Product details
Overview
TSM104WIPWR 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 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 supplies and linear regulators.
For engineers reviewing the TSM104WIPWR datasheet, TSM104WIPWR pinout, TSM104WIPWR application, or TSM104WIPWR equivalent, key selection criteria include its dual-function integration (4 op-amps + shunt reference), TSSOP-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 TSM104WIPWR integrates four independent rail-to-rail input op-amps sharing a common supply (3 V to 30 V) and a single programmable shunt voltage reference with 2.5 V nominal output. Each amplifier features input common-mode range extending to ground and output swing from 0 V to VCC – 2 V.
The reference section operates as a 2-terminal adjustable shunt regulator with cathode current capability from 0.5 mA to 100 mA, dynamic impedance of 0.2 Ω typ, and temperature drift of 7 mV typ over –40°C to 105°C. Its reference voltage is set externally via two resistors between CATHODE, ADJUST, and VCC−.
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 external regulators. |
| Input Offset Voltage (25°C) | 5 mV max - enables accurate error amplification in ±1% voltage regulation loops. |
| Unity-Gain Bandwidth | 0.9 MHz typ - sufficient for compensation of DC-DC converters up to ~100 kHz switching frequency. |
| Reference Output Range | 2.5 V to 36 V - programmable via external resistor divider for custom feedback thresholds. |
| Reference Tolerance (25°C) | 1% max - ensures stable reference accuracy across production batches in closed-loop systems. |
| Operating Temperature | –40°C to 105°C - qualified for under-hood automotive and industrial ambient environments. |
| Total Supply Current | 4 mA max at 30 V - low quiescent draw suitable for energy-sensitive power management ICs. |
Pinout & Package
TSSOP-16 package (PW), 4.4 mm × 5.0 mm footprint, 1.2 mm max height, lead-free NIPDAU finish, MSL Level-1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 3, 5, 8, 9, 11, 13, 14 | Op-amp inputs/outputs (1IN+, 1IN−, 1OUT, 2IN+, 2IN−, 2OUT, 3IN+, 3IN−, 3OUT, 4IN+, 4IN−, 4OUT) | Standard quad-op-amp configuration with non-inverting/inverting inputs and buffered outputs per channel. |
| 2, 16 | VCC+ / VCC− | Power supply terminals - VCC+ accepts 3–30 V; VCC− serves as reference return and cathode bias node. |
| 4 | ADJUST | Reference feedback node - connects to resistor divider to set output voltage from 2.5 V to 36 V. |
| 6 | CATHODE | Shunt regulator output terminal - sinks up to 100 mA; forms adjustable reference with ADJUST and VCC−. |
| 7, 10, 12, 15 | GND-referenced nodes (unused pins in standard config) | Unused op-amp terminals - must be tied to appropriate potentials per application; not floating. |
Key Features

Use Scenario: Precision voltage and current regulation in multi-cell Li-ion charger ICs using external MOSFETs. IC Role / Device Role / Timing Role: Dual op-amp channels implement voltage and current error amplifiers; reference sets precise 2.5 V threshold for feedback comparators. Use Value: Achieves ±1% output regulation accuracy over temperature with single-device integration, reducing layout sensitivity to trace resistance. |
Use Scenario: Primary-side feedback and loop compensation in isolated flyback converters without optocoupler. IC Role / Device Role / Timing Role: One op-amp acts as transconductance error amplifier; reference provides stable bias for secondary-side sensing interface. Use Value: Enables compact, cost-effective isolated regulation with <1% reference drift and 0.9 MHz GBW for stable phase margin. |
| Linear Voltage Regulator Monitor | Data-Acquisition System Reference |
|
Use Scenario: Overvoltage/undervoltage protection and trim adjustment in high-accuracy LDOs for FPGA core supplies. IC Role / Device Role / Timing Role: Two op-amps compare regulated output against reference-derived thresholds; third implements hysteresis. Use Value: Delivers fast response (<1 µs propagation delay implied by 0.9 MHz GBW) and tight 5 mV offset for sub-10 mV trip windows. |
Use Scenario: Precision gain-setting and offset calibration in 12-bit ADC front-end stages for industrial sensors. IC Role / Device Role / Timing Role: Op-amps condition sensor signals; reference provides stable 2.5 V reference for DAC output scaling and ADC reference buffer.

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 |
|---|---|---|---|
| TL431ACDR + LM324DR | Discrete solution: separate shunt reference (2.5 V fixed) and quad op-amp (7 mV offset, 1 MHz GBW). | Lacks integrated ADJUST/CATHODE interface; requires external resistor network and PCB area for two devices. | Preferred when reference voltage must be fixed at 2.5 V and op-amp offset tolerance >5 mV is acceptable. |
| TSM104WAIPWR | Same pinout and function, but tighter specs: 3 mV max offset (25°C), 0.4% reference tolerance (25°C), 0.5 mV typical offset. | Delivers higher regulation accuracy in battery fuel gauging or medical power supplies where <0.5% total error is required. | Select when design targets <±0.5% output regulation and can support A-grade cost premium. |
Compared with TL431ACDR+LM324DR, TSM104WIPWR reduces component count and layout complexity while maintaining comparable bandwidth and thermal stability; compared with TSM104WAIPWR, it trades 2 mV higher offset and 0.6% looser reference tolerance for lower unit cost in cost-sensitive industrial power modules.

FAQ
What is the maximum cathode current supported by the TSM104WIPWR reference section?
The TSM104WIPWR reference section supports up to 100 mA cathode current (IKA), enabling direct drive of optocoupler LEDs or small-signal transistors in isolated feedback paths without external buffering. This rating is specified under absolute maximum conditions and aligns with its 0.2 Ω dynamic impedance for stable regulation across load steps. The TSM104WIPWR maintains regulation down to 0.5 mA minimum cathode current.
Does the TSM104WIPWR require external compensation components for stability in voltage regulator applications?
Yes, the TSM104WIPWR op-amp sections require external compensation (e.g., capacitor across feedback resistor) when used in closed-loop configurations like error amplifiers. Its 0.9 MHz unity-gain bandwidth and capacitive load sensitivity mean stability depends on loop gain, phase margin, and PCB parasitics - no internal compensation is provided. The TSM104WIPWR datasheet Figure 4 shows typical compensation networks for SMPS feedback.
Can the TSM104WIPWR operate with a single 5 V supply?
Yes, the TSM104WIPWR operates from 3 V to 30 V supply range, including single 5 V rails. At VCC = 5 V, it delivers 375 µA/channel supply current, 0.9 MHz GBW, and output swing from 0 V to 3 V - sufficient for interfacing with 3.3 V logic or driving low-voltage comparators. Input common-mode range includes ground, supporting direct connection to 0 V-referenced sensors.
How does the TSM104WIPWR's reference voltage adjustability work?
The TSM104WIPWR reference voltage is set by an external resistor divider between CATHODE (pin 6), ADJUST (pin 4), and VCC− (pin 2). With VREF = 2.5 V internally, output voltage follows VOUT = 2.5 V × (1 + R1/R2), where R1 connects CATHODE to ADJUST and R2 connects ADJUST to VCC−. This allows precise programming from 2.5 V to 36 V while retaining the TSM104WIPWR's 1% reference tolerance and 7 mV tempco.
Is the TSM104WIPWR pin-compatible with other TSSOP-16 quad op-amps?
No, the TSM104WIPWR has a unique pinout optimized for integrated reference functionality (e.g., dedicated CATHODE and ADJUST pins), differing from standard quad op-amps like LM324 or TL074. Its pin mapping is specific to the TSM104 family and documented in TI SLOS478D - direct replacement requires schematic and layout revision. The TSM104WIPWR cannot be substituted without verifying signal routing and power domain connections.
