STMicroelectronics TSM106ID

Overview

TSM106ID from STMicroelectronics is a dual operational amplifier and voltage comparator IC in an 8-pin SOIC package, featuring rail-to-rail input/output swing, 1.5 MHz gain-bandwidth product, ±15 V maximum supply voltage, and 1.1 mA typical quiescent current per channel. It serves as a precision signal conditioning and level-detection component in industrial sensor interfaces and power-supply monitoring circuits.

For engineers reviewing the TSM106ID datasheet, TSM106ID pinout, TSM106ID application, or TSM106ID equivalent, this device supports dual-channel analog signal processing with integrated comparator functionality-enabling compact, low-power designs for voltage supervision, window detection, and analog front-end buffering where space and supply headroom are constrained.

Technical Context

The TSM106ID integrates two independent op-amps and one open-collector comparator on a single die, sharing common supply rails. Its op-amp inputs operate down to the negative rail and up to V_CC – 1.5 V, while the comparator features internal hysteresis (typically 6 mV) and supports pull-up voltages up to 36 V independent of V_CC.

This architecture enables simultaneous amplification and threshold comparison without external components-e.g., amplifying a thermistor signal then comparing it against a reference-reducing BOM count and PCB footprint in closed-loop control and fault-detection systems operating from ±5 V to ±15 V supplies.

FAQ

Can the TSM106ID operate from a single 5 V supply?

No. The TSM106ID requires dual supplies (e.g., ±5 V) or asymmetric rails (e.g., 0 V and +12 V) but does not support true single-supply operation down to ground on both inputs simultaneously. Its input common-mode range extends to the negative rail but only up to V_CC – 1.5 V-not full rail-to-rail on the positive side in single-supply mode. For 5 V-only designs, consider the TSX912 or LMV358.

What is the purpose of the internal hysteresis in the comparator section?

The internal hysteresis (~6 mV typical) prevents output oscillation when the comparator input sits near the switching threshold under noisy conditions. It creates distinct upper and lower trip points, eliminating the need for external positive feedback resistors-simplifying design and improving immunity to EMI in industrial environments where sensor signals often carry high-frequency interference.

Is the comparator output compatible with 3.3 V logic systems?

Yes. The open-collector output can be pulled up to 3.3 V using an external resistor. When active (low), it sinks current compatible with standard CMOS/TTL logic inputs. No level-shifter is required, provided the pull-up source is referenced to the same ground as the TSM106ID and the load does not exceed the 20 mA sink capability specified in the datasheet.

How does the TSM106ID differ from the TSM103 series?

The TSM103 contains two op-amps only, with no comparator. The TSM106ID adds a fully functional comparator with independent hysteresis and open-collector output-making it suitable for applications requiring both amplification and decision-making in one package. Electrical specs (GBW, offset, supply range) are closely matched, enabling drop-in replacement where comparator functionality is added.
