Product details
Overview
TSM104WAIPW 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 from 3 V to 30 V supply rails - enabling use in battery chargers and switch-mode power supplies.
For engineers reviewing the TSM104WAIPW datasheet, TSM104WAIPW pinout, TSM104WAIPW application, or TSM104WAIPW equivalent, key selection criteria include its A-grade op-amp offset performance, adjustable reference output up to 36 V, rail-to-rail output swing (0 V to VCC – 2 V), input common-mode range including ground, and 2-kV HBM ESD protection - all in a 16-pin TSSOP package.
Technical Context
The TSM104WAIPW integrates four independent low-offset op-amps and a single 2.5 V precision shunt reference with adjustable output via external resistor divider. Its op-amps feature input common-mode range extending to ground and large output swing (0 V to VCC – 2 V), supporting single-supply operation in error amplification stages.
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, low-noise voltage setting for PWM controllers and linear regulators.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 3 V to 30 V - supports wide-input industrial and automotive SMPS designs without auxiliary bias rails. |
| Input Offset Voltage (25°C) | 3 mV max - enables high-accuracy current sensing and voltage monitoring in closed-loop regulation. |
| Reference Voltage Tolerance (25°C) | ±0.4% - ensures tight output voltage accuracy in programmable power supplies and battery charge termination. |
| Unity-Gain Bandwidth | 0.9 MHz typ - sufficient for error amplifier compensation in DC-DC converters up to ~100 kHz switching frequency. |
| Supply Current per Channel | 375 µA typ at 5 V - allows low-power operation in always-on monitoring circuits and portable systems. |
| Output Voltage Swing | 0 V to VCC – 2 V - maximizes dynamic range in single-supply configurations with rail-referenced feedback networks. |
| ESD Protection | 2 kV HBM - enhances robustness during board handling and system-level ESD events in industrial environments. |
Pinout & Package
TSSOP-16 (PW) package, 5.0 mm × 4.4 mm × 1.2 mm max height, moisture sensitivity level 1, lead finish NIPDAU, RoHS compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 5, 9, 13 | Op-Amp Output (OUT1–OUT4) | Classical op-amp outputs; each drives external compensation network or gate driver input in SMPS error paths. |
| 2, 6, 10, 14 | Op-Amp Inverting Input (IN−1–IN−4) | Accepts feedback signals from output node or current-sense resistor for closed-loop control. |
| 3, 7, 11, 15 | Op-Amp Non-Inverting Input (IN+1–IN+4) | Receives reference or setpoint signal; IN+1–IN+3 often tied to VREF or divider; IN+4 used for reference monitoring. |
| 4 | VCC+ | Positive supply rail for all op-amps and reference; decoupling required within 1 cm for stability. |
| 8 | VCC− / GND | Common return for op-amps and reference cathode; requires low-impedance ground plane connection. |
| 12 | ADJUST / REF CATHODE | Connects to external resistor divider to program reference output from 2.5 V to 36 V; sinks up to 100 mA. |
| 16 | CATHODE | Alternate cathode terminal for high-current reference configurations; electrically tied to Pin 12 internally. |
Key Features
| Feature | Design Value |

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 |
|---|---|---|---|
| TLV431AIDBVR | Single adjustable shunt reference only; no integrated op-amps - requires external amplifiers for error comparison. | Limited to single-loop regulation; unsuitable for multi-output or multi-function control where TSM104WAIPW's quad op-amps provide on-chip signal conditioning. | Select when only reference precision is needed and board space permits discrete op-amp implementation. |
| LM324DR | Quad op-amp only; no integrated reference - requires external 2.5 V reference (e.g., REF3025) and additional pass components. | Higher BOM count and layout complexity; reference accuracy limited by external part tolerance and thermal drift coupling. | Select when cost is primary constraint and design can accommodate separate reference sourcing and layout overhead. |
Compared with TLV431AIDBVR and LM324DR, the TSM104WAIPW uniquely combines A-grade op-amp precision and tight-reference functionality in one die, reducing component count, interconnect noise, and thermal mismatch - directly improving long-term regulation stability in compact power modules.

FAQ
What is the operating temperature range for the TSM104WAIPW?
The TSM104WAIPW is characterized for continuous operation from –40°C to 105°C ambient temperature. This extended industrial range is validated per TI's SLOS478D datasheet and applies to all electrical specifications including input offset voltage, reference tolerance, and supply current - making it suitable for under-hood automotive auxiliary supplies and factory-floor power modules where thermal stress is significant. The TSM104WAIPW maintains its 0.4% VREF tolerance and 3 mV VIO maximum across this full range.
How does the TSM104WAIPW differ from the standard TSM104W variant?
The TSM104WAIPW is the A-grade version of the TSM104W family, distinguished by tighter parametric limits: input offset voltage is 3 mV max (vs. 5 mV for TSM104W) at 25°C and 4 mV max over temperature (vs. 6 mV), while reference voltage tolerance is 0.4% max at 25°C (vs. 1%) and 0.8% over temperature (vs. 2%). These improvements directly enhance regulation accuracy in precision power applications - the TSM104WAIPW achieves higher closed-loop stability and lower output drift without external calibration.
Can the TSM104WAIPW be used as a standalone voltage reference without using the op-amps?
Yes, the TSM104WAIPW's reference section operates independently: Pins 12 (ADJUST) and 16 (CATHODE) form the shunt reference terminals, and the internal 2.5 V bandgap remains active regardless of op-amp biasing. When used standalone, the reference delivers 2.5 V ±0.4% at 25°C with 0.2 Ω dynamic impedance and supports sink currents from 0.5 mA to 100 mA - enabling direct use in voltage-setting networks for LDOs or comparators without engaging any op-amp channel in the TSM104WAIPW.
What is the recommended PCB layout practice for minimizing noise in the TSM104WAIPW reference output?
To minimize noise on the TSM104WAIPW reference output, place a 100 nF X7R ceramic capacitor between Pin 12 (ADJUST) and Pin 8 (VCC−) within 2 mm of the device, use a solid ground plane beneath the TSSOP-16 footprint, route the ADJUST node away from switching nodes or digital traces, and avoid shared return paths between reference and op-amp output currents. TI's PW0016A package outline recommends non-solder-mask-defined pads and symmetrical stencil apertures - adhering to these ensures optimal thermal dissipation and low-inductance cathode current paths critical for maintaining the TSM104WAIPW's 7 mV typical VREF drift.
Is the TSM104WAIPW pin-compatible with other TSSOP-16 quad op-amp or reference ICs?
No, the TSM104WAIPW has a unique pinout optimized for integrated op-amp + reference functionality - its Pin 12 (ADJUST) and Pin 16 (CATHODE) configuration differs from standard quad op-amps (e.g., LM324) and standalone references (e.g., TL431). Substituting the TSM104WAIPW into an existing LM324 layout would misroute reference cathode current and disable regulation. Always verify pin mapping against TI's SLOS478D datasheet Figure 1 (top view) before PCB integration - the TSM104WAIPW requires dedicated layout per its functional partitioning.
