TS274ACDT

Instrumentation, Op Amps, Buffer Amps Overview

The TS274ACDT is a quad operational amplifier manufactured by STMicroelectronics, utilizing silicon gate CMOS technology. It features a gain bandwidth product of 3.5 MHz and a slew rate of 5.5 V/µs. The input offset voltage is specified at 5 mV, with an input bias current of 150 pA. Operating from a single supply of 1.5 V to 8 V or dual supplies of 3 V to 16 V, it draws 1 mA of quiescent current per channel. The output can swing to ground, providing a common-mode rejection ratio of 65 dB and an input voltage noise density of 30 nV/√Hz.

Instrumentation, Op Amps, Buffer Amps Feature Summary

• CMOS architecture delivering high input impedance and extremely low input currents with minimal drift over temperature variations.
• Rail-to-rail output capability allowing the voltage to swing down to ground potential.
• Unity gain stability ensuring reliable performance in various feedback configurations.
• Excellent phase margin on capacitive loads for stable operation.

Instrumentation, Op Amps, Buffer Amps Applications

• Low consumption electronic designs requiring efficient power usage.
• Single or dual supply operational circuits.
• Applications demanding very low input bias currents.

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific suffix 'ACDT' against the official STMicroelectronics datasheet to confirm package type and temperature range. Ensure the component meets RoHS compliance requirements if mandated by your design specifications. Cross-reference the manufacturer part number with authorized distributors to validate authenticity and avoid counterfeit components.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this device when a balance between standard power consumption (1 mA/amp) and speed is required. It is suitable for applications where rail-to-rail output is necessary but JFET-level input currents are not critical. Consider alternative families like TSV91x or TSV99x if enhanced low-offset voltage or rail-to-rail input capabilities are needed for low-voltage systems.

Instrumentation, Op Amps, Buffer Amps Part Context

The TS274 belongs to the TS274 family of micropower, wide-range operational amplifiers. This series includes variants with different power consumptions, such as the TS27L4 for very low power and TS27M4 for low power. All members share the same CMOS process characteristics, offering excellent consumption-speed ratios for general-purpose analog signal processing tasks.
