TS931AIDT

Instrumentation, Op Amps, Buffer Amps Overview

The TS931AIDT is a single-channel micropower operational amplifier from STMicroelectronics, featuring CMOS inputs and rail-to-rail output swing. It operates on a single supply voltage ranging from 2.7 V to 10 V. Key electrical parameters include a gain-bandwidth product of 100 kHz, a slew rate of 50 V/µs, and an input offset voltage of 10 mV. The device draws a typical operating current of 20 µA per channel and provides an output current of 5 mA. It exhibits an input bias current of 150 pA, a common-mode rejection ratio of 55 dB, and an input voltage noise density of 76 nV/√Hz. The component is housed in an SOIC-8 surface-mount package and supports operation temperatures from -40°C to +105°C.

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific suffix 'DT' corresponds to the SOIC-8 reel packaging configuration as indicated by distributor listings. Confirm that the 'A' designation aligns with the standard offset voltage specifications rather than the lower offset variant. Ensure compatibility with the required temperature range and package footprint before finalizing procurement orders.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when designing systems that require low quiescent current alongside moderate speed performance. The CMOS input stage minimizes loading effects on high-impedance sources. Verify that the 10 mV offset voltage meets the precision requirements of the application, as lower offset variants exist within the same family.

Instrumentation, Op Amps, Buffer Amps Part Context

The TS931AIDT belongs to the TS93x series of operational amplifiers, which includes single, dual, and quad configurations. This series is engineered for battery-operated applications due to its low power consumption and wide supply voltage range. The family offers space-saving packages such as SOT23-5 and SO-8, facilitating compact board designs.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

Check for direct pin-compatible substitutes within the TS93x family, such as the TS931IDT or TS931AIN, ensuring the package type matches the design constraints. Verify if alternative low-power op-amps from other manufacturers meet the specific 100 kHz bandwidth and 50 V/µs slew rate requirements.
