TS27L4ACPT

Instrumentation, Op Amps, Buffer Amps Overview

The TS27L4ACPT is a quad precision low-power operational amplifier manufactured by STMicroelectronics. It features four channels with a gain-bandwidth product of 100 kHz and a slew rate of 40 mV/us. The input offset voltage is 5 mV, and the input bias current is 150 pA. Operating from a single supply of 3 V to 16 V or dual supplies of ±1.5 V to ±8 V, it draws 60 uA per channel. The device provides 60 mA output current per channel, 65 dB CMRR, and 60 dB PSRR. Input voltage noise density is 68 nV/sqrt Hz. It is housed in a TSSOP-14 package for surface mount installation.

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific suffix 'C' indicates the commercial temperature grade (0°C to +70°C) and 'P' denotes the TSSOP-14 package. Confirm the 'T' suffix corresponds to reel packaging as indicated in distributor specifications. Ensure the component matches the exact pinout and electrical tolerances defined in the official STMicroelectronics datasheet before integration into production designs.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when application requirements prioritize minimal power consumption over high-speed performance. The 100 kHz bandwidth and 40 mV/us slew rate are sufficient for low-frequency signal processing. Compare against TS27L4IDT if industrial temperature range (-40°C to +125°C) is required instead of commercial grade. Consider the TSSOP-14 footprint constraints during PCB layout planning.

Instrumentation, Op Amps, Buffer Amps Part Context

This part belongs to the TS27L4 family of very low power CMOS quad operational amplifiers. It shares core architecture with TS27L4AMPT and TS27L4IDT but differs in temperature rating and package type. The family utilizes ST silicon gate CMOS process to achieve an optimal consumption-speed ratio compared to standard JFET devices.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

TS27L4IDT offers identical electrical characteristics but supports an extended industrial temperature range (-40°C to +125°C) and uses SOIC-14 packaging. TS27L4AMPT provides similar functionality with potential minor parameter variations. Verify pin compatibility and thermal management requirements when substituting.
