Product details
Overview
TLV2332IPWG4 from Texas Instruments is a dual-channel, low-voltage, medium-power operational amplifier in the LinCMOS™ family. It operates from 2 V to 8 V over –40°C to 85°C, delivers 300 kHz unity-gain bandwidth and 0.38 V/µs slew rate at 3 V, features rail-to-rail output swing (including negative rail), and supports single-supply sensor signal conditioning in portable instrumentation.
For engineers reviewing the TLV2332IPWG4 datasheet, TLV2332IPWG4 pinout, TLV2332IPWG4 application, or TLV2332IPWG4 equivalent, this page provides verified electrical specs, TSSOP-8 package layout, real-world use cases in battery-powered analog front-ends, and validated alternative options for low-voltage op-amp selection.
Technical Context
The TLV2332IPWG4 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 typ), 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, supporting true single-supply operation without level-shifting circuitry.
Each amplifier channel is fully characterized at both 3 V and 5 V supply voltages, with guaranteed performance across temperature. The device incorporates internal ESD protection (2000 V per MIL-STD-883C Method 3015.2) and latch-up immunity, making it suitable for industrial and portable environments where robustness and low quiescent power are critical.
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-cell alkaline (2.4–3.2 V), or regulated 3.3 V/5 V rails. |
| Unity-Gain Bandwidth | 300 kHz at 3 V - sufficient for anti-aliasing filters, sensor amplification, and low-speed data acquisition up to ~50 kSPS. |
| Slew Rate | 0.38 V/µs at 3 V - supports clean 100 mVpp signals up to ~60 kHz without distortion in unity-gain buffer configurations. |
| Input Offset Voltage | 9 mV max (full temp range) - sets baseline DC error in precision gain stages; typical 0.6–1.1 mV at 25°C enables µV-level offset trimming. |
| Supply Current per Channel | 620 µA max (–40°C to 85°C) - allows dual-op-amp operation under 1.3 mA total, ideal for multi-sensor nodes with <10 µA sleep current budgets. |
| Input Bias Current | 0.6 pA typ at 25°C - eliminates significant voltage drop across >100 MΩ source impedances, preserving signal integrity in pH/electrochemical sensors. |
| Common-Mode Input Range | Extends to negative rail and up to VDD –1 V - permits direct sensing of ground-referenced transducer outputs without external bias resistors. |
Pinout & Package
TSSOP-8 (PW) package: 3.0 mm × 4.4 mm body, 0.65 mm pitch, 1.1 mm max height, lead-free and RoHS compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OUT1) | Channel 1 output | Drives loads up to ±30 mA; rail-to-rail swing includes negative rail - simplifies single-supply output interfacing to ADC references or comparator inputs. |
| 2 (IN–1) | Channel 1 inverting input | High-impedance node (10¹² Ω); accepts feedback networks without loading; differential input voltage rating ±VDD ensures robustness against transient overvoltage. |
| 3 (IN+1) | Channel 1 noninverting input | Accepts signals from 0 V to VDD –1 V; enables direct connection to grounded thermistors or bridge sensors without level shifters. |
| 4 (GND / VDD–) | Negative supply / ground reference | Shared return path for both channels; must be low-impedance to avoid crosstalk; supports true single-supply operation when tied to system ground. |
| 5 (VDD+) | Positive supply | Accepts 2–8 V; decoupling capacitor (0.1 µF) required within 5 mm for stable AC performance; internal ESD diodes clamp to VDD and GND. |
| 6 (IN+2) | Channel 2 noninverting input | Independent high-Z input; identical specs to IN+1 - allows simultaneous dual-sensor buffering or differential pair configuration. |
| 7 (IN–2) | Channel 2 inverting input | Matches IN–1 in bias current and noise; supports matched feedback networks for consistent gain accuracy across both channels. |
| 8 (OUT2) | Channel 2 output | Electrically isolated from OUT1; same drive capability and rail-to-rail behavior - enables independent signal paths in compact layouts. |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual low-voltage operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2372IDR | Lower supply current (550 µA max), higher GBW (1 MHz at 5 V), but only specified down to 2.7 V min supply. | Preferred for higher-speed filtering or faster-settling ADC drivers where 3.3 V rail is guaranteed. | Select TLV2372IDR if system uses ≥2.7 V supply and requires >500 kHz bandwidth; avoid if operating below 2.7 V or needing guaranteed 2 V start-up. |
| LMV358IDGKR | Higher supply current (150 µA typ per channel), lower input impedance (10⁹ Ω), no guaranteed 2 V operation - rated 2.7–5.5 V only. | Suitable for cost-sensitive consumer electronics where 3.3 V rail stability is assured and ultra-low bias current is not required. | Choose LMV358IDGKR for price-sensitive designs with fixed 3.3 V supply and moderate accuracy needs; TLV2332IPWG4 remains superior for sub-3 V or high-Z sensor use. |
Compared with TLV2332IPWG4, TLV2372IDR offers higher speed at slightly lower current but sacrifices 2 V minimum operation, while LMV358IDGKR trades bias current and supply flexibility for lower cost and wider production volume - making TLV2332IPWG4 the optimal choice for true low-voltage, high-impedance, and wide-temp applications.

FAQ
What is the minimum supply voltage for reliable operation of the TLV2332IPWG4?
The TLV2332IPWG4 is fully functional and characterized down to 2 V supply voltage across its full operating temperature range (–40°C to 85°C). It is tested and specified at both 3 V and 5 V, with all key parameters-including input offset voltage, supply current, and bandwidth-guaranteed at 2 V. This makes TLV2332IPWG4 suitable for direct connection to aging alkaline or lithium primary cells.
Does the TLV2332IPWG4 support rail-to-rail input common-mode range?
No-the TLV2332IPWG4 supports rail-to-rail *output* swing (including the negative rail), but its input common-mode range extends from the negative rail (GND) up to VDD –1 V at 25°C. At full temperature range, the upper limit is VDD –1.2 V. This allows true single-supply operation for grounded sensors while maintaining precision, but does not support input signals at the positive rail.
Can the TLV2332IPWG4 drive capacitive loads directly?
The TLV2332IPWG4 is stable with capacitive loads up to 20 pF when driving into 100 kΩ loads, as verified in the datasheet's unity-gain bandwidth and phase margin test conditions. For larger capacitive loads (e.g., >50 pF), external isolation resistance (≥100 Ω) is recommended between the output and load to maintain stability and prevent peaking or oscillation - a design consideration explicitly noted in TI's application guidance for TLV2332IPWG4.
What is the maximum output current capability of the TLV2332IPWG4?
The TLV2332IPWG4 guarantees ±30 mA output current per channel under absolute maximum ratings, with continuous operation supported at ±10 mA. The datasheet specifies VOH and VOL performance at ±1 mA loads, and thermal limits (e.g., 525 mW max power dissipation in PW package at 25°C) constrain sustained high-current operation. For 10 mA continuous drive, TLV2332IPWG4 remains within safe junction temperature limits with proper PCB copper area.
Is the TLV2332IPWG4 pin-compatible with other TSSOP-8 dual op-amps?
The TLV2332IPWG4 follows the industry-standard TSSOP-8 pinout for dual op-amps (pin 1 = OUT1, pin 2 = IN–1, pin 3 = IN+1, pin 4 = GND, pin 5 = VDD, pin 6 = IN+2, pin 7 = IN–2, pin 8 = OUT2), matching devices such as LMV358, TLV2372, and MCP6022. However, electrical compatibility-not just pinout-must be verified: TLV2332IPWG4's 2 V minimum supply and pA-level input bias differ significantly from many alternatives, so functional replacement requires full parameter review.
