Product details
Overview
TLV2322ID from Texas Instruments is a dual, low-voltage, rail-to-rail output operational amplifier optimized for single-supply operation in battery-powered systems. It delivers 27 µA max supply current per channel at –40°C to +85°C, 9 mV max input offset voltage, and operates from 2.7 V to 8 V. 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 TLV2322ID datasheet, TLV2322ID pinout, TLV2322ID application, or TLV2322ID equivalent, this page provides verified electrical specifications, SOIC-8 package details, real-world use scenarios, and two validated alternative op-amps for low-voltage sensor signal conditioning.
Technical Context
The TLV2322ID 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, enabling true single-supply interfacing with grounded sensors.
It features rail-to-rail output swing, 27 kHz unity-gain bandwidth at 3 V, and 85 kHz at 5 V. The device incorporates internal ESD protection rated to 2000 V (MIL-STD-883C, Method 3015.2) and is latch-up immune - critical for field-transmitter reliability in industrial environments.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar low-voltage, low-power operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2422IDR | Higher supply current (125 µA/ch), wider VIO range (2.5 mV max), same SOIC-8 package. | Better DC precision but 4.6× higher power draw - unsuitable for multi-year battery operation. | Select TLV2422IDR only when offset voltage <2.5 mV is mandatory and power budget allows ≥100 µA/ch. |
| LPV821DRX | Lower supply current (650 nA/ch), smaller TSSOP-8 package, but reduced bandwidth (1.9 kHz) and VIO (1.25 mV max). | Optimized for ultra-low-power IoT endpoints; insufficient bandwidth for fast transient detection in motion sensors. | Choose LPV821DRX for sub-µA always-on wake-up circuits; avoid for transmitter signal chains requiring >10 kHz bandwidth. |
Compared with TLV2322ID, TLV2422IDR trades power efficiency for improved DC accuracy, while LPV821DRX achieves nanoamp operation at the cost of bandwidth and drive strength - TLV2322ID uniquely balances 27 µA/ch consumption, 27 kHz bandwidth, and SOIC-8 manufacturability for industrial sensor front-ends.

FAQ
What is the maximum operating temperature range for the TLV2322ID?
The TLV2322ID 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 range, making TLV2322ID suitable for outdoor and factory-floor deployments.
Does the TLV2322ID support rail-to-rail input operation?
No, the TLV2322ID 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). This means the inputs cannot accept signals at the positive supply rail, but they do fully accommodate grounded sensor references - a key enabler for single-supply designs.
Can the TLV2322ID drive capacitive loads directly?
The TLV2322ID is not unity-gain stable into heavy capacitive loads. Driving >100 pF directly may cause peaking or oscillation. For loads exceeding 100 pF (e.g., long PCB traces or ADC input capacitance), TI recommends adding a series resistor (10–100 Ω) between the TLV2322ID output and the load to isolate capacitance and maintain phase margin - confirmed in Figure 6-1 and Section 6.1 of the datasheet.
Is the TLV2322ID pin-compatible with other dual op-amps in SOIC-8?
The TLV2322ID follows the industry-standard dual op-amp pinout (Pin 1 = OUT1, Pin 2 = 1IN–, Pin 3 = 1IN+, Pin 4 = GND, Pin 5 = 2IN+, Pin 6 = 2IN–, Pin 7 = OUT2, Pin 8 = VDD+), matching devices such as LM358, TL072, and MCP602. However, electrical behavior (e.g., input stage, supply current, bandwidth) differs significantly - direct replacement requires validation of bias network and stability margins.
What is the typical input noise voltage of the TLV2322ID at 1 kHz?
The TLV2322ID has a typical equivalent input noise voltage of 68 nV/√Hz at 1 kHz, as measured with RS = 20 Ω and specified in Sections 5.5 and 5.6 of the datasheet. This noise level supports accurate digitization of low-level sensor signals (e.g., thermopiles, strain gauges) when paired with 12-bit or 14-bit ADCs in low-frequency (<10 kHz) measurement applications.
