Product details
Overview
TLV9051IDPWR from Texas Instruments is a single-channel, rail-to-rail input/output operational amplifier optimized for low-voltage, high-speed signal conditioning. It delivers 5 MHz unity-gain bandwidth, 15 V/µs slew rate, ±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 TLV9051IDPWR datasheet, TLV9051IDPWR pinout, TLV9051IDPWR application, or TLV9051IDPWR equivalent, key selection criteria include its 15 V/µs slew rate under 100 pF load, rail-to-rail output swing within 16 mV of rails (at 5.5 V, 10 kΩ), 15 nV/√Hz input voltage noise at 10 kHz, –40°C to +125°C extended temperature range, and SOT-23-5 (DBV) package compatibility with space-constrained industrial and consumer PCB layouts.
Technical Context
The TLV9051IDPWR employs a CMOS input stage enabling ultra-low input bias current (2 pA typical) and rail-to-rail common-mode input range (V– – 0.1 V to V+ + 0.1 V). Its internal RFI/EMI filter and phase-reversal immunity ensure robust operation in noisy environments without external protection circuitry.
Designed for unity-gain stability, it drives capacitive loads up to 150 pF while maintaining ≥60° phase margin. Its open-loop output impedance (~250 Ω at 5 MHz) simplifies compensation with higher capacitive loads, and its 0.75 µs 0.1% settling time (2-V step, 100 pF) supports fast transient response in closed-loop configurations.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Unity-gain bandwidth | 5 MHz - enables stable gain-of-1 operation with minimal phase lag up to audio and low-MHz signal frequencies. |
| Slew rate | 15 V/µs - supports clean 2-V step response in ≤0.75 µs (0.1% settling), critical for pulse amplification and fast feedback loops. |
| Input offset voltage | ±0.33 mV (typ) - ensures <1 LSB error in 12-bit ADC front-ends operating at 5 V full-scale. |
| Quiescent current | 330 µA - allows battery-powered designs (e.g., portable sensors) to achieve >1-year runtime on coin cells. |
| Rail-to-rail I/O | Input: V– – 0.1 V to V+ + 0.1 V; Output: within 16 mV of rails (5.5 V, 10 kΩ) - maximizes dynamic range in single-supply systems. |
| Input voltage noise | 15 nV/√Hz @ 10 kHz - preserves SNR in photodiode and strain gauge amplifiers with bandwidths up to 100 kHz. |
| Operating temperature | –40°C to +125°C - qualified for under-hood automotive, HVAC control, and industrial motor drive monitoring. |
Pinout & Package
TLV9051IDPWR is packaged in a 5-pin SOT-23 (DBV) case measuring 2.9 mm × 2.8 mm, with exposed pad not present. The package supports reflow soldering per JEDEC J-STD-020 and is rated for moisture sensitivity level 1.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT | Amplifier output - drives loads up to ±50 mA short-circuit current; rail-to-rail swing enables full utilization of ADC input range. |
| 2 | V– | Negative supply or ground reference - must be connected directly to low-impedance ground plane to minimize noise coupling and ensure CMRR >80 dB. |
| 3 | IN+ | Noninverting input - high-impedance CMOS node (2 pA bias current); requires guard ring in high-Z sensor interfaces. |
| 4 | IN– | Inverting input - forms feedback node; layout symmetry with IN+ minimizes offset drift due to thermal gradients. |
| 5 | V+ | Positive supply - accepts 1.8 V to 6.0 V; decoupling capacitor (0.1 µF ceramic) required within 2 mm of this pin for stability. |
Key Features
| Feature | Design Value |
|---|---|
| Internal RFI/EMI filter | Rejects >30 dB of 100 MHz–2 GHz interference without external ferrite beads or RC filters. |
| No phase reversal on overdrive | Prevents latch-up and system instability when inputs exceed supply rails - eliminates need for external clamping diodes. |
| Low broadband noise | 15 nV/√Hz at 10 kHz enables sub-10 µV RMS noise floor in 10 kHz bandwidth applications (e.g., precision current shunt monitoring). |
| Capacitive-load drive | Stable with ≥150 pF load - supports direct connection to long traces, LCD bias lines, or unbuffered ADC inputs without isolation resistors. |
| Extended temperature range | Specified performance from –40°C to +125°C - validated for continuous operation in sealed enclosures without derating. |
Applications
| Photodiode Amplifier | Low-Side Current Sensing |

Equivalent & Alternatives
The following parts are listed as comparable options for similar op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA391DBVR | Higher 10 MHz GBW and 21 V/µs slew rate; 570 µA IQ; no EMI filter. | Better for >1 MHz closed-loop bandwidth needs; less suitable for noisy industrial environments without added filtering. | Choose OPA391DBVR when bandwidth >5 MHz is required and board-level EMI mitigation is already implemented. |
| MCP6001T-E/OT | 1 MHz GBW, 0.6 V/µs slew rate, 100 µA IQ, rail-to-rail I/O, no EMI filter. | Optimized for ultra-low-power, low-bandwidth sensor buffering; lacks speed/noise performance for fast current sensing. | Choose MCP6001T-E/OT only for sub-100 kHz applications where quiescent current <150 µA is mandatory. |
Compared with TLV9051IDPWR, OPA391DBVR trades higher power for greater speed and bandwidth, while MCP6001T-E/OT sacrifices speed and noise performance to achieve ultra-low IQ - making TLV9051IDPWR the balanced choice for 1–5 MHz, low-noise, low-voltage industrial signal chains.

FAQ
What is the maximum capacitive load TLV9051IDPWR can drive while remaining stable?
The TLV9051IDPWR is characterized for stable operation with up to 150 pF capacitive load, maintaining ≥60° phase margin and <5% overshoot in unity-gain configuration. Driving >150 pF requires external series resistance (typically 10–50 Ω) at the output to isolate the capacitance and preserve stability - confirmed by Figure 6-17 and 6-19 in the SBOS942J datasheet.
Does TLV9051IDPWR support true rail-to-rail input common-mode range?
Yes. TLV9051IDPWR supports a common-mode input voltage range from (V–) – 0.1 V to (V+) + 0.1 V across the full supply range (1.8 V to 6.0 V), verified per Section 6.7 of SBOS942J. This enables direct interface with sensors referenced to ground or V+ in single-supply systems without level-shifting circuitry.
What is the typical input offset voltage drift of TLV9051IDPWR over temperature?
The typical input offset voltage drift of TLV9051IDPWR is ±0.5 µV/°C over –40°C to +125°C, as specified in the "dVOS/dT" parameter of Section 6.7. This low drift ensures minimal calibration drift in temperature-varying environments such as HVAC control or motor drive feedback circuits.
Can TLV9051IDPWR operate from a 1.8 V single supply?
Yes. TLV9051IDPWR is fully specified for operation from 1.8 V to 6.0 V total supply voltage (V+ – V–), including rail-to-rail input/output functionality and 330 µA quiescent current at 1.8 V. Its 5 MHz bandwidth and 15 V/µs slew rate remain functional at minimum supply, enabling direct integration with Li-ion or energy-harvesting power sources.
Is TLV9051IDPWR pin-compatible with other members of the TLV905x family?
No. TLV9051IDPWR (single, 5-pin SOT-23) is not pin-compatible with TLV9052 (dual, 8-pin) or TLV9054 (quad, 14/16-pin) variants. Pin count, pinout, and package footprints differ across channel counts - e.g., TLV9051 uses pins 1–5 for OUT, V–, IN+, IN–, V+, while TLV9052 allocates separate IN/OUT pairs per channel in an 8-pin layout.
