel). For different packages, verify equivalent electrical specs such as GBW, offset voltage, and supply voltage range. Cross-reference with TSV912IQ2T if DFN-8 packaging is acceptable, noting potential differences in thermal performance or mechanical fit.
