TS942AIPT

Instrumentation, Op Amps, Buffer Amps Overview

The TS942AIPT is a dual operational amplifier from the TS94x series, manufactured by STMicroelectronics. It features CMOS inputs and operates on a single supply voltage ranging from 2.5 V to 10 V across a temperature range of -40°C to +85°C. Key electrical parameters include a micropower consumption of 1.2 µA, a gain-bandwidth product of 10 kHz, and an output current capability of 1.5 mA. The device exhibits rail-to-rail output swing, with typical performance of 2.85 V at 3 V supply with a 10 kΩ load. Input bias current is typically 1 pA, and input offset voltage is 5 mV. The slew rate is 0.0045 V/µs. It is housed in an 8-TSSOP package.

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the component status as obsolete or active through official manufacturer channels before procurement planning. Confirm the specific suffix 'I' indicates industrial temperature grade (-40°C to +85°C) and 'P' denotes TSSOP packaging. Ensure compatibility with existing design specifications regarding pinout and electrical characteristics. Check for end-of-life notifications or recommended replacement parts if availability is critical for long-term production.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when ultra-low power consumption and rail-to-rail output are required in a dual-channel configuration. The CMOS input technology provides extremely low bias current, making it suitable for high-impedance sensor applications. Consider the limited bandwidth of 10 kHz and low slew rate, which restricts usage to low-frequency signal processing tasks. Verify that the 8-TSSOP package fits the available PCB footprint and thermal requirements.

Instrumentation, Op Amps, Buffer Amps Part Context

The TS942AIPT belongs to the TS94x family of ultra-micropower operational amplifiers, which includes single, dual, and quad variants. This family is designed for applications where power efficiency is paramount, such as battery-operated equipment. The dual configuration offers two independent amplifiers in one package, saving space compared to using two single amplifiers. The series shares common characteristics like CMOS inputs and rail-to-rail output capabilities.
