Product details
Overview
TSM104WIDR from Texas Instruments is a quad operational amplifier with integrated programmable voltage reference, designed for precision feedback and regulation in power control circuits. It delivers 5 mV max input offset voltage (25°C), 30 V max supply range, 0.9 MHz unity-gain bandwidth, and adjustable reference output from 2.5 V to 36 V - enabling use in switch-mode power supply error amplifiers and linear regulator reference stages.
For engineers reviewing the TSM104WIDR datasheet, TSM104WIDR pinout, TSM104WIDR application, or TSM104WIDR equivalent, key selection criteria include its dual-function integration (four op-amps + shunt reference), SOIC-16 package compatibility, –40°C to 105°C operating range, and verified performance in battery charger feedback loops and data-acquisition front-ends.
Technical Context
The TSM104WIDR integrates four independent rail-to-rail capable op-amps with a single programmable shunt voltage reference sharing the same die. Each amplifier features input common-mode range extending to ground and output swing from 0 V to VCC – 2 V, supporting low-side sensing and single-supply operation.
The reference section operates as a 2.5 V bandgap source with ±1% tolerance (25°C), adjustable via external resistor divider, and supports sink currents from 0.5 mA to 100 mA with 0.2 Ω typical dynamic impedance - enabling stable closed-loop regulation without external pass transistors.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 3 V to 30 V - supports wide-input industrial and automotive power rails without auxiliary regulators. |
| Input Offset Voltage (25°C) | 5 mV max - enables accurate error amplification in ±5% regulation loops without trimming. |
| Reference Voltage Tolerance (25°C) | ±1% - ensures initial output accuracy for 5 V or 12 V regulated supplies without calibration. |
| Unity-Gain Bandwidth | 0.9 MHz typ - sufficient for compensation of DC-DC converters up to ~100 kHz switching frequency. |
| Output Sink Current (Ref) | 100 mA max - drives optocoupler LEDs or TL431-style feedback networks directly. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad op-amp + reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TL431AILP | Standalone 2.5 V shunt reference only; no op-amps integrated. | Requires external op-amps for error amplification; increases PCB area and component count. | Select when reference-only function suffices and layout space allows discrete implementation. |
| LM324DR | Quad op-amp only; no integrated voltage reference. | Needs external reference (e.g., REF5025) for precision regulation; adds cost and thermal drift sources. | Select when existing reference infrastructure exists or when op-amp performance (e.g., higher GBW) is prioritized over integration. |
Compared with TL431AILP and LM324DR, the TSM104WIDR reduces bill-of-materials count by consolidating two critical functions into one SOIC-16 device, cuts layout area by ~40%, and eliminates inter-component thermal drift mismatch - making it optimal for space-constrained, high-reliability power management designs.

FAQ
What is the maximum supply voltage rating for the TSM104WIDR?
The TSM104WIDR supports a maximum supply voltage of 30 V across VCC+ to VCC−, with absolute maximum ratings allowing up to 36 V for short-duration transients. This 30 V operating limit enables direct use in 24 V industrial systems and automotive battery-sensed applications without external regulators, while maintaining full specification compliance over the –40°C to 105°C temperature range.
Does the TSM104WIDR include ESD protection, and what level is specified?
Yes, the TSM104WIDR includes 2-kV Human Body Model (HBM) ESD protection on all pins, as confirmed in the Absolute Maximum Ratings table of the official datasheet. This level of protection supports safe handling during assembly and enhances reliability in end-equipment exposed to routine electrostatic discharge events, such as industrial control panels or portable test instruments.
Can the TSM104WIDR's voltage reference be adjusted above 36 V?
No - the TSM104WIDR's programmable voltage reference is rated for output voltages from 2.5 V up to 36 V, as explicitly stated in the "Voltage Reference" section of the datasheet. Exceeding 36 V risks violating the absolute maximum cathode voltage rating and may cause irreversible damage; external series regulation or clamping is required for higher-voltage applications.
What is the guaranteed input offset voltage specification for the TSM104WIDR at full temperature range?
The TSM104WIDR guarantees a maximum input offset voltage of 6 mV over the full –40°C to 105°C operating temperature range, per the "Operational Amplifier Electrical Characteristics" table. This value reflects worst-case drift and ensures predictable error amplifier performance in untrimmed industrial power supplies where thermal gradients are significant.
Is the TSM104WIDR pin-compatible with the TSM104WAIDR variant?
Yes - both TSM104WIDR and TSM104WAIDR use identical SOIC-16 (D) packaging, identical pinout, and share the same footprint and solder pad layout. The only functional difference is tighter electrical specifications in the 'A' grade (e.g., 3 mV vs. 5 mV offset), making them mechanically interchangeable in existing PCB designs without layout changes.
