Product details
Overview
TLV9061IDPWR from Texas Instruments is a single-channel, rail-to-rail input/output CMOS operational amplifier optimized for cost-sensitive, low-voltage systems. It delivers 10MHz unity-gain bandwidth, ±0.3mV typical input offset voltage, 10nV/√Hz input voltage noise, 538µA quiescent current, and operates from 1.8V to 5.5V supply. It is used in low-side current sensing and wearable device signal conditioning where precision, low power, and small footprint are critical.
For engineers reviewing the TLV9061IDPWR datasheet, TLV9061IDPWR pinout, TLV9061IDPWR application, or TLV9061IDPWR equivalent, this page provides verified electrical specifications, SOT-23-5 package details, real-world use scenarios in HVAC and e-bikes, and two validated alternative op-amps with documented functional differences.
Technical Context
The TLV9061IDPWR employs a CMOS input stage enabling ultra-low input bias current (0.5pA) and rail-to-rail common-mode input range extending 0.1V beyond both rails. Its resistive open-loop output impedance simplifies stability with capacitive loads up to 100pF and improves robustness against phase reversal during overdrive.
This op-amp is unity-gain stable and integrates internal RFI/EMI filtering. It is specified across –40°C to +125°C and supports single-supply operation down to 1.8V, making it suitable for battery-powered industrial and consumer end equipment requiring high DC accuracy and dynamic performance.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Unity-gain bandwidth | 10MHz - enables accurate amplification of signals up to ~1MHz at G = +10 without significant gain roll-off. |
| Input offset voltage | ±0.3mV (typ) - ensures ≤0.06% error in 0.5V full-scale current-sense applications at room temperature. |
| Quiescent current | 538µA per amplifier - allows continuous operation in always-on wearable sensors powered by coin cells. |
| Supply voltage range | 1.8V to 5.5V - supports direct interface with Li-ion, LiPo, and 3.3V/5V logic domains without level shifting. |
| Input voltage noise | 10nV/√Hz at 10kHz - preserves SNR in audio preamps and sensor front-ends with bandwidths under 20kHz. |
| Open-loop output impedance | 100Ω (resistive, f = 10MHz) - reduces peaking and overshoot when driving ≥100pF loads, easing PCB layout. |
| CMRR | 80–103dB (TA = –40°C to +125°C) - maintains accuracy in noisy motor-control environments with varying common-mode transients. |
Pinout & Package
TLV9061IDPWR is packaged in a 5-pin SOT-23 (DBV) package measuring 2.90mm × 1.60mm, optimized for space-constrained PCB layouts in portable and embedded systems.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

| 2 | V− | Negative supply or ground reference; accepts 0V in single-supply mode and supports true rail-to-rail input common-mode range. |
| 3 | IN+ | Noninverting input; high-impedance CMOS node (0.5pA bias) minimizes loading on high-Z sources like thermistors or bridge sensors. |
| 4 | IN− | Inverting input; matched to IN+ for low offset drift; used in transimpedance or differential configurations. |
| 5 | V+ | Positive supply input; accepts up to 5.5V; internal ESD protection rated to ±2500V HBM per pin. |
Key Features
| Feature | Design Value |

Equivalent & Alternatives
The following parts are listed as comparable options for similar operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA316IDBVR | Higher 10MHz GBW but higher 1.2mV max VOS and 400µA IQ; no integrated RFI filter. | Better for wideband AC-coupled signal chains; less suited for DC-critical low-side sensing. | Select OPA316IDBVR only if bandwidth >10MHz is required and offset budget allows ±1.2mV. |
| TLV9001IDBVR | Lower 1MHz GBW, 1.6mV max VOS, and 50µA IQ; same SOT-23-5 package and rail-to-rail I/O. | Optimized for ultra-low-power always-on monitoring; insufficient for fast current-sense transient response. | Choose TLV9001IDBVR when quiescent current <100µA is mandatory and bandwidth ≤1MHz suffices. |
Compared with OPA316IDBVR and TLV9001IDBVR, TLV9061IDPWR uniquely balances 10MHz bandwidth, sub-millivolt offset, and integrated EMI rejection-making it optimal for cost-sensitive, mixed-signal industrial and portable systems demanding both precision and robustness.

FAQ
What is the maximum capacitive load the TLV9061IDPWR can drive stably?
The TLV9061IDPWR is characterized for stable operation with up to 100pF capacitive load. Its resistive open-loop output impedance (100Ω at 10MHz) significantly reduces peaking and overshoot compared to conventional op-amps, allowing reliable use with larger loads in many practical layouts-though full stability verification is recommended for loads exceeding 100pF in production designs.
Does the TLV9061IDPWR have a shutdown pin?
No, the TLV9061IDPWR does not include a shutdown function. That feature is present only in the TLV9061S variants (e.g., TLV9061SIDBVR), which add a sixth pin (SHDN) and reduce quiescent current to <1.5µA in standby. The TLV9061IDPWR operates continuously whenever powered within its 1.8V–5.5V supply range.
Is the TLV9061IDPWR suitable for single-supply 3.3V operation?
Yes, the TLV9061IDPWR is fully specified for 3.3V single-supply operation. Its rail-to-rail input extends 0.1V beyond both rails (–0.1V to 3.4V), and its output swings within 20mV of each rail under 10kΩ load-enabling direct interfacing with 3.3V ADCs and microcontrollers without level-shifting circuitry.
What is the input bias current specification for TLV9061IDPWR at 85°C?
At 85°C, the TLV9061IDPWR maintains an input bias current of ≤1.5pA (max), per the datasheet's TA = –40°C to +125°C characterization. This ultra-low, temperature-stable bias current ensures minimal error in high-impedance sensor interfaces such as pH probes or photodiode transimpedance amplifiers across extended thermal conditions.
How does the TLV9061IDPWR's EMI rejection compare to standard op-amps?
The TLV9061IDPWR integrates an internal RFI/EMI filter that attenuates high-frequency interference (e.g., from DC/DC converters or radio transceivers) without requiring external RC networks. This is confirmed in TI's application testing-reducing susceptibility to 900MHz GSM bursts by >20dB compared to non-filtered equivalents like the TLV2461, directly improving signal integrity in noisy environments.
