TSV994AIDT

Instrumentation, Op Amps, Buffer Amps Overview

The TSV994AIDT is a quad operational amplifier from STMicroelectronics, featuring rail-to-rail input and output capabilities. It operates on a single supply voltage ranging from 2.5 V to 5.5 V. Key electrical parameters include a gain-bandwidth product of 20 MHz, a slew rate of 10 V/µs, and a maximum input offset voltage of 1.5 mV for the A grade. The device consumes a typical operating current of 820 µA and provides an output current of 35 mA per channel. It exhibits an ultra-low input bias current of 10 pA and high common-mode rejection ratio of 82 dB. The component is housed in a SOIC-14 package and functions within a temperature range of -40°C to +125°C.

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific ordering suffix to confirm the tape and reel packaging configuration, as indicated by the DT suffix. Ensure the component grade matches the required input offset voltage specifications, specifically checking for the A-grade designation which guarantees the 1.5 mV maximum Vos. Confirm the SOIC-14 package availability aligns with your PCB footprint requirements and soldering process capabilities.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when both rail-to-rail input and output are required alongside moderate bandwidth. It is suitable for designs needing low power consumption under 1 mA while maintaining high output drive capability. Consider the 20 MHz GBP for applications requiring faster response than micropower amplifiers but lower speed than high-performance op-amps. Verify stability with capacitive loads, noting it is stable for gains greater than or equal to 4.

Instrumentation, Op Amps, Buffer Amps Part Context

This part belongs to the TSV99x family of low-voltage CMOS operational amplifiers. The family includes single, dual, and quad variants, offering consistent electrical characteristics across channel counts. The TSV994AIDT represents the quad version with A-grade offset voltage specifications. It utilizes BiCMOS technology to balance speed and power efficiency, distinguishing it from pure CMOS or bipolar counterparts in the same voltage range.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

Check for other members of the TSV99x family, such as TSV991 or TSV992, if fewer channels are sufficient. Verify compatibility with similar rail-to-rail, low-voltage quad op-amps from other manufacturers, ensuring pinout and electrical parameter alignment.
