Product details
Overview
TLV9041IDPWR from Texas Instruments is a single-channel, rail-to-rail input/output (RRIO), ultra-low-voltage operational amplifier optimized for power-constrained systems. It operates from 1.2 V to 5.5 V supply, draws only 10 µA quiescent current per channel, features ±0.6 mV input offset voltage and 350 kHz gain-bandwidth product, and is used in coin-cell-powered wearable sensors and low-side current sensing circuits.
For engineers reviewing the TLV9041IDPWR datasheet, TLV9041IDPWR pinout, TLV9041IDPWR application, or TLV9041IDPWR equivalent, this page delivers verified electrical specs, package-validated pin functions, real-world use cases in battery-operated IoT endpoints, and two confirmed alternative op-amps with documented functional trade-offs.
Technical Context
The TLV9041IDPWR implements a low-power CMOS input stage with 1 pA typical input bias current and integrated RFI/EMI filtering on input pins. Its unity-gain stability and robust 100 pF capacitive load drive capability enable direct interface with ADC inputs and sensor signal chains without external compensation.
It supports rail-to-rail operation across –40°C to +125°C, maintains 60–77 dB CMRR over full temperature and supply range, and delivers 6.5 µVP-P integrated noise (0.1 Hz–10 Hz) - critical for high-resolution analog front-ends in energy-harvesting and ultra-low-power monitoring systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.2 V to 5.5 V - enables direct operation from 1.5 V coin cells and single Li-ion/LiPo batteries without LDO pre-regulation. |
| Quiescent Current | 10 µA/ch - reduces standby power in always-on sensor nodes; allows >10-year battery life in 20 µA average-current applications. |
| Input Offset Voltage | ±0.6 mV (typ) - ensures <0.02% error in 30 mV full-scale current-sense shunt measurements at room temperature. |
| Gain-Bandwidth Product | 350 kHz - supports stable closed-loop gain up to 100× at DC–3.5 kHz for ECG-grade bio-signal conditioning. |
| Input Bias Current | 1 pA (typ), 12 pA (max) - minimizes voltage error across high-impedance pH or ion-selective electrodes (>100 MΩ source impedance). |
| Rail-to-Rail I/O | Full swing from V– to V+ - maximizes dynamic range in single-supply 1.2 V systems where headroom is limited to <100 mV. |
| Operating Temperature | –40°C to +125°C - qualified for automotive cabin modules, industrial edge sensors, and building automation controllers. |
Pinout & Package
TLV9041IDPWR uses the DPW (X2SON-5) package: 0.80 mm × 0.80 mm, 0.35 mm height, 5-pin monolithic micro-size package with wettable flank leads for automated optical inspection (AOI).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT | Amplifier output - drives loads up to 100 pF directly; rail-to-rail swing supports full utilization of 12-bit ADC reference range. |
| 2 | IN– | Inverting input - high-impedance node (100 GΩ || 0.5 pF); requires guard ring routing in PCB layout for sub-pA leakage-critical designs. |
| 3 | V– | Negative supply or ground - serves as return path for input common-mode and output current; must be low-impedance for PSRR integrity. |
| 4 | IN+ | Noninverting input - matched to IN– for <10 µV offset drift; internal EMI filter suppresses RF ingress above 1 GHz. |
| 5 | V+ | Positive supply - accepts 1.2 V minimum; supply rejection remains >60 dB up to 100 kHz, enabling noisy digital supply sharing. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low supply voltage | Operates down to 1.2 V - eliminates need for boost converters in button-cell-powered wearables and disposable medical patches. |
| Integrated EMI/RFI filtering | Input pins reject >70 dB interference at 1 GHz - prevents corruption of weak sensor signals in Bluetooth/Wi-Fi coexistence environments. |
| No phase reversal | Remains stable under input overdrive - avoids latch-up or false triggering in PIR motion detectors during transient light exposure. |
| Low 0.1–10 Hz noise | 6.5 µVP-P - enables accurate DC-coupled amplification of thermopile or strain gauge outputs without AC coupling artifacts. |
| High temperature grade | Specified from –40°C to +125°C - supports deployment in engine bay sensors, smart thermostats, and industrial motor control feedback loops. |
Applications
| Wearable Fitness Monitor | Single-Supply Current Sensing |

Equivalent & Alternatives
The following parts are listed as comparable options for similar low-power, rail-to-rail op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV9001IDBVR | Higher IQ (60 µA), wider GBW (1 MHz), same 1.2 V min supply, but no integrated EMI filter. | Better for higher-speed sensor interfaces (e.g., ultrasonic distance sensing), less suitable for RF-noisy environments. | Choose TLV9001IDBVR when bandwidth >350 kHz is required and board-level EMI mitigation is feasible. |
| OPA316IDBVR | Higher IQ (400 µA), lower offset (±100 µV), 10 MHz GBW, 2.7 V min supply - not 1.2 V compatible. | Targeted at precision instrumentation with ample power budget; incompatible with coin-cell or energy-harvesting sources. | Choose OPA316IDBVR only if supply ≥2.7 V is guaranteed and sub-100 µV offset is mandatory for calibration-critical systems. |
Compared with TLV9041IDPWR, TLV9001IDBVR trades 6× higher quiescent current for 3× bandwidth and lacks EMI hardening, while OPA316IDBVR sacrifices ultra-low-voltage operation for precision and speed - making TLV9041IDPWR uniquely suited for 1.2–1.5 V battery longevity-critical designs.
