Product details
Overview
TSM104WAIDR 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 3 mV max input offset voltage (25°C), 0.4% max reference voltage tolerance (25°C), 0.9 MHz unity-gain bandwidth, 375 µA/channel supply current at 5 V, and operates across 3 V to 30 V supply range - enabling high-accuracy battery chargers and switch-mode power supplies.
For engineers reviewing the TSM104WAIDR datasheet, TSM104WAIDR pinout, TSM104WAIDR application, or TSM104WAIDR equivalent, key selection criteria include its A-grade op-amp offset performance, adjustable 2.5 V reference with 0.2 Ω dynamic impedance, rail-to-rail output swing (0 V to VCC – 2 V), input common-mode range including ground, and SOIC-16 packaging for industrial power management designs.
Technical Context
The TSM104WAIDR integrates four independent low-input-bias-current op-amps and a two-terminal adjustable shunt voltage reference sharing a common cathode terminal. Its op-amps feature input common-mode range extending to ground and output swing from 0 V to VCC – 2 V, supporting single-supply operation in sensing and error-amplifier roles.
The reference section provides 2.5 V ±0.4% (25°C) with 7 mV typical temperature drift over –40°C to 105°C, sink current capability from 0.5 mA to 100 mA, and dynamic impedance of 0.2 Ω - enabling stable closed-loop regulation without external pass transistors in SMPS feedback networks.

Use Scenario: Primary-side regulation in offline AC/DC adapters and DC/DC converters requiring isolated feedback without optocouplers. IC Role / Device Role / Timing Role: One op-amp acts as error amplifier comparing sensed output voltage to reference; reference cathode drives optocoupler LED directly. Use Value: 100 mA cathode sink current enables direct optocoupler drive without external transistor, simplifying isolation interface and improving transient response. |
| Linear Voltage Regulator Monitor | Data-Acquisition Signal Conditioning |
|
Use Scenario: Precision monitoring and protection circuitry for LDOs and linear regulators in FPGA or ASIC power domains. IC Role / Device Role / Timing Role: Op-amps compare output voltage and junction temperature against reference-derived thresholds; reference provides stable trip points. Use Value: 7 mV typical reference drift over temperature ensures thermal shutdown thresholds remain accurate across –40°C to 105°C ambient. |
Use Scenario: Front-end amplification and level-shifting of sensor signals (e.g., RTDs, strain gauges) before ADC sampling in industrial PLC modules.

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad op-amp + voltage reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TL431AIDR | Dedicated shunt reference only - no integrated op-amps; requires external amplifiers for error comparison. | Lacks quad op-amp functionality - suitable only when op-amps are already available on board or implemented digitally. | Select TL431AIDR when reference-only function is needed and space/bom cost for additional op-amps is acceptable. |
| LM324DR | Quad op-amp only - no integrated voltage reference; requires external reference IC or resistor divider from supply. | Cannot generate precise 2.5 V reference - needs external 2.5 V source (e.g., REF5025) for accurate regulation setpoints. | Choose LM324DR when design already includes a high-precision reference or uses supply-rail-based thresholds not requiring tight tolerance. |
Compared with TL431AIDR and LM324DR, the TSM104WAIDR uniquely combines A-grade op-amp precision and adjustable reference in one SOIC-16 package - eliminating inter-component matching errors, reducing PCB area by ~40%, and enabling single-chip feedback solutions where both functions are required.

FAQ
What is the maximum supply voltage rating for the TSM104WAIDR?
The TSM104WAIDR has an absolute maximum supply voltage (VCC+ to VCC−) of 36 V, but its recommended operating supply range is 3 V to 30 V. Operation above 30 V risks exceeding safe junction temperature limits and degrading long-term reliability, especially at elevated ambient temperatures. The device is rated for continuous operation at 30 V across –40°C to 105°C.
How does the TSM104WAIDR's voltage reference differ from the standard TSM104W version?
The TSM104WAIDR uses the A-grade variant with tighter specifications: 3 mV max input offset voltage (vs. 5 mV for TSM104W) and 0.4% max reference voltage tolerance at 25°C (vs. 1% for TSM104W). These improvements directly enhance regulation accuracy in closed-loop power supplies, enabling ±0.5% output stability without calibration.
Can the TSM104WAIDR operate from a single 5 V supply?
Yes, the TSM104WAIDR supports single-supply operation from 5 V. Its input common-mode range includes ground, and its output swings from 0 V to VCC – 2 V (i.e., 0–3 V), making it suitable for 5 V microcontroller-interfaced systems. Input signals referenced to ground and output loads tied to 5 V rail function correctly without level-shifting circuitry.
What is the purpose of Pin 13 (ADJUST) on the TSM104WAIDR?
Pin 13 is the voltage reference anode/adjust terminal. When used with the cathode (Pin 12), it forms a two-terminal shunt reference where external resistors between Pin 12 and Pin 13 set the output voltage according to VOUT = 2.5 V × (1 + R1/R2). This enables programmable reference voltages from 2.5 V up to 36 V while retaining the core 2.5 V bandgap accuracy.
Is the TSM104WAIDR pin-compatible with other SOIC-16 quad op-amps like the LM324?
No, the TSM104WAIDR is not pin-compatible with LM324 or generic quad op-amps. Its SOIC-16 pinout integrates four op-amps plus a dedicated voltage reference (cathode on Pin 12, adjust on Pin 13), differing fundamentally from LM324's 14-pin configuration and lack of reference functionality. Board redesign is required for substitution.
