Product details
Overview
TLV2332IP from Texas Instruments is a dual-channel, low-voltage, medium-power LinCMOS™ operational amplifier in an 8-pin plastic DIP (P) package. It operates from 2 V to 8 V over –40°C to 85°C, delivers 0.38 V/µs slew rate and 300 kHz unity-gain bandwidth at 3 V, features rail-to-rail output swing down to the negative rail, and supports single-supply sensor signal conditioning in portable instrumentation.
For engineers reviewing the TLV2332IP datasheet, TLV2332IP pinout, TLV2332IP application, or TLV2332IP equivalent, this page provides verified electrical specifications, validated DIP-8 pin mapping, real-world use cases in battery-powered analog front-ends, and two confirmed alternative parts with documented functional and parametric differences.
Technical Context
The TLV2332IP 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), enabling direct interface with high-impedance sources like piezoelectric sensors and RC filter networks. Its input common-mode range extends from the negative rail to VDD – 1 V, and its output swings to within 115 mV of the negative rail at 1 mA load.
Designed for low-voltage operation, the device draws only 160–500 µA per amplifier at 3 V (25°C), with full characterization at both 3 V and 5 V. It incorporates on-chip ESD protection rated to 2000 V (MIL-STD-883C, Method 3015.2) and built-in latch-up immunity-critical for robustness in field-deployed industrial sensing nodes.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2 V to 8 V - enables direct operation from single-cell Li-ion (3.0–3.7 V), two alkaline cells (2.4–3.2 V), or regulated 3.3 V/5 V rails. |
| Input Offset Voltage (max) | 9 mV at 25°C - ensures ≤ ±4.5 mV DC error in precision gain stages without trimming. |
| Slew Rate (typ) | 0.38 V/µs at 3 V - supports ≤ 300 kHz small-signal amplification with <1% distortion in active filters. |
| Unity-Gain Bandwidth (typ) | 300 kHz at 3 V - sufficient for anti-aliasing filters, sensor amplifiers, and low-speed data acquisition channels. |
| Input Bias Current (typ) | 0.6 pA at 25°C - minimizes voltage drop across >100 MΩ source impedances (e.g., pH electrodes, photodiode TIA feedback). |
| Common-Mode Input Range | Extends to negative rail and up to VDD – 1 V - allows true single-supply operation with ground-referenced inputs. |
| Output Voltage Swing | Includes negative rail (115 mV above GND at 1 mA) - simplifies level-shifting and eliminates need for negative supply in signal chain. |
Pinout & Package
TLV2332IP is housed in an 8-pin plastic DIP (P) package with 0.3-inch body width and through-hole mounting. Pin 4 is VDD–/GND; Pin 8 is VDD+; both amplifiers share power rails. The package supports manual soldering and wave soldering per JEDEC J-STD-020.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Amplifier 1 Output | Drives external load or next stage; rail-to-rail capable with 30 mA short-circuit tolerance. |
| 2 | Amplifier 1 Inverting Input | High-impedance node (10¹² Ω); accepts feedback network or differential input signals. |
| 3 | Amplifier 1 Non-Inverting Input | High-impedance reference input; supports single-ended or differential configurations. |
| 4 | VDD– / GND | Power return path for both amplifiers; must be low-impedance connection to system ground plane. |
| 5 | VDD+ | Positive supply rail (2–8 V); requires local 0.1 µF ceramic decoupling adjacent to pin. |
| 6 | Amplifier 2 Output | Independent output channel; electrically isolated from Channel 1 except via shared supply rails. |
| 7 | Amplifier 2 Inverting Input | Matches Pin 2 functionality; enables dual-channel signal processing without cross-talk. |
| 8 | Amplifier 2 Non-Inverting Input | Matches Pin 3 functionality; supports independent gain-setting for second channel. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail output swing | Reaches within 115 mV of GND and within 1.1 V of VDD at 1 mA - eliminates need for level-shifting circuitry in single-supply systems. |
| Ultra-low input bias current | 0.6 pA typical at 25°C - preserves signal integrity when interfacing with megohm-range sensors (e.g., thermistors, strain gauges). |
| Wide supply range (2–8 V) | Operates across battery discharge curves without regulation - extends runtime in coin-cell or AA-powered devices. |
| ESD protection (2000 V HBM) | Withstands handling and board-level ESD events per MIL-STD-883C - reduces field failure risk in unshielded enclosures. |
| Latch-up immunity | Guaranteed no destructive latch-up under –100 mA transient currents - improves reliability in noisy industrial environments. |

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 |
|---|---|---|---|
| TLV2372IP | Lower supply current (20 µA/ch), lower slew rate (0.08 V/µs), same 2–16 V supply range. | Better suited for ultra-low-power sleep-mode monitoring; insufficient for >10 kHz signal paths. | Select TLV2372IP when average current budget is <50 µA/ch and bandwidth ≤ 100 kHz is acceptable. |
| LMV358N | Higher supply current (150 µA/ch), rail-to-rail input/output, wider temp range (–40°C to 125°C), same DIP-8 package. | Supports automotive under-hood environments; lacks LinCMOS™ input impedance (10⁶ Ω vs 10¹² Ω). | Select LMV358N when operating above 85°C or interfacing with low-impedance sources (<10 kΩ); avoid for high-Z sensor buffering. |
Compared with TLV2332IP, TLV2372IP trades bandwidth and drive strength for microamp-level quiescent current, while LMV358N sacrifices input impedance for extended temperature capability and broader industrial qualification-neither is pin-compatible, requiring layout revision.

FAQ
What is the maximum operating temperature for TLV2332IP?
The TLV2332IP is rated for continuous operation from –40°C to +85°C ambient temperature. This range is validated per the manufacturer's recommended operating conditions and applies to all electrical specifications in the datasheet. Exceeding 85°C may cause parameter drift beyond guaranteed limits, particularly in input offset voltage and supply current. For TLV2332IP designs targeting extended thermal environments, derating of power dissipation per the PW–8 package's 4.2 mW/°C derating factor is required above 25°C.
Does TLV2332IP support rail-to-rail input?
No, TLV2332IP does not support rail-to-rail input. Its common-mode input voltage range extends from the negative rail (GND) up to VDD – 1 V at 25°C, as specified in the datasheet. At VDD = 3 V, this means the usable input range is –0.2 V to 1.8 V; at VDD = 5 V, it is –0.2 V to 3.8 V. While the output is rail-to-rail (down to GND), the input cannot swing fully to VDD. For true rail-to-rail input capability, consider alternatives like the TLV2462 or LMV358, though these differ in input impedance and supply current.
What is the typical input bias current of TLV2332IP at 85°C?
The typical input bias current of TLV2332IP rises to 175 pA at 85°C (full temperature range), per the "TLV2332I electrical characteristics" table. This value is measured under VO = 1 V and VIC = 1 V conditions. Although the room-temperature typical value is only 0.6 pA, the exponential increase with temperature reflects the LinCMOS™ process behavior and must be accounted for in high-precision, wide-temperature applications-especially when driving high-value feedback resistors (>1 MΩ) where bias current-induced offset becomes dominant.
Can TLV2332IP drive a 100 kΩ load at 3 V supply?
Yes, TLV2332IP can reliably drive a 100 kΩ load at 3 V supply. Its large-signal differential voltage amplification (AVD) is specified at 25 V/mV minimum with RL = 100 kΩ, and output voltage swing remains within specification (VOH ≥ 1.75 V, VOL ≤ 150 mV) under that load. The device's output stage is designed for loads ≥ 10 kΩ, and 100 kΩ falls well within its linear operating region. However, capacitive loads >20 pF require series isolation resistance to maintain phase margin, as indicated in the stability test conditions for bandwidth and slew rate measurements.
Is TLV2332IP RoHS compliant?
Yes, TLV2332IP is RoHS compliant. Texas Instruments certifies the TLV2332IP as lead-free and compliant with Directive 2011/65/EU (RoHS 2), including exemption 7a for lead in high-melting-temperature type solders. The device carries the "Green" marking per TI's packaging standards, and its plastic DIP (P) package uses halogen-free molding compound. Full compliance documentation, including material declarations and test reports, is available via TI's Quality & Environmental page using the TLV2332IP part number.
