Product details
Overview
TLV2322IPWR from Texas Instruments is a dual, low-voltage, rail-to-rail output operational amplifier optimized for single-supply battery-powered systems. It operates from 2.7V to 8V, draws only 27µA per channel over –40°C to +85°C, and features rail-to-rail output swing with input common-mode range extending to the negative rail and up to VDD –1V. It is widely used in sensor signal conditioning for field transmitters.
For engineers reviewing the TLV2322IPWR datasheet, TLV2322IPWR pinout, TLV2322IPWR application, or TLV2322IPWR equivalent, this page delivers verified electrical specs, package-confirmed pin functions, real-world use cases in low-power industrial sensing, and two validated alternative op-amps with documented functional trade-offs.
Technical Context
The TLV2322IPWR uses Texas Instruments' LinCMOS™ silicon-gate process to achieve ultra-low supply current (27µA/channel) while maintaining 10¹²Ω input impedance and sub-picoampere bias currents. Its input stage supports single-supply operation with common-mode voltage down to ground and up to VDD –1V at 25°C.
Output stage design enables rail-to-rail swing - low-level output voltage as low as 115mV above ground at 1mA load - and ensures latch-up immunity with ±100mA terminal fault tolerance. ESD protection meets MIL-STD-883C, Method 3015.2 (2000V HBM).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7V to 8V - supports direct connection to 3V and 5V logic rails and Li-ion battery discharge profiles. |
| Quiescent Current per Channel | 27µA max over –40°C to +85°C - enables multi-year operation in coin-cell–powered sensor nodes. |
| Input Offset Voltage | 9mV max at 25°C - sufficient for precision DC-coupled amplification in pressure/temperature transmitter front-ends. |
| Unity-Gain Bandwidth | 27kHz at 3V, 85kHz at 5V - suitable for low-frequency sensor signals (e.g., thermocouple, RTD, strain gauge) without instability. |
| Common-Mode Input Range | Extends to negative rail and up to VDD –1V at 25°C - allows direct interfacing with grounded sensors and single-supply reference circuits. |
| Output Voltage Swing | Rail-to-rail - low-level output as low as 115mV above GND at 1mA load, enabling full dynamic range utilization in 3V systems. |
| Input Bias Current | 0.6pA typical at 25°C - preserves signal integrity when amplifying high-impedance sources like piezoresistive or capacitive sensors. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual low-voltage op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2372IDR | Lower input offset (3mV typ), higher supply current (55µA/channel), same PW package. | Better DC accuracy but reduces battery life in ultra-low-power designs. | Choose TLV2372IDR when offset-critical sensor calibration dominates over current budget. |
| LPV521MG/NOPB | Even lower supply current (320nA/channel), but slower (10kHz GBW), single-channel, SC70-5 package. | Not pin-compatible; requires PCB redesign and additional device count for dual functionality. | Choose LPV521MG/NOPB only for new designs where nanoamp current is mandatory and bandwidth ≤10kHz suffices. |
Compared with TLV2322IPWR, TLV2372IDR trades 28× higher supply current for 3× lower offset, while LPV521MG/NOPB achieves 84× lower current at the cost of halved bandwidth and loss of dual-channel integration - making TLV2322IPWR the optimal balance for general-purpose low-power industrial sensing.

FAQ
What is the maximum operating temperature range for the TLV2322IPWR?
The TLV2322IPWR is fully specified and tested over an operating free-air temperature range of –40°C to +85°C. All key parameters - including supply current (27µA max/channel), input offset voltage (9mV max), and common-mode input range - are guaranteed across this full industrial temperature range, making it suitable for deployment in outdoor and factory-floor environments.
Does the TLV2322IPWR support true rail-to-rail input operation?
The TLV2322IPWR does not support rail-to-rail input: its common-mode input voltage range extends to the negative rail (GND) and up to VDD –1V at 25°C (or VDD –1.2V over full temperature range). However, its output is rail-to-rail - swinging within 115mV of GND and 200mV of VDD at 1mA load - which is confirmed in Section 5.4 of the official datasheet.
What package type is used for the TLV2322IPWR part number?
The TLV2322IPWR uses the PW package: an 8-pin thin-shrink small-outline package (TSSOP) measuring 2.95mm × 2.8mm with a maximum height of 1.1mm. This surface-mount, lead-free, RoHS-compliant package is optimized for space-constrained portable and field-deployable equipment.
Can the TLV2322IPWR operate from a 2.7V supply?
Yes - the TLV2322IPWR is fully functional and characterized at 2.7V, the minimum recommended supply voltage. It maintains specified performance including 27µA max supply current per channel, 9mV max input offset, and rail-to-rail output swing down to 2.7V, enabling compatibility with partially discharged lithium coin cells and low-dropout regulator outputs.
Is the TLV2322IPWR pin-compatible with other members of the TLV232x family?
The TLV2322IPWR (dual-channel, 8-pin) shares identical pinout with other TLV2322 variants (e.g., TLV2322IDR, TLV2322CPW) in the PW package, but is not pin-compatible with the quad-channel TLV2324 (14-pin). Pin functions - including VDD+, VDD–/GND, OUT1/OUT2, and paired inputs - are fixed per the SOIC/TSSOP 8-pin layout shown in Figure 4-2 of the datasheet.
