Product details
Overview
TLV9041UIDBVR from Texas Instruments is a single-channel, rail-to-rail input/output (RRIO), ultra-low-voltage operational amplifier optimized for battery-powered applications. It operates from 1.2 V to 5.5 V supply, draws only 10 µA quiescent current per channel, and features ±0.6 mV input offset voltage and 350 kHz gain-bandwidth product - enabling precision signal conditioning in coin-cell–powered wearables and IoT sensors.
For engineers reviewing the TLV9041UIDBVR datasheet, TLV9041UIDBVR pinout, TLV9041UIDBVR application, or TLV9041UIDBVR equivalent, this page delivers verified electrical specs, SOT-23-5 package mapping, real-world use cases in low-side current sensing and motion detection, and two validated alternative op-amps with documented functional trade-offs.
Technical Context
The TLV9041UIDBVR 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 simplify layout in space-constrained designs without external compensation.
It supports full rail-to-rail input common-mode range (V– to V+) and output swing within 1–8 mV of rails under 10 kΩ–100 kΩ loads. The device maintains specified performance across –40°C to +125°C and achieves 65° phase margin at G = +1 with 10 pF load.
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 Li-ion single-cell systems without LDO pre-regulation. |
| Quiescent Current | 10 µA/ch (typical) at 5.5 V - reduces battery drain in always-on sensor front-ends and wearable health monitors. |
| Input Offset Voltage | ±0.6 mV (max ±2.25 mV) - ensures <1% error in 100 mV full-scale analog front-ends without trimming. |
| Gain-Bandwidth Product | 350 kHz - supports DC–100 Hz biosignal amplification (ECG, PPG) and slow-loop control feedback. |
| Input Bias Current | 1 pA (typical), ≤12 pA (max) - minimizes voltage error across high-impedance sources like pH electrodes or photodiode transimpedance nodes. |
| Rail-to-Rail I/O | Input: V– to V+; Output: within 1–8 mV of rails - maximizes dynamic range in single-supply 1.2 V–3.3 V systems. |
| EMI Rejection Ratio | 70 dB at 1 GHz - suppresses RF interference from Bluetooth/Wi-Fi co-location in earbuds and smartwatches. |
Pinout & Package
TLV9041UIDBVR is packaged in a 5-pin SOT-23 (DBV) footprint measuring 2.9 mm × 2.8 mm, optimized for high-density PCB layouts in portable electronics.
| 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 ADC input range. |
| 2 | V– | Negative supply or ground reference - serves as return path for single-supply operation; connects to system GND or negative rail. |
| 3 | IN– | Inverting input - accepts feedback network; high impedance (100 GΩ || 0.5 pF) prevents loading of high-Z sensors. |
| 4 | IN+ | Noninverting input - used for reference voltage or sensor signal injection; EMI-filtered for noise immunity. |
| 5 | V+ | Positive supply - accepts 1.2–5.5 V; internal regulation ensures stable biasing across wide voltage range. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low supply voltage operation | Functional down to 1.2 V - eliminates need for boost converters in CR2032-powered devices. |
| Integrated RFI/EMI filtering | On-chip input filters reduce susceptibility to 900 MHz–2.4 GHz emissions - critical for wireless earbud microphone preamps. |
| No phase reversal on overdrive | Stable output polarity during input overvoltage - prevents latch-up in unidirectional current-sense circuits with transient surges. |
| Low 0.1–10 Hz noise | 6.5 µVPP - enables clean amplification of sub-Hz physiological signals (respiration, pulse waveforms). |
| Wide temperature range | Specified from –40°C to +125°C - supports automotive cabin sensors and industrial edge nodes without derating. |
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 quiescent current (60 µA vs. 10 µA); lower GBW (1 MHz vs. 350 kHz); no EMI filtering. | Better for higher-speed signal chains where power budget allows; unsuitable for sub-µA standby modes. | Select when bandwidth >500 kHz is required and 1.2 V operation is not mandatory. |
| OPA316IDBVR | Higher IQ (400 µA); wider supply range (1.8–5.5 V); lower offset (±0.25 mV); no 1.2 V support. | Preferred for precision instrumentation where offset dominates error budget and coin-cell operation is unnecessary. | Choose when 1.2 V operation is not needed and offset voltage <0.3 mV is critical for measurement accuracy. |
Compared with TLV9041UIDBVR, TLV9001IDBVR trades 6× higher quiescent current for 3× bandwidth, while OPA316IDBVR sacrifices ultra-low-voltage capability for superior DC precision - making TLV9041UIDBVR uniquely suited for 1.2 V–3.3 V always-on sensing nodes.

FAQ
What is the minimum supply voltage for TLV9041UIDBVR?
The TLV9041UIDBVR operates down to 1.2 V, enabling direct use with 1.5 V alkaline or lithium coin cells without voltage boosting. This specification is guaranteed across –40°C to +125°C and is validated per TI's SBOS836H datasheet Section 6.3. At 1.2 V, key parameters including gain-bandwidth (350 kHz), rail-to-rail input range, and 10 µA quiescent current remain fully functional in the TLV9041UIDBVR variant.
Does TLV9041UIDBVR include EMI filtering?
Yes, TLV9041UIDBVR integrates on-chip RFI and EMI filtering on its input pins, delivering 70 dB rejection at 1 GHz per Section 6.7 of the datasheet. This feature is confirmed for the TLV9041UIDBVR ordering variant and is critical for maintaining signal integrity in wireless-enabled devices like Bluetooth earbuds and smartwatches where RF coupling into analog front-ends is prevalent.
What is the input offset voltage specification for TLV9041UIDBVR?
The TLV9041UIDBVR has a maximum input offset voltage of ±2.25 mV at 25°C and ±2.5 mV across –40°C to +125°C, with a typical value of ±0.6 mV. These values are explicitly listed in Table 6-1 (Electrical Characteristics) of the SBOS836H datasheet under "OFFSET VOLTAGE" for the TLV9041UIDBVR variant, confirming its suitability for precision DC-coupled applications such as low-side current sensing.
Is TLV9041UIDBVR unity-gain stable?
Yes, TLV9041UIDBVR is unity-gain stable and characterized for G = +1 operation with ≥65° phase margin when driving 10 pF loads, as shown in Figure 6-31 (Phase Margin vs Capacitive Load) and confirmed in Section 7.3. This stability holds across the full 1.2 V–5.5 V supply range and –40°C to +125°C temperature range, eliminating the need for external compensation in most buffer and gain-of-one configurations.
What package type does TLV9041UIDBVR use?
TLV9041UIDBVR uses the DBV package: a 5-pin SOT-23 variant measuring 2.9 mm × 2.8 mm. This is explicitly stated in the "Device Information" table and Figure 5-2 (TLV9041U DBV Package) of the SBOS836H datasheet. Pin 1 is OUT, Pin 2 is V–, Pin 3 is IN–, Pin 4 is IN+, and Pin 5 is V+, matching the standard SOT-23 pinout orientation for single-channel op-amps.
