Product details
Overview
TLV8544PWR from Texas Instruments is a quad-channel, nanopower, rail-to-rail input/output operational amplifier designed for ultra-low-power sensing front-ends in battery-operated systems. It delivers 500 nA per channel quiescent current, 3.1 mV maximum offset voltage, and 8 kHz gain-bandwidth product across –40°C to +125°C, enabling multi-year operation in PIR motion detectors and IoT gas sensors.
For engineers reviewing the TLV8544PWR datasheet, TLV8544PWR pinout, TLV8544PWR application, or TLV8544PWR equivalent, key selection criteria include its femtoampere-level input bias current (100 fA), 1.7–3.6 V single-supply operation, EMI-hardened architecture, and TSSOP-14 package compatibility with space-constrained wireless sensor nodes.
Technical Context
The TLV8544PWR employs a complementary CMOS input stage-N-channel and P-channel differential pairs-to achieve true rail-to-rail input operation across its full supply range. Its transition region (≈400 mV near V+) introduces measurable degradation in PSRR and CMRR, requiring careful common-mode voltage placement for precision applications.
Internally compensated for unity-gain stability, the device features a 8-kHz GBP and 3.5–4.5 V/ms slew rate. Output swing is specified at ±12 mV from rails under 100 kΩ load at 3.3 V, while built-in EMI protection mitigates interference from WiFi, mobile phones, and RF transmitters.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Current | 500 nA per channel - enables >10-year coin-cell (CR2032) lifetime in always-on PIR sensors |
| Input Offset Voltage | 3.1 mV max - supports accurate DC-coupled signal conditioning in glucose monitors and thermostats |
| Input Bias Current | 100 fA - minimizes error in high-impedance transimpedance amplifiers (e.g., with >10 MΩ feedback) |
| Gain Bandwidth | 8 kHz - sufficient for low-frequency sensor outputs (PIR, gas, smoke alarm signals) without excessive noise |
| Supply Range | 1.7 V to 3.6 V - compatible with single Li-ion, Li-SOCl₂, or alkaline cells across full temperature range |
| Operating Temp | –40°C to +125°C - qualified for industrial and automotive cabin-sensing environments |
| EMI Rejection | Built-in EMI hardening - reduces susceptibility to 900 MHz/2.4 GHz RF fields in dense IoT deployments |
Pinout & Package
TSSOP-14 (PW) package: 5.00 mm × 4.40 mm body, 0.65 mm pitch, surface-mount, leaded, RoHS-compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 7, 14 | OUTA / OUTB / OUTD | Amplifier output channels A, B, D - rail-to-rail swing within 12 mV of V+ or V− at 3.3 V |
| 2, 6, 9, 13 | –INA / –INB / –INC / –IND | Inverting inputs - high-impedance (2 pF differential), sensitive to PCB leakage and guarding requirements |
| 3, 5, 10, 12 | +INA / +INB / +INC / +IND | Non-inverting inputs - rail-to-rail common-mode range enables direct connection to resistive sensor dividers |
| 4 | V+ | Positive supply rail - must be decoupled locally with ≥100 nF ceramic capacitor to maintain PSRR |
| 11 | V− | Negative supply rail - referenced to system ground; supports single-supply operation down to 1.7 V |
Key Features
| Feature | Design Value |
|---|---|

| EMI-Hardened Architecture | Integrated filtering rejects RF interference from mobile handsets and 2.4 GHz ISM-band transceivers |
| Extended Temperature Range | –40°C to +125°C operation validated for deployment in uncontrolled environments (e.g., HVAC ducts, outdoor enclosures) |
Applications
| PIR Motion Detection | Gas Sensing Systems |
|---|---|

IC Role / Device Role / Timing Role: Signal conditioning for analog sensor outputs prior to ADC sampling; powers down between BLE transmission intervals. Use Value: 1.7–3.6 V supply range accommodates aging primary batteries; EMI hardening prevents false triggers near WiFi routers. |
Use Scenario: UL-listed residential smoke alarm with ionization chamber and low-power microcontroller. IC Role / Device Role / Timing Role: Amplifies tiny ion current changes (sub-picoamp) from chamber during smoke ingress, feeding comparator threshold detection. Use Value: 100 fA input bias preserves signal integrity; –40°C to +125°C rating ensures reliability in attic or garage installations. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar nanopower operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV8804IPWR | Lower IQ (320 nA/channel) but higher VOS (4.5 mV max); same 1.7–5.5 V supply range | Better for ultra-long-life applications where offset tolerance >4 mV is acceptable | Preferred when extending battery life outweighs need for sub-3.1 mV DC accuracy |
| LPV814DR | Higher IQ (425 nA/channel), lower VOS (0.3 mV max), wider supply (1.6–5.5 V) | Suitable for precision analog front-ends requiring tighter DC specs at modest power cost | Chosen when sensor signal chain demands <0.5 mV offset drift, accepting ~15% higher current draw |
Compared with TLV8544PWR, TLV8804IPWR trades offset voltage for lower quiescent current, while LPV814DR prioritizes precision over power efficiency-making TLV8544PWR the optimal balance for cost-sensitive, battery-limited sensing nodes requiring both low power and moderate DC accuracy.

FAQ
What is the maximum operating temperature for TLV8544PWR?
The TLV8544PWR is fully specified and tested from –40°C to +125°C ambient temperature. This extended range is validated per TI's production data and supports deployment in harsh environments such as HVAC ducts, automotive cabins, and outdoor sensor housings. All electrical parameters-including quiescent current, offset voltage, and gain bandwidth-are guaranteed across this full range.
Does TLV8544PWR support true rail-to-rail output swing?
Yes, TLV8544PWR provides rail-to-rail output swing: at 3.3 V supply and 100 kΩ load, it swings within 12 mV of both V+ and V− rails. This capability preserves maximum dynamic range in low-voltage systems, especially critical when interfacing with 10- to 12-bit ADCs powered from the same supply.
Can TLV8544PWR drive capacitive loads directly?
TLV8544PWR is unity-gain stable but becomes unstable with capacitive loads >50 pF directly on the output. For reliable operation, TI recommends adding an isolation resistor (RISO) between the op-amp output and the load capacitance. Typical RISO values range from 10 Ω to 50 kΩ depending on CL and required bandwidth.
What is the input bias current specification for TLV8544PWR?
TLV8544PWR has a maximum input bias current of 100 fA at 25°C, measured per channel. This ultra-low value enables high-fidelity signal conditioning in transimpedance amplifier configurations with feedback resistors up to 100 MΩ, minimizing IB×Rf errors in gas and radiation sensors.
Is TLV8544PWR pin-compatible with other quad op-amps in TSSOP-14?
No-TLV8544PWR uses a proprietary pinout optimized for low-noise layout and thermal symmetry. It is not pin-compatible with generic quad op-amps (e.g., LM324, TLV2464). Layout reuse requires verification against the official TLV8544PWR pin function table, particularly V+ (Pin 4) and V− (Pin 11) placement.
