TS944BIN

Instrumentation, Op Amps, Buffer Amps Overview

The TS944BIN is a quad micropower operational amplifier from STMicroelectronics, featuring rail-to-rail output capabilities. It operates within a supply voltage range of 2.5 V to 10 V and supports temperatures from -40°C to +85°C. Key electrical parameters include a gain-bandwidth product of 10 kHz, a slew rate of 4.5 V/µs, and an input bias current of 1 pA. The device draws 1.2 µA of operating current per channel and provides a 650 µA output current capability. It utilizes a TSSOP-14 surface-mount package.

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific suffix BIN against official STMicroelectronics documentation to confirm pinout and packaging details. Ensure the component meets RoHS and REACH compliance requirements for your region. Cross-reference the datasheet revision date to validate parameter accuracy before integration into design specifications.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when designing low-voltage, battery-driven applications requiring four independent amplifiers. The rail-to-rail output maximizes dynamic range in single-supply systems. Consider the 10 kHz bandwidth limit for high-speed signals; this part is optimized for precision and power efficiency rather than high-frequency performance.

Instrumentation, Op Amps, Buffer Amps Part Context

This part belongs to the TS94x series, which includes single, dual, and quad variants. The series is characterized for operation between 2.5 V and 10 V across industrial temperature ranges. It serves as a micropower solution for general-purpose analog signal processing where power conservation is critical.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

Check for direct substitutes within the TS94x family, such as TS944IDT or TS944IPT, noting that package differences (SOIC vs. TSSOP) may require PCB layout adjustments. Verify functional equivalence if considering cross-manufacturer alternatives.
