Product details
Overview
TLV9041SIDBVR 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 specified across –40°C to +125°C - enabling use in coin-cell-powered wearables and IoT sensor front-ends.
For engineers reviewing the TLV9041SIDBVR datasheet, TLV9041SIDBVR pinout, TLV9041SIDBVR application, or TLV9041SIDBVR equivalent, this page delivers verified electrical parameters, package-specific terminal mapping, real-world use cases in low-power analog signal conditioning, and validated alternative options for design flexibility and supply continuity.
Technical Context
The TLV9041SIDBVR implements a low-power CMOS op-amp architecture with unity-gain stability and no phase reversal under input overdrive. Its internal RFI/EMI filtering on input pins enhances noise immunity in compact portable layouts, while robust 100 pF capacitive load drive capability supports direct connection to ADC inputs or long traces without external isolation.
This variant includes an active-high shutdown pin (SHDN), reducing quiescent current to <200 nA when disabled. Unlike the base TLV9041DBVR, the 'S' suffix denotes integrated shutdown functionality - confirmed by pin 5 (SHDN) in the DBV package and distinct electrical specs for IQSD and enable/disable timing.
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 or single Li-ion/LiPo cells without LDO pre-regulation. |
| Quiescent Current | 10 µA/ch (typ) - reduces battery drain in always-on sensor nodes; drops to <200 nA in shutdown mode. |
| Input Offset Voltage | ±0.6 mV (max ±2.25 mV) - ensures sub-1 LSB error in 12-bit ADC interfaces at 3.3 V full-scale. |
| Gain-Bandwidth Product | 350 kHz - supports stable amplification of DC–100 kHz signals (e.g., PIR motion detection outputs) with minimal phase lag. |
| Input Bias Current | 1 pA (typ), 12 pA (max) - preserves signal integrity in high-impedance pH, thermistor, or photodiode front-ends. |
| Rail-to-Rail I/O | Full swing from V– to V+ - maximizes dynamic range in single-supply systems, eliminating level-shifting circuitry. |
| Operating Temperature | –40°C to +125°C - qualified for industrial-grade wearable electronics and building automation sensors. |
Pinout & Package
TLV9041SIDBVR is housed in a 6-pin SOT-23 (DBV) package measuring 2.9 mm × 2.8 mm, with exposed pad not present. The package supports reflow soldering and is compatible with standard pick-and-place equipment.
| 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 reference range. |
| 2 | V– | Negative supply or ground - serves as reference for single-supply operation; connects to system GND or negative rail. |
| 3 | IN+ | Noninverting input - high-impedance node (100 GΩ || 0.5 pF); accepts DC-coupled sensor signals without loading. |
| 4 | IN– | Inverting input - matched impedance to IN+; used in transimpedance or differential configurations with precision feedback. |
| 5 | SHDN | Shutdown control - logic-high (≥V– + 1 V) enables amplifier; logic-low disables output and reduces IQ to <200 nA. |
| 6 | V+ | Positive supply - accepts 1.2–5.5 V; internal regulation ensures stable biasing across voltage range. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low supply voltage | Operates down to 1.2 V - eliminates need for boost converters in energy-harvesting or coin-cell designs. |
| Integrated EMI/RFI filtering | Input pins include on-die RC filters - suppresses GSM, Wi-Fi, and Bluetooth interference without external components. |
| No phase reversal | Remains stable during input overdrive - prevents latch-up or erroneous output transitions in transient-rich environments. |
| Shutdown mode | Reduces current to <200 nA - enables microcontroller-controlled sleep/wake cycles in battery-operated edge nodes. |
| Low 0.1–10 Hz noise | 6.5 µVP-P - minimizes drift in DC-coupled biosignal amplifiers (e.g., heart rate monitors) and precision sensor bridges. |
Applications
| Wearable Fitness Monitor | Single-Supply Current Sensing |

Equivalent & Alternatives
The following parts are listed as comparable options for similar low-power operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV9041DBVR | No shutdown pin; 5-pin SOT-23; identical core specs (IQ = 10 µA, GBW = 350 kHz, VOS = ±0.6 mV). | Lacks power-gating capability - unsuitable where MCU-controlled sleep modes are required. | Select TLV9041DBVR only if board layout lacks space for sixth pin and continuous operation is acceptable. |
| LPV821DBVR | Lower IQ (650 nA), lower GBW (10 kHz), higher VOS (±1.25 mV), same 1.2 V min supply. | Better for ultra-long-life applications (e.g., >10-year battery life), but insufficient bandwidth for PIR or audio paths. | Choose LPV821DBVR when micro-power dominates over speed and precision; avoid for signal chains requiring >50 kHz bandwidth. |
Compared with TLV9041DBVR, TLV9041SIDBVR adds shutdown control at the cost of one pin and slightly higher minimum supply current in active mode; compared with LPV821DBVR, it trades 65× higher IQ for 35× greater bandwidth and tighter offset - making it optimal for responsive, precision, yet still ultra-low-power sensing.

FAQ
What is the minimum operating supply voltage for TLV9041SIDBVR?
The TLV9041SIDBVR 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 the full –40°C to +125°C temperature range and is validated per TI's SBOS836H datasheet Section 6.3.
Does TLV9041SIDBVR have rail-to-rail input and output capability?
Yes, TLV9041SIDBVR provides true rail-to-rail input and output swing - its common-mode input range extends from V– to V+, and output swings within 1–8 mV of either rail depending on load and supply. This is confirmed in Section 6.7 "Output" of the official datasheet.
How does the shutdown function work on TLV9041SIDBVR?
The SHDN pin (Pin 5) is active-high: driving it ≥(V– + 1 V) enables the amplifier, while pulling it ≤(V– + 0.2 V) disables it and reduces quiescent current to <200 nA. Enable/disable times are 120–160 µs and 10 µs respectively, as measured per Section 6.7 "Shutdown".
What is the typical input bias current of TLV9041SIDBVR?
The typical input bias current of TLV9041SIDBVR is 1 pA, with a maximum of 12 pA over temperature. This ultra-low value is critical for high-impedance sensor interfaces such as photodiodes or thermistors, and is explicitly listed in Table 6-7 under "INPUT BIAS CURRENT".
Is TLV9041SIDBVR suitable for driving capacitive loads?
Yes, TLV9041SIDBVR is robustly characterized to drive up to 100 pF capacitive loads without oscillation or excessive overshoot, as verified in Figure 6-29 and Section 7.3.10 of the datasheet. For heavier loads, a small series resistor (e.g., 50 Ω) at the output is recommended.
