TS931BID

Instrumentation, Op Amps, Buffer Amps Overview

The TS931BID 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 a maximum input offset voltage of 2 mV. The device draws a typical operating current of 20 µA per channel and provides an output current of 5 mA. It is housed in an SOIC-8 surface-mount package and supports an industrial temperature range from -40°C to +105°C.

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific suffix 'ID' against official STMicroelectronics documentation to confirm the exact package type and temperature grade. Ensure compatibility with the target PCB footprint for the SOIC-8 configuration. Confirm that the 2 mV offset voltage specification meets the precision requirements of the intended application circuit design.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when a single-channel amplifier with rail-to-rail output is required under a single supply. The 2 mV max offset voltage distinguishes it from lower-grade variants like the TS931A. Consider the SOIC-8 package if board space allows compared to SOT-23-5 options. Verify that the 5 mA output drive capability suffices for the connected load impedance.

Instrumentation, Op Amps, Buffer Amps Part Context

The TS931BID belongs to the TS93x series of micropower operational amplifiers. This family includes single, dual, and quad configurations designed for low-voltage operation. The 'B' designation indicates a tighter input offset voltage specification compared to other series grades. The series utilizes CMOS technology to achieve high input impedance and low power consumption simultaneously.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

Official substitutes within the same series include TS931AI (SOIC-8) and TS931BI (SOT-23-5). Verify pinout compatibility before substitution. Cross-reference datasheets for offset voltage and bandwidth differences between grade 'A', 'B', and 'I' variants.
