Product details
Overview
TLV9051IDBVR from Texas Instruments is a single-channel, rail-to-rail input/output CMOS operational amplifier optimized for low-voltage, high-slew-rate applications. It delivers 15 V/µs slew rate, 5 MHz unity-gain bandwidth, ±0.33 mV input offset voltage, 330 µA quiescent current, and operates from 1.8 V to 6.0 V supply. It is used in photodiode amplification, low-side current sensing, and sensor signal conditioning where precision, speed, and power efficiency are critical.
For engineers reviewing the TLV9051IDBVR datasheet, TLV9051IDBVR pinout, TLV9051IDBVR application, or TLV9051IDBVR equivalent, this page provides verified electrical specifications, SOT-23-5 package terminal mapping, real-world use scenarios in HVAC and white goods, and two validated alternative op amps with documented functional and application differences.
Technical Context
The TLV9051IDBVR employs a CMOS input stage enabling ultra-low input bias current (2 pA typical) and rail-to-rail common-mode input range extending 0.1 V beyond both rails. Its high slew rate is achieved via internal compensation that maintains unity-gain stability while supporting capacitive loads up to 150 pF without external compensation.
It features integrated RFI/EMI filtering and eliminates phase reversal under overdrive conditions-critical for robust sensor front-ends. The device's open-loop output impedance is resistive, simplifying stabilization with higher capacitive loads compared to conventional op amps.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Slew Rate | 15 V/µs - enables fast settling for 100-mV step responses in ≤0.75 µs (0.1%) with 100-pF load |
| Unity-Gain Bandwidth | 5 MHz - supports stable closed-loop operation at gains ≥1 with predictable frequency response |
| Input Offset Voltage | ±0.33 mV (typ) - ensures <1 LSB error in 12-bit ADC interfaces at 5-V full-scale |
| Quiescent Current | 330 µA per amplifier - allows battery-powered operation >1 year in always-on sensor nodes (3-V coin cell) |
| Supply Voltage Range | 1.8 V to 6.0 V - interoperable with Li-ion, 3.3-V, and 5-V systems without level-shifting |

Equivalent & Alternatives
The following parts are listed as comparable options for similar operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA391DBVR | Higher GBW (4.5 MHz vs 5 MHz), lower noise (7 nV/√Hz), but higher IQ (560 µA); no EMI filter | Better for ultra-low-noise audio preamps; less suitable for noisy industrial motor control | Choose OPA391DBVR when noise dominates design; TLV9051IDBVR preferred for EMI-prone environments with tight power budgets |
| MCP6001T-E/OT | Lower slew rate (0.6 V/µs), wider offset (±1.5 mV), but same SOT-23-5 package and 1.8–6.0 V range | Acceptable for DC-coupled sensor buffers where speed is not critical | Select MCP6001T-E/OT only for cost-sensitive, low-bandwidth applications; TLV9051IDBVR required for >100-kHz signal paths |
Compared with OPA391DBVR and MCP6001T-E/OT, TLV9051IDBVR uniquely balances 15 V/µs slew rate, 2 pA input bias, integrated EMI filtering, and 330 µA quiescent current in a standard SOT-23-5 footprint-making it optimal for precision, high-speed, low-power industrial sensing.

FAQ
What is the maximum capacitive load the TLV9051IDBVR can drive while maintaining stability?
The TLV9051IDBVR is characterized to remain stable with capacitive loads up to 150 pF in unity-gain configuration. Its resistive open-loop output impedance simplifies compensation for larger loads, and phase margin remains ≥60° across this range per Figure 6-17 in the datasheet. For loads exceeding 150 pF, external series resistance at the output may be required.
Does the TLV9051IDBVR have shutdown functionality?
No, TLV9051IDBVR does not include shutdown capability. That feature is exclusive to the TLV9051S variant (e.g., TLV9051SIDBVR), which adds a sixth pin (SHDN) and reduces quiescent current to <1 µA in standby mode. TLV9051IDBVR operates continuously whenever powered.
Can TLV9051IDBVR operate from a single 1.8-V supply?
Yes, TLV9051IDBVR is fully specified for operation from 1.8 V to 6.0 V total supply voltage. At 1.8 V, it maintains rail-to-rail input/output swing, 106 dB open-loop gain, and 5-MHz gain bandwidth-enabling compatibility with modern ultra-low-power MCUs and battery-powered IoT sensors.
What is the input common-mode voltage range for TLV9051IDBVR?
The input common-mode voltage range for TLV9051IDBVR extends from (V−) − 0.1 V to (V+) + 0.1 V across the full supply range (1.8 V to 6.0 V). This rail-to-rail capability allows direct interfacing with sensors or DACs operating at either supply rail without external level-shifting circuitry.
Is TLV9051IDBVR suitable for driving ADC inputs in precision measurement systems?
Yes, TLV9051IDBVR is well-suited for driving SAR and delta-sigma ADC inputs. Its ±0.33 mV offset, 15 nV/√Hz noise at 10 kHz, and 0.75 µs 0.1% settling time (with 100-pF load) ensure minimal gain/offset error and fast acquisition-critical for 12- to 14-bit accuracy in systems like digital multimeters and process controllers.
