Product details
Overview
TLV2322PWLE from Texas Instruments is a dual, low-voltage, rail-to-rail output operational amplifier optimized for single-supply operation in battery-powered sensor signal conditioning. It delivers 27 µA max supply current per channel at –40°C to +85°C, 9 mV max input offset voltage at 25°C, and operates from 2.7 V to 8 V supply. It is used in smoke detectors, pressure transmitters, and motion sensors where ultra-low power and ground-sensing capability are critical.
For engineers reviewing the TLV2322PWLE datasheet, TLV2322PWLE pinout, TLV2322PWLE application, or TLV2322PWLE equivalent, this page provides verified electrical specs, TSSOP-8 package details, real-world use cases in field transmitters and safety sensors, and two validated alternative op-amps with documented functional trade-offs.
Technical Context
The TLV2322PWLE uses Texas Instruments' LinCMOS™ silicon-gate process to achieve ultra-low input bias current (0.6 pA typ at 25°C) and high input impedance (10¹² Ω). Its input common-mode range extends to the negative rail and up to VDD – 1 V at 25°C, enabling true single-supply interfacing with grounded sensors.
It features rail-to-rail output swing (VOL = 115 mV typ at 1 mA load, VOH = 1.75 V min at 3 V supply), unity-gain bandwidth of 27 kHz at 3 V (85 kHz at 5 V), and phase margin of 34° at 25°C - all specified across –40°C to +85°C with no derating required.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7 V to 8 V - supports direct connection to 3 V and 5 V logic rails without regulation. |
| Supply Current per Channel | 27 µA max over –40°C to +85°C - enables multi-year battery life in portable sensor nodes. |
| Input Offset Voltage | 9 mV max at 25°C - ensures <1% error in 1 V full-scale analog front-ends without trimming. |
| Input Bias Current | 0.6 pA typ at 25°C - preserves signal integrity when amplifying high-impedance sources (e.g., piezoresistive sensors). |
| Common-Mode Input Range | Extends to negative rail and up to VDD – 1 V at 25°C - allows direct DC-coupled sensing of 0 V–referenced transducers. |
| Output Voltage Swing | Rail-to-rail: VOL ≤ 150 mV, VOH ≥ VDD – 1.2 V at 1 mA - maximizes dynamic range in 3 V systems. |
| Unity-Gain Bandwidth | 27 kHz at 3 V, 85 kHz at 5 V - sufficient for slow-varying industrial sensor signals (e.g., temperature, pressure). |
Pinout & Package
PW package: 8-pin Thin-Shrink Small-Outline Package (TSSOP), 3.0 mm × 4.4 mm × 1.1 mm height, surface-mount, lead-free and RoHS compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

| Rail-to-rail output | Swings within 150 mV of GND and within 1.2 V of VDD - preserves >90% of 3 V supply headroom for signal fidelity. |
| Ground-sensing input | Common-mode range includes GND and extends to VDD – 1 V - enables direct interface with 0 V–referenced bridge sensors. |
| ESD protection | 2000 V HBM per MIL-STD-883C Method 3015.2 - reduces board-level transient protection requirements in field-deployed equipment. |
| Latch-up immunity | Designed-in immunity per JEDEC JESD78 - prevents catastrophic failure during input overvoltage events in harsh environments. |
Applications
| Smoke and Heat Detector | Pressure Transmitter |
|---|---|
Use Scenario: Amplifies low-level output from ionization or thermistor-based fire detection elements in battery-powered alarm units. IC Role / Device Role / Timing Role: Dual-channel signal conditioner: one amp buffers reference voltage, the other amplifies sensor delta-V with gain ≥100. Use Value: 27 µA supply current extends 9 V alkaline battery life beyond 5 years; rail-to-rail output ensures full ADC utilization at 3 V supply. |
Use Scenario: Conditioner for piezoresistive pressure sensor bridges in industrial process control loops. IC Role / Device Role / Timing Role: Instrumentation amplifier front-end: configured as difference amplifier with matched external resistors. Use Value: 0.6 pA input bias current prevents bridge imbalance errors; ground-sensing input enables direct 0–50 mV bridge readout without level-shifting. |
| Temperature Transmitter | Motion Detector |
Use Scenario: Signal conditioning for RTD or thermistor circuits in 4–20 mA loop-powered field devices. IC Role / Device Role / Timing Role: Precision voltage-to-current converter driver: one amp sets reference, the other drives current source transistor. Use Value: 9 mV max VIO limits temperature measurement error to <0.5°C over 0–100°C range; 85°C operating limit matches industrial ambient specs. |
Use Scenario: Amplifier for PIR sensor outputs in low-power occupancy sensors with wake-on-motion capability. IC Role / Device Role / Timing Role: AC-coupled gain stage: first amp filters and amplifies microvolt-level PIR signal; second amp drives comparator threshold. Use Value: Sub-1 pA input bias avoids leakage-induced false triggers; 3 V operation aligns with coin-cell or energy-harvesting power sources. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual low-power op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2372IDR | Lower VIO (3 mV max), higher supply current (55 µA max), same TSSOP-8 package. | Better precision but 2× higher power draw - unsuitable for multi-year battery life targets. | Select TLV2372IDR only when offset voltage dominates system error budget and power is secondary. |
| LPV322MG/NOPB | Higher VIO (2.5 mV typ), wider supply range (2.7–5.5 V), same 27 µA max IDD, SC70-8 package. | Smaller footprint but lower ESD rating (1500 V HBM) and no guaranteed latch-up immunity. | Choose LPV322MG/NOPB only when board space is constrained and environmental robustness is less critical than size. |
Compared with TLV2322PWLE, TLV2372IDR trades 2× supply current for 3× lower offset voltage, while LPV322MG/NOPB offers identical power but reduced package reliability and no latch-up guarantee - making TLV2322PWLE the optimal balance for rugged, long-life industrial sensor nodes.

FAQ
What is the maximum operating temperature range for the TLV2322PWLE?
The TLV2322PWLE is fully specified and tested over an operating free-air temperature range of –40°C to +85°C. All key parameters-including supply current (27 µA max), input offset voltage (9 mV max), and common-mode input range-are guaranteed across this full industrial temperature span without derating.
Does the TLV2322PWLE support true rail-to-rail input operation?
The TLV2322PWLE does not support rail-to-rail input: its common-mode input voltage range extends to the negative rail (GND) and up to VDD – 1 V at 25°C (VDD – 1.2 V over full temperature range). The inputs cannot safely accept signals at the positive rail, but full ground-referenced operation is supported.
Can the TLV2322PWLE drive a 10 kΩ load while maintaining rail-to-rail output swing?
Yes - the TLV2322PWLE guarantees rail-to-rail output swing into loads ≥10 kΩ. At 1 mA load (equivalent to 10 kΩ at 10 V, but relevant for 3 V systems), VOL is ≤150 mV and VOH is ≥VDD – 1.2 V. For heavier loads, output swing degrades predictably per the datasheet curves.
Is the TLV2322PWLE pin-compatible with other dual op-amps in TSSOP-8 packages?
No - the TLV2322PWLE has a non-standard pinout (e.g., VDD+ on pin 8, GND on pin 4) that differs from industry-standard dual op-amps like LMV358 or MCP6022. PCB layout must follow the exact TLV2322PWLE pin mapping shown in Figure 4-2 of the datasheet.
What is the typical input bias current of the TLV2322PWLE at 85°C?
The typical input bias current of the TLV2322PWLE at 85°C is 175 pA, with a maximum of 2000 pA. This remains exceptionally low compared to bipolar-input op-amps and ensures minimal loading error when interfacing with high-impedance sensors such as pH electrodes or photodiodes.
