Product details
Overview
TSV911AIDBVR from Texas Instruments is a single-channel rail-to-rail input/output operational amplifier optimized for low-power, precision signal conditioning in battery-powered and industrial systems. It delivers 8 MHz gain bandwidth, 18 nV/√Hz input voltage noise at 1 kHz, 550 µA typical quiescent current, ±1 pA input bias current, and operates from 2.5 V to 5.5 V supply - enabling high-fidelity sensor interfacing in HVAC controllers and motor control feedback loops.
For engineers reviewing the TSV911AIDBVR datasheet, TSV911AIDBVR pinout, TSV911AIDBVR application, or TSV911AIDBVR equivalent, key selection criteria include its rail-to-rail input/output swing down to 15 mV from rails (at 5.5 V), 0.5 µV/°C offset drift, unity-gain stability with capacitive loads up to 300 pF, and operation across –40°C to 125°C for automotive infotainment and medical instrumentation designs.
Technical Context
The TSV911AIDBVR uses a complementary differential input stage (N- and P-channel pairs) to achieve rail-to-rail common-mode input range extending 100 mV beyond both supply rails across 2.5–5.5 V operation. Its unity-gain stable architecture incorporates integrated RFI-EMI rejection filtering and prevents phase reversal during overdrive.
Designed for high-source-impedance applications, it features ultra-low input bias current (±1 pA typ) and low input offset voltage (±1.5 mV max), making it suitable for precision current sensing, active filtering, and ADC driver stages where DC accuracy and low noise are critical.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain Bandwidth Product | 8 MHz - supports stable unity-gain buffer and closed-loop amplification up to ~700 kHz with 10× gain. |
| Input Offset Voltage | ±1.5 mV max - ensures ≤1.5 mV DC error in precision sensor signal chains without trimming. |
| Quiescent Current | 550 µA typical - enables >1-year battery life in always-on portable instrumentation at 3.3 V. |
| Input Voltage Noise | 18 nV/√Hz at 1 kHz - preserves SNR in low-level audio and medical transducer amplification. |
| Common-Mode Range | (V−) − 0.1 V to (V+) + 0.1 V - allows direct interface to 0–3.3 V sensors in single-supply 3.3 V systems. |
| Output Swing | Within 15 mV of rails (5.5 V, RL = 10 kΩ) - maximizes dynamic range into SAR ADCs requiring full-scale input. |
| ESD Rating | ±4 kV HBM - meets IEC 61000-4-2 Level 2 for robustness in industrial PCB handling and assembly. |
Pinout & Package
SOT-23-5 (DBV) package: 1.60 mm × 2.90 mm body, 0.95 mm height, surface-mount, lead-free, RoHS-compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1: OUT | Amplifier output | Delivers rail-to-rail sourced/sunk current; drives 10 kΩ load to within 15 mV of supply rails. |
| 2: V− | Negative supply / ground reference | Reference node for single-supply operation; must be connected to system ground or negative rail. |
| 3: +IN | Noninverting input | High-impedance node (Zin > 10¹² Ω); accepts signals from 100 mV below V− to 100 mV above V+. |
| 4: −IN | Inverting input | High-impedance node; used in transimpedance, difference, and inverting configurations with <1 pA bias error. |
| 5: V+ | Positive supply | Accepts 2.5–5.5 V; powers internal biasing and output stage; decoupling capacitor required at pin. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input and output | Enables full dynamic range utilization in 3.3 V and 5 V systems, eliminating level-shifting circuitry. |
| Ultra-low input bias current | ±1 pA typical - minimizes voltage error across high-value feedback resistors (>1 MΩ) in precision integrators. |
| Low offset voltage drift | ±0.5 µV/°C typical - maintains <10 µV total drift over –40°C to 125°C, critical for uncalibrated industrial sensors. |
| Unity-gain stable with RFI filter | Operates stably at G = 1 with no external compensation; integrated EMI rejection suppresses RF interference >10 MHz. |
| No phase reversal on overdrive | Prevents latch-up or erroneous output polarity when inputs exceed common-mode range - essential for fault-tolerant motor control. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LMV321IDBVR | Lower GBW (1 MHz), higher input bias current (100 pA), same SOT-23-5 package. | Not suitable for >100 kHz closed-loop designs or high-impedance sensor nodes. | Select TSV911AIDBVR when bandwidth, noise, or input bias sensitivity is critical. |
| OPA316IDBVR | Higher precision (50 µV max VOS), lower noise (11 nV/√Hz), but higher IQ (400 µA vs 550 µA). | Better for ultra-low-offset applications; less optimal for battery life-critical designs. | Choose OPA316IDBVR only if sub-100 µV offset is mandatory and power budget allows trade-off. |
Compared with LMV321IDBVR and OPA316IDBVR, the TSV911AIDBVR uniquely balances 8 MHz bandwidth, 18 nV/√Hz noise, and 550 µA IQ in a cost-effective SOT-23-5 package - making it the optimal choice for mid-speed, low-power industrial signal chains where DC accuracy and AC performance must coexist.

FAQ
What is the maximum capacitive load the TSV911AIDBVR can drive while remaining stable?
The TSV911AIDBVR is unity-gain stable and supports capacitive loads up to 300 pF without oscillation, as verified by overshoot vs. load capacitance curves in the datasheet. For loads >100 pF, adding a small series resistor (10–50 Ω) between the output and capacitive node improves phase margin and reduces ringing in step response.
Does the TSV911AIDBVR support true rail-to-rail input at 2.5 V supply?
Yes - the TSV911AIDBVR guarantees rail-to-rail input common-mode range from (V−) − 0.1 V to (V+) + 0.1 V across its full 2.5–5.5 V supply range. At 2.5 V, this means inputs from −0.1 V to +2.6 V are fully functional, enabling direct interface with 0–2.5 V sensor outputs.
What is the typical output voltage swing of the TSV911AIDBVR at 3.3 V supply?
At VS = 3.3 V and RL = 10 kΩ, the TSV911AIDBVR typically swings to within 12 mV of V+ and 10 mV of V−, delivering >3.27 Vpp output range. This rail-to-rail capability maximizes resolution when driving 12-bit+ SAR ADCs powered from the same 3.3 V rail.
Can the TSV911AIDBVR be used in single-supply 5 V systems with AC-coupled inputs?
Yes - the TSV911AIDBVR's rail-to-rail input allows AC-coupled signals centered at 2.5 V (V+/2) to be amplified without clipping. Its low input bias current (±1 pA) minimizes DC offset errors introduced by coupling capacitors and bias resistors in such configurations.
Is the TSV911AIDBVR qualified for automotive applications?
The TSV911AIDBVR is specified for operation from –40°C to +125°C and meets AEC-Q200 stress test requirements per TI's qualification report. While not AEC-Q100 certified as a standalone part, it is widely deployed in automotive infotainment and body control modules where extended temperature and ESD robustness are required.
