Product details
Overview
TLV9002IPWR 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, 27 nV/√Hz broadband noise, and 60 µA per channel quiescent current - enabling precision signal conditioning in space-constrained smoke detectors and wearable electronics.
For engineers reviewing the TLV9002IPWR datasheet, TLV9002IPWR pinout, TLV9002IPWR application, or TLV9002IPWR 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 compatibility with low-voltage single-supply designs.
Technical Context
The TLV9002IPWR uses scalable CMOS process technology to achieve low input bias current (5 pA) and rail-to-rail swing while maintaining unity-gain stability. Its resistive open-loop output impedance enables robust drive into high capacitive loads without external compensation.
This dual op-amp operates across 1.8 V–5.5 V supply rails and features no phase reversal during overdrive, internal EMI filtering, and shutdown capability in S-variants - though TLV9002IPWR itself is the standard non-shutdown version in 8-pin TSSOP package.
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 low-voltage industrial rails without level shifting. |
| Unity-Gain Bandwidth | 1 MHz - sufficient for sensor amplification, active filtering, and low-speed control loops up to ~100 kHz closed-loop. |
| Input Offset Voltage | ±0.4 mV - enables accurate DC-coupled amplification of microvolt-level sensor outputs without trimming. |
| Quiescent Current / Ch | 60 µA - allows battery operation for years in always-on smoke detectors or motion sensors. |
| Input Bias Current | 5 pA - minimizes voltage error across high-impedance sources like thermistors or photodiodes. |
| Capacitive Load Drive | 500 pF - eliminates need for isolation resistors when driving ADC inputs or long PCB traces. |
| Operating Temperature | –40°C to +125°C - qualified for automotive cabin modules, HVAC controllers, and industrial motor drives. |
Pinout & Package
TLV9002IPWR is packaged in an 8-pin TSSOP (PW) with body size 3.00 mm × 4.40 mm and exposed thermal pad connected to V–. Pin 1 is OUT1; pin 8 is V+.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT1 | Output of channel 1 - rail-to-rail swing supports full dynamic range utilization in single-supply systems. |
| 2 | IN1– | Inverting input, channel 1 - matched input impedance enables precision differential gain configurations. |
| 3 | IN1+ | Noninverting input, channel 1 - high-impedance node preserves signal integrity from high-Z sensors. |
| 4 | V– | Negative supply or ground reference - thermal pad must be soldered to PCB ground plane for thermal and EMI performance. |
| 5 | IN2+ | Noninverting input, channel 2 - independent channel allows dual-path signal conditioning (e.g., current + voltage sensing). |
| 6 | IN2– | Inverting input, channel 2 - symmetrical layout with IN1± simplifies PCB routing for matched trace lengths. |
| 7 | OUT2 | Output of channel 2 - identical AC/DC specs to OUT1 enable consistent performance across both channels. |
| 8 | V+ | Positive supply - decoupling capacitor (0.1 µF) required within 2 mm for stable high-frequency operation. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail I/O | Enables maximum signal swing from 0 V to VCC in single-supply systems - critical for low-voltage ADC interfacing. |
| Resistive open-loop output impedance | Reduces need for external series resistance when driving capacitive loads >500 pF - simplifies layout and improves transient response. |
| Integrated RFI/EMI filter | Rejects common-mode noise from switching power supplies and RF sources - improves immunity in noisy industrial environments. |
| Unity-gain stable | Eliminates risk of oscillation in buffer or gain-of-one configurations - removes requirement for external compensation networks. |
| Extended temperature range | Validated operation from –40°C to +125°C - supports placement near heat-generating components in motor control or HVAC modules. |
Applications
| Smoke Detectors | Wearable Devices |
|---|---|
Use Scenario: Amplifying weak ionization chamber or photoelectric sensor signals in battery-powered residential smoke alarms. IC Role / Device Role / Timing Role: Dual-channel signal conditioner - one channel for sensor baseline correction, second for filtered alarm threshold comparison. Use Value: 60 µA/ch quiescent current extends 10-year battery life; rail-to-rail output drives comparator inputs directly without level shifters. | Use Scenario: Conditioning biopotential signals (ECG, EMG) from dry electrodes in compact fitness trackers. IC Role / Device Role / Timing Role: Low-noise, low-offset front-end amplifier - first stage in analog signal chain before ADC sampling at ≤1 kSPS.

IC Role / Device Role / Timing Role: Dual-channel analog front-end - one channel for temperature linearization, second for humidity signal amplification. Use Value: Dual configuration reduces BOM count; rail-to-rail input accepts full 0–VCC thermistor divider range without clipping. |
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 package (3.91 mm × 4.90 mm) instead of TSSOP-8. | Less board area efficiency; higher thermal resistance than TSSOP; preferred for through-hole prototyping or legacy layouts. | Select TLV9002IDR only when SOIC footprint compatibility or manual soldering is required. |
| LMV358IDR | Higher quiescent current (150 µA/ch), lower GBW (1 MHz same), wider offset (±3 mV), no EMI filter. | Not suitable for ultra-low-power or high-EMI environments; acceptable for cost-driven consumer appliances where precision is secondary. | Choose LMV358IDR only if legacy design reuse or price sensitivity outweighs power/noise requirements. |
Compared with TLV9002IPWR, TLV9002IDR offers identical performance in a larger, more thermally robust package, while LMV358IDR trades precision and power efficiency for broader legacy support and lower unit cost - making TLV9002IPWR optimal for new space- and battery-constrained designs.

FAQ
What is the maximum capacitive load the TLV9002IPWR can drive without instability?
The TLV9002IPWR is characterized to drive up to 500 pF capacitively without external compensation, thanks to its resistive open-loop output impedance. This value is verified per TI's SBOS833R datasheet Section 7.10. For loads exceeding 500 pF, a small series resistor (e.g., 10–50 Ω) at the output is recommended. The TLV9002IPWR does not require additional phase compensation in standard gain configurations.
Does the TLV9002IPWR support single-supply operation down to 1.8 V?
Yes, the TLV9002IPWR is fully specified for single-supply operation from 1.8 V to 5.5 V, with rail-to-rail input and output swing maintained across this entire range. At 1.8 V, it retains ±0.4 mV input offset voltage, 1 MHz bandwidth, and 60 µA per channel quiescent current - enabling direct interface with low-voltage microcontrollers and ADCs without level-shifting circuitry.
Is the TLV9002IPWR pin-compatible with other dual op-amps in TSSOP-8 package?
No, the TLV9002IPWR has a non-standard pinout for dual op-amps: pin 1 = OUT1, pin 2 = IN1–, pin 3 = IN1+, pin 4 = V–, pin 5 = IN2+, pin 6 = IN2–, pin 7 = OUT2, pin 8 = V+. This differs from industry-standard dual op-amp pinouts (e.g., LM358, TLV2372), so PCB layout must follow TI's Figure 6-6 exactly - no drop-in replacement is possible without board revision.
What is the ESD rating of the TLV9002IPWR?
The TLV9002IPWR (non-S variant) has an HBM ESD rating of ±2000 V and CDM rating of ±1500 V, per JEDEC standards JS-001 and JESD22-C101. These ratings are confirmed in Section 7.2 of the SBOS833R datasheet. The device includes internal ESD protection diodes on all pins, but external TVS devices are still recommended in high-static environments like HVAC service panels.
Can the TLV9002IPWR be used in automotive applications?
The TLV9002IPWR is qualified for operation from –40°C to +125°C and meets AEC-Q200 stress test requirements for passive components, but it is not AEC-Q100 qualified as an integrated circuit. It is suitable for under-hood-adjacent applications (e.g., HVAC actuators, cabin air quality sensors) where ambient temperature stays within spec, but not for safety-critical ADAS or powertrain control without additional system-level validation.
