Product details
Overview
TLV9041IDBVR 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, delivers 350 kHz gain-bandwidth product, and features ±0.6 mV input offset voltage - enabling precision signal conditioning in coin-cell-powered wearable sensors and portable electronics.
For engineers reviewing the TLV9041IDBVR datasheet, TLV9041IDBVR pinout, TLV9041IDBVR application, or TLV9041IDBVR equivalent, this page provides verified electrical specifications, SOT-23-5 package terminal mapping, real-world use cases in low-side current sensing and motion detection, and validated alternative op-amps with documented functional trade-offs.
Technical Context
The TLV9041IDBVR 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 stable architecture supports direct connection to capacitive loads up to 100 pF without external compensation.
It achieves rail-to-rail output swing with <8 mV headroom at 1.2 V supply and maintains robust performance across –40°C to +125°C, including ±0.8 µV/°C offset drift and 77 dB CMRR at 5.5 V supply - making it suitable for unidirectional current-sensing circuits and battery-operated environmental monitors where supply headroom and thermal stability are critical.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.2 V to 5.5 V - enables operation from single 1.5 V alkaline or lithium coin cells without boost converters. |
| Quiescent Current | 10 µA per amplifier - reduces battery drain in always-on sensor front-ends and wearables. |
| Gain-Bandwidth Product | 350 kHz - supports DC to ~100 kHz signal amplification in ECG, PIR, or audio preamp stages. |
| Input Offset Voltage | ±0.6 mV (typ) - ensures ≤0.1% error in 100 mV full-scale single-supply current-sense applications. |
| Input Bias Current | 1 pA (typ) - minimizes voltage error across high-impedance source networks (e.g., pH electrodes, photodiodes). |
| Rail-to-Rail I/O | Input common-mode range includes both rails; output swings within 8 mV of rails at 1.2 V - maximizes dynamic range in low-voltage systems. |
| EMI Rejection Ratio | 70 dB at 1 GHz - suppresses RF interference from Bluetooth/Wi-Fi radios in compact portable designs. |
Pinout & Package
TLV9041IDBVR is housed in a 5-pin SOT-23 (DBV) package measuring 2.9 mm × 2.8 mm, optimized for space-constrained PCB layouts in wearables and IoT edge nodes.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OUT) | Output | Amplified analog output node; drives loads up to 100 pF directly; rail-to-rail swing capability preserves signal fidelity. |
| 2 (V–) | Negative Supply / Ground | Reference node for single-supply operation; connects to system ground or negative rail; must be tied to exposed pad if used in thermal-aware layout. |
| 3 (IN+) | Noninverting Input | High-impedance (100 GΩ || 0.5 pF) input accepting signals from 0 V to V+; supports direct connection to resistive bridges or thermistors. |
| 4 (IN–) | Inverting Input | Differential input node; used in transimpedance, difference, or inverting gain configurations; matched to IN+ for low offset. |
| 5 (V+) | Positive Supply | Primary power input; accepts 1.2–5.5 V; internal regulation ensures stable biasing across supply variation and temperature. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low supply voltage operation | Functional down to 1.2 V - eliminates need for voltage regulators in 1.5 V coin-cell applications like fitness trackers. |
| Integrated RFI/EMI filtering | On-chip input filters suppress 1 GHz interference - reduces external ferrite beads and RC snubbers in radio-near designs. |
| No phase reversal on overdrive | Output remains monotonic during input overvoltage - prevents latch-up or false triggering in PIR/motion detector front-ends. |
| Robust 100 pF capacitive load drive | Stable without external isolation resistor - simplifies routing to ADC inputs or long traces in compact PCBs. |
| Wide temperature range | Specified from –40°C to +125°C - supports industrial-grade operation in building automation and automotive cabin sensors. |

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 |
|---|---|---|---|
| OPA316IDBVR | Higher quiescent current (400 µA), higher GBW (10 MHz), no 1.2 V operation | Better for higher-speed signal chains (e.g., active filters), unsuitable for coin-cell use | Select when speed outweighs power; avoid for sub-1.5 V systems |
| LPV821DBVR | Lower quiescent current (650 nA), lower GBW (6.5 kHz), same 1.2 V min supply | Better for ultra-low-power wake-up circuits; insufficient bandwidth for audio or fast PIR response | Select for nanowatt standby modes; avoid when >10 kHz signal content required |
Compared with TLV9041IDBVR, OPA316IDBVR trades 40× higher current for 28× more bandwidth, while LPV821DBVR cuts current by 15× but sacrifices 54× bandwidth - making TLV9041IDBVR the optimal balance for 10–100 kHz, 1.2–5.5 V, battery-powered signal conditioning.
