Product details
Overview
TLV9001IDPWR from Texas Instruments is a single-channel, rail-to-rail input/output operational amplifier optimized for low-cost, space-constrained systems operating from 1.8 V to 5.5 V supply. It delivers ±0.4 mV input offset voltage, 1 MHz unity-gain bandwidth, 60 µA quiescent current per channel, and stable operation into 500 pF capacitive loads-enabling precision sensor signal conditioning in wearable devices and smoke detectors.
For engineers reviewing the TLV9001IDPWR datasheet, TLV9001IDPWR pinout, TLV9001IDPWR application, or TLV9001IDPWR equivalent, key selection criteria include its resistive open-loop output impedance (simplifying stabilization with high capacitive loads), integrated RFI/EMI filter, –40°C to 125°C extended temperature range, and compatibility with low-voltage battery-powered designs requiring rail-to-rail swing and sub-1 µA shutdown current in variant TLV9001S.
Technical Context
The TLV9001IDPWR uses scalable CMOS process technology to achieve ultra-low quiescent current while maintaining rail-to-rail input and output swing across its full 1.8 V–5.5 V supply range. Its internal architecture features unity-gain stability without external compensation and an integrated RFI/EMI rejection filter that suppresses high-frequency interference before amplification.
Unlike conventional op amps, the TLV9001IDPWR exhibits resistive open-loop output impedance-enabling robust closed-loop performance even with >500 pF capacitive loads-and includes no-phase-reversal behavior during overdrive, eliminating output latch-up in transient conditions common in sensor front-ends and current-sense circuits.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.8 V to 5.5 V - supports single-cell Li-ion, coin-cell, and 3.3 V/5 V system rails without level-shifting. |
| Unity-Gain Bandwidth | 1 MHz - enables stable amplification of DC–100 kHz signals (e.g., thermistor, RTD, or piezoelectric sensor outputs) with minimal phase lag. |
| Input Offset Voltage | ±0.4 mV - ensures ≤0.08% gain error at 5 V output span, critical for 12-bit ADC interfacing in EPOS and HVAC control. |
| Quiescent Current | 60 µA per channel - allows continuous operation for >1 year on a 220 mAh coin cell in motion detectors or smoke alarms. |
| Capacitive Load Drive | 500 pF - eliminates need for isolation resistors when driving long PCB traces or ADC input capacitance (e.g., SAR ADCs with 10–20 pF CIN). |
| Input Bias Current | 5 pA - minimizes voltage error across high-impedance sources (e.g., pH electrodes or photodiode transimpedance feedback networks). |
| Operating Temperature | –40°C to +125°C - qualified for under-hood automotive modules, industrial motor controllers, and outdoor HVAC sensors. |
Pinout & Package
TLV9001IDPWR is packaged in a 5-pin SOT-23 (DBV) package measuring 1.60 mm × 2.90 mm, with exposed pad option not included. The device uses standard SOT-23 pinout alignment compatible with automated placement and reflow processes.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OUT) | Amplifier output | Delivers rail-to-rail swing; drives ADC inputs, filters, or low-side current sense shunts directly. |
| 2 (V–) | Negative supply / ground reference | Accepts ground or negative rail; supports true single-supply operation down to 1.8 V total supply. |
| 3 (IN+) | Noninverting input | High-impedance node (5 pA bias); connects to sensor bridges, thermistors, or reference dividers. |
| 4 (IN–) | Inverting input | High-impedance node; used for feedback in transimpedance, differential, or inverting configurations. |
| 5 (V+) | Positive supply | Accepts up to 5.5 V; internal regulation ensures consistent 1 MHz bandwidth across full supply range. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail I/O | Enables full dynamic range utilization in 1.8 V systems-output swings within 10 mV of rails, preserving SNR in low-voltage ADC interfaces. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV9001IDBVR | Same electrical specs; SC70-5 (DCK) package (1.25 mm × 2.00 mm), 0.65 mm pitch - 23% smaller footprint than SOT-23. | Better suited for ultra-dense layouts (e.g., barcode scanner PCBs) where board area is constrained. | Select TLV9001IDBVR when minimizing PCB real estate is prioritized over thermal dissipation or legacy SOT-23 tooling compatibility. |
| LMV321IDBVR | Higher quiescent current (130 µA), lower bandwidth (1.4 MHz), no integrated RFI filter, and ±1.6 mV offset - less precision and higher power. | Acceptable for cost-sensitive, non-battery-powered applications like appliance control panels where EMI immunity is secondary. | Choose LMV321IDBVR only if legacy design reuse or distributor stock availability outweighs the TLV9001IDPWR's 58% lower IQ and superior noise/EMI performance. |
Compared with TLV9001IDBVR, TLV9001IDPWR offers larger SOT-23 pads for improved manufacturability and thermal relief but requires slightly more board area; versus LMV321IDBVR, TLV9001IDPWR delivers twice the precision (±0.4 mV vs ±1.6 mV offset), half the supply current, and certified RFI rejection-making it the preferred choice for battery-powered, safety-critical, or EMI-prone environments.

FAQ
What is the maximum capacitive load the TLV9001IDPWR can drive without external compensation?
The TLV9001IDPWR is specified to drive up to 500 pF capacitive load while maintaining stability, thanks to its resistive open-loop output impedance. This eliminates the need for isolation resistors in typical ADC interface or filter applications. For loads exceeding 500 pF, TI recommends verifying phase margin in the target circuit; the TLV9001IDPWR remains easier to stabilize than conventional op amps due to its inherent output impedance profile.
Does the TLV9001IDPWR support true single-supply operation down to 1.8 V?
Yes, the TLV9001IDPWR operates from a total supply voltage of 1.8 V to 5.5 V, with rail-to-rail input and output swing across this entire range. When V– is connected to ground, the device functions as a true single-supply amplifier-accepting input signals from 0 V to V+, and delivering output from 0 V to V+, enabling direct interfacing with low-voltage microcontrollers and ADCs without level-shifting circuitry.
What is the input offset voltage specification for TLV9001IDPWR, and how does it impact precision sensing?
The TLV9001IDPWR has a maximum input offset voltage of ±0.4 mV at room temperature. In a 5 V full-scale system, this introduces ≤0.008% gain error-equivalent to <1 LSB error in a 12-bit ADC with 5 V reference. This level of precision supports accurate temperature measurement with NTC thermistors, current sensing with 10 mΩ shunts, and bridge-based pressure transducers without factory trimming or software calibration.
Is the TLV9001IDPWR pin-compatible with other op amps in the TLV900x family?
No-TLV9001IDPWR (5-pin SOT-23) is not pin-compatible with TLV9001S variants (6-pin SOT-23/SC70) or multi-channel TLV9002/TLV9004 devices. Pin count, pinout order, and function differ: TLV9001IDPWR has no shutdown pin, while TLV9001S adds SHDN on pin 5. Substituting requires PCB layout revision; however, electrical characteristics and package footprints (e.g., SOT-23) are consistent across same-form-factor TLV900x members.
How does the integrated RFI/EMI filter in TLV9001IDPWR improve system reliability?
The integrated RFI/EMI filter in TLV9001IDPWR attenuates high-frequency noise (100 MHz–2 GHz) before amplification, reducing susceptibility to interference from nearby switching regulators, Bluetooth/Wi-Fi modules, or motor drivers. This prevents erroneous output saturation or false triggers in safety-critical applications like smoke detectors and motion sensors-eliminating the need for external ferrite beads or RC filters and simplifying layout validation.
