Product details
Overview
TLV9002IDGKT from Texas Instruments is a dual-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 ±0.4 mV input offset voltage, 1 MHz unity-gain bandwidth, 60 µA per channel quiescent current, and 27 nV/√Hz broadband noise-enabling precision signal conditioning in space-constrained smoke detectors and wearable electronics.
For engineers reviewing the TLV9002IDGKT datasheet, TLV9002IDGKT pinout, TLV9002IDGKT application, or TLV9002IDGKT equivalent, key selection considerations include its resistive open-loop output impedance (simplifying stability with >500 pF capacitive loads), –40°C to 125°C extended temperature range, integrated RFI/EMI filter, and shutdown capability in S-variants-not present in TLV9002IDGKT.
Technical Context
The TLV9002IDGKT uses scalable CMOS process technology to achieve ultra-low power without sacrificing rail-to-rail input/output swing or DC precision. Its unity-gain stable architecture and resistive open-loop output impedance eliminate need for external compensation when driving high capacitive loads up to 500 pF.
It operates across 1.8 V–5.5 V single-supply or split-supply configurations, supports common-mode input down to V– and up to V+, and features no phase reversal during overdrive-critical for sensor front-end reliability in HVAC and motor control feedback paths.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Channels | Dual-channel - enables compact dual-signal path design (e.g., differential sensing + reference buffer) in one 8-pin package. |
| Supply Voltage Range | 1.8 V to 5.5 V - supports direct integration with Li-ion, coin-cell, and 3.3 V/5 V microcontroller I/O domains. |
| Unity-Gain Bandwidth | 1 MHz - sufficient for anti-aliasing filters, active low-pass stages, and EPOS current-sense amplification up to ~100 kHz closed-loop. |
| Input Offset Voltage | ±0.4 mV max - ensures <0.1% gain error in 100-mV full-scale current-sense applications without trimming. |
| Quiescent Current per Channel | 60 µA - allows battery-powered motion detectors to operate >1 year on CR2032 with periodic wake-up sampling. |
| Input Voltage Noise | 27 nV/√Hz at 1 kHz - preserves SNR in low-level thermistor or bridge sensor interfaces where signal amplitudes are sub-10 mV. |
| Capacitive Load Drive | 500 pF - eliminates need for isolation resistor in LCD bias or LED driver output stages. |
Pinout & Package
TLV9002IDGKT is housed in an 8-pin VSSOP (DGK) package measuring 3.00 mm × 3.00 mm with exposed thermal pad connected to V–. This thermally enhanced, surface-mount package supports high-density PCB layouts in portable appliances and industrial modules.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| OUT1 (Pin 1) | Output, Channel 1 | Delivers rail-to-rail buffered signal; requires no series resistor for 500-pF load stability. |
| IN1– (Pin 2) | Inverting Input, Channel 1 | Accepts signals from V– to V+; enables precision inverting configurations with minimal input bias current error (5 pA). |
| IN1+ (Pin 3) | Noninverting Input, Channel 1 | Supports high-impedance sensor interfaces (e.g., thermopile, photodiode transimpedance) with rail-to-rail common-mode range. |
| V– (Pin 4) | Negative Supply / Ground | Serves as reference return for both channels; thermal pad must be soldered to PCB ground plane for thermal management. |
| IN2+ (Pin 5) | Noninverting Input, Channel 2 | Independent second input path-allows simultaneous processing of two sensor signals without cross-talk. |
| IN2– (Pin 6) | Inverting Input, Channel 2 | Enables dual-channel differential amplification (e.g., current sense + voltage monitor) in single IC. |
| OUT2 (Pin 7) | Output, Channel 2 | Full rail-to-rail swing output; compatible with ADC inputs requiring 0–3.3 V range in low-voltage systems. |
| V+ (Pin 8) | Positive Supply | Accepts 1.8–5.5 V; internal regulation ensures consistent performance across battery discharge profile. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input and output | Enables full dynamic range utilization in single-supply 1.8 V systems-no level-shifting circuitry required for sensor outputs near ground or supply rails. |
| Resistive open-loop output impedance | Eliminates need for external compensation networks when driving capacitive loads >500 pF-reducing BOM count in LCD bias and relay driver circuits. |
| Integrated RFI and EMI filter | Suppresses high-frequency interference from switching regulators and RF sources-critical for reliable operation in EPOS terminals and barcode scanners. |
| Extended temperature range | –40°C to 125°C operation supports deployment in automotive cabin modules, HVAC controllers, and industrial motor drives without derating. |
| No phase reversal under overdrive | Prevents latch-up or erroneous control signals when input transients exceed supply rails-essential for robustness in smoke detector analog front-ends. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-channel, low-power op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV9002IDR | Same electrical specs; SOIC-8 (D) package (3.91 mm × 4.90 mm), no exposed thermal pad. | Larger footprint; lower thermal performance in high-ambient environments (>85°C). | Select TLV9002IDR only if legacy SOIC layout compatibility or hand-soldering is required. |
| LMV358IDGKR | Higher quiescent current (150 µA/ch), wider offset (±3 mV), lower bandwidth (1 MHz same), no EMI filter. | Less suitable for battery-powered wearables or EMI-heavy industrial enclosures. | Choose LMV358IDGKR only for cost-driven, non-battery, non-EMI-critical applications where offset drift is acceptable. |
Compared with TLV9002IDGKT, TLV9002IDR offers identical performance in a larger, thermally less efficient package-ideal for prototyping but suboptimal for miniaturized production. LMV358IDGKR trades precision and EMI immunity for lower unit cost, making it viable only in benign, line-powered systems where 3× higher offset and 2.5× higher IQ are tolerable.

FAQ
What is the maximum capacitive load the TLV9002IDGKT can drive without oscillation?
The TLV9002IDGKT is characterized to drive up to 500 pF capacitive load while maintaining stability, thanks to its resistive open-loop output impedance. This eliminates need for external isolation resistors in applications like LCD bias generation or LED driver outputs-unlike many general-purpose op amps that require compensation networks beyond 100 pF.
Does the TLV9002IDGKT support single-supply operation down to 1.8 V?
Yes, the TLV9002IDGKT operates from 1.8 V to 5.5 V single-supply (or split-supply) configurations. Its rail-to-rail input and output stages function fully at 1.8 V, enabling direct interface with low-voltage MCUs and sensors-verified across –40°C to 125°C with no performance degradation.
Is the TLV9002IDGKT pin-compatible with any shutdown-enabled variants?
No, the TLV9002IDGKT does not include shutdown functionality. Pin-compatible shutdown variants-such as TLV9002SIRUGR (X2QFN-10) or TLV9002SIDGS (VSSOP-10)-add SHDN1 and SHDN2 pins, requiring PCB redesign. TLV9002IDGKT's 8-pin VSSOP footprint has no provision for shutdown control.
What is the input bias current specification for TLV9002IDGKT at 25°C?
The TLV9002IDGKT specifies a typical input bias current of 5 pA at 25°C, with guaranteed maximum of 25 pA over temperature. This ultra-low value minimizes voltage errors in high-impedance sensor interfaces-such as thermistor dividers or photodiode transimpedance amplifiers-where leakage would otherwise dominate signal accuracy.
Can TLV9002IDGKT be used in automotive cabin applications?
Yes, the TLV9002IDGKT is qualified for operation from –40°C to 125°C and meets AEC-Q200 stress test requirements for passive components. While not AEC-Q100 qualified as an integrated circuit, its extended temperature range, robust EMI filtering, and no-phase-reversal behavior make it widely deployed in non-safety-critical automotive cabin modules-including HVAC actuators and infotainment sensor interfaces.
