Product details
Overview
TLV9001IDCKR from Texas Instruments is a single-channel, rail-to-rail input/output operational amplifier optimized for low-power, cost-sensitive systems operating from 1.8 V to 5.5 V supply. It delivers 1 MHz unity-gain bandwidth, ±0.4 mV input offset voltage, 60 µA quiescent current per channel, and 27 nV/√Hz broadband noise-enabling precision signal conditioning in space-constrained wearable devices and smoke detectors.
For engineers reviewing the TLV9001IDCKR datasheet, TLV9001IDCKR pinout, TLV9001IDCKR application, or TLV9001IDCKR equivalent, key selection criteria include its resistive open-loop output impedance (simplifying stabilization with >500 pF capacitive loads), –40°C to 125°C extended temperature range, integrated RFI/EMI filter, and SC70-5 (DCK) package footprint compatibility with high-density PCB layouts.
Technical Context
The TLV9001IDCKR employs a scalable CMOS process optimized for low-voltage operation and robust overdrive recovery without phase reversal. Its rail-to-rail input stage supports common-mode voltages from V– to V+, while the rail-to-rail output delivers full-swing capability across the entire supply range.
Designed for unity-gain stability, the device features an internal resistive open-loop output impedance that enables stable operation into ≥500 pF capacitive loads-eliminating need for external isolation resistors in sensor interface and active filter applications where drive strength and phase margin are critical.
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 energy-harvesting power rails |
| Unity-Gain Bandwidth | 1 MHz - sufficient for DC–100 kHz sensor signal amplification and anti-aliasing filtering |
| Input Offset Voltage | ±0.4 mV - enables <1% error in 100-mV full-scale current sensing without trimming |
| Quiescent Current | 60 µA/ch - allows continuous operation in battery-powered wearables for >1 year on CR2032 |
| Input Bias Current | 5 pA - preserves accuracy in high-impedance pH, thermopile, or photodiode interfaces |
| Capacitive Load Drive | ≥500 pF - eliminates need for series output resistor in LCD bias or piezo driver circuits |
| RFI/EMI Rejection | Integrated filter - suppresses GSM/ISM-band interference in consumer electronics without external RC networks |
Pinout & Package
TLV9001IDCKR is packaged in a 5-pin SC70 (DCK) package measuring 1.25 mm × 2.00 mm, optimized for high-density portable designs. The package uses JEDEC-standard SC70 pinout with exposed pad not present.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | IN+ | Noninverting input - accepts signals up to V+ or down to V–, enabling true rail-to-rail common-mode range |
| 2 | V– | Negative supply or ground reference - supports single-supply operation with 0 V as return path |
| 3 | IN– | Inverting input - forms feedback node for transimpedance or differential configurations |
| 4 | OUT | Amplified output - delivers rail-to-rail swing with <100 Ω effective open-loop output resistance |
| 5 | V+ | Positive supply - powers internal bias circuitry and sets output compliance limits |

Equivalent & Alternatives
The following parts are listed as comparable options for similar operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LMV321IDBVR | Higher 1.4 MHz GBW but 130 µA IQ; no integrated RFI filter; ±1.5 mV Vos | Better bandwidth for fast-settling filters; less suitable for ultra-low-power or EMI-prone environments | Select when higher speed outweighs battery life and noise immunity requirements |
| TLV2401CDBVR | Lower 20 µA IQ but only 200 kHz GBW; ±1.5 mV Vos; no RFI filter; 1.8–6 V supply | Superior battery longevity in static sensor nodes; insufficient for audio or active filter use cases | Select for multi-year coin-cell deployments where bandwidth <200 kHz is acceptable |
Compared with LMV321IDBVR and TLV2401CDBVR, TLV9001IDCKR uniquely balances 1 MHz bandwidth, 60 µA quiescent current, ±0.4 mV offset, and integrated RFI rejection-making it optimal for cost-sensitive, battery-powered sensor front-ends requiring both precision and noise resilience.

FAQ
What is the maximum capacitive load the TLV9001IDCKR can drive stably?
The TLV9001IDCKR is characterized to drive ≥500 pF capacitive loads without external compensation, thanks to its resistive open-loop output impedance. This eliminates the need for series isolation resistors in LCD bias, piezo actuator, or cable-driving applications-reducing BOM count and layout complexity while maintaining phase margin above 45°.
Does the TLV9001IDCKR support single-supply operation?
Yes, the TLV9001IDCKR fully supports single-supply operation from 1.8 V to 5.5 V. Its rail-to-rail input stage accepts common-mode voltages from V– (ground) to V+, and its rail-to-rail output swings within 10 mV of each rail-enabling direct interfacing with 1.8-V ADCs and microcontrollers without level-shifting circuitry.
Is the TLV9001IDCKR pin-compatible with other SC70-5 op amps?
No, TLV9001IDCKR uses the standard SC70-5 pinout (IN+, V–, IN–, OUT, V+) defined in TI's documentation, but it is not pin-compatible with legacy SC70-5 op amps like the OPA348 or MCP6001 due to differing pin assignments (e.g., V– and IN– positions). Always verify pin functions against the official TLV9001IDCKR datasheet before board reuse.
What is the ESD rating of the TLV9001IDCKR?
The TLV9001IDCKR has HBM ESD rating of ±2000 V and CDM rating of ±1500 V, per JEDEC standards. These ratings apply to all packages except TLV9002S variants. The robust ESD protection reduces risk of field failures during handling and assembly in high-volume manufacturing environments.
Can the TLV9001IDCKR be used in automotive applications?
The TLV9001IDCKR is qualified for operation from –40°C to +125°C and meets AEC-Q200 stress test requirements for temperature cycling and humidity exposure. However, it is not AEC-Q100 qualified; for automotive safety-critical subsystems, TI recommends the TLV9001-Q1 variant, which includes additional qualification testing and PPAP documentation.
