Product details
Overview
TLV2332IDR from Texas Instruments is a dual-channel, low-voltage, medium-power operational amplifier in the LinCMOS™ family, designed for single-supply operation from 2 V to 8 V over –40°C to 85°C. It delivers 300 kHz unity-gain bandwidth and 0.38 V/µs slew rate at 3 V, with rail-to-rail output swing down to the negative rail and common-mode input range extending below ground - ideal for battery-powered sensor signal conditioning and portable instrumentation.
For engineers reviewing the TLV2332IDR datasheet, TLV2332IDR pinout, TLV2332IDR application, or TLV2332IDR equivalent, key selection criteria include its 310 µA max supply current per amplifier, 10¹² Ω typical input impedance, ±30 mA output drive capability, ESD protection up to 2000 V (MIL-STD-883C), and compatibility with low-noise, high-impedance source interfacing such as piezoelectric sensors and precision filter stages.
Technical Context
The TLV2332IDR uses silicon-gate LinCMOS™ process technology to achieve ultra-low input bias current (0.6 pA typ at 25°C) and high input impedance, enabling direct coupling to high-impedance transducers without significant loading error. Its internal architecture supports stable operation with capacitive loads up to 20 pF and features built-in latch-up immunity and robust ESD protection circuitry.
It operates fully functional at minimum 2-V supply and is fully characterized at both 3 V and 5 V, with common-mode input voltage range specified from –0.2 V to VDD–1 V at 25°C - allowing true single-supply operation in systems where input signals may dip below ground reference.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2 V to 8 V - enables direct integration into 3.3 V and 5 V systems, plus compatibility with emerging 2.5 V and 2.7 V rails. |
| Unity-Gain Bandwidth | 300 kHz at 3 V - sufficient for anti-aliasing filters, sensor amplification, and audio preamp stages in portable devices. |
| Slew Rate | 0.38 V/µs at 3 V - supports moderate-speed signal conditioning without distortion in DC-coupled measurement paths. |
| Input Bias Current | 0.6 pA typ at 25°C - minimizes voltage error across high-value feedback or sensor resistors (>1 MΩ). |
| Common-Mode Input Range | Extends to –0.2 V (below GND) and up to VDD–1 V - allows input signals to operate across full single-supply range including sub-ground transducer outputs. |
| Output Voltage Swing | Includes negative rail (rail-to-rail output) - maximizes dynamic range when driving ADC inputs or low-voltage logic interfaces. |
| ESD Protection | 2000 V HBM (MIL-STD-883C, Method 3015.2) - reduces handling sensitivity and improves field reliability in unshielded environments. |
Pinout & Package
TLV2332IDR is housed in an 8-pin SOIC (Small Outline Integrated Circuit) package, designated "D" per TI's packaging nomenclature, tape-and-reel format indicated by the "R" suffix. The device measures 4.9 mm × 3.9 mm × 1.75 mm (max height) and is RoHS-compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OUT1) | Amplifier 1 output | Delivers amplified differential signal; capable of sourcing/sinking ±30 mA; swings rail-to-rail under load. |
| 2 (IN–1) | Inverting input, Amp 1 | High-impedance node (10¹² Ω); accepts feedback network or inverted signal path; sensitive to layout-induced noise. |
| 3 (IN+1) | Non-inverting input, Amp 1 | High-impedance node; used for reference or direct sensor connection; supports common-mode voltages down to –0.2 V. |
| 4 (GND / VDD–) | Negative supply / ground | Return path for both amplifiers; serves as reference for single-supply operation; must be low-impedance for stability. |
| 5 (VDD) | Positive supply | Accepts 2 V–8 V; decoupling capacitor (0.1 µF ceramic) required within 1 cm for high-frequency PSRR performance. |
| 6 (IN+2) | Non-inverting input, Amp 2 | Independent high-Z input; identical specs to Pin 3; enables dual-channel signal processing without cross-talk. |
| 7 (IN–2) | Inverting input, Amp 2 | Independent high-Z input; matches Pin 2 electrical behavior; supports separate feedback networks per channel. |
| 8 (OUT2) | Amplifier 2 output | Functionally identical to Pin 1; allows simultaneous dual-signal amplification (e.g., differential pair or I/V + buffer). |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail output swing | Enables maximum signal utilization in low-voltage systems (e.g., 3.3 V ADC reference), reducing need for level-shifting circuitry. |
| Input common-mode range includes negative rail | Permits direct interface with sub-ground sensor outputs (e.g., thermocouples, bridge transducers) without external biasing. |
| Ultra-low input bias current (0.6 pA typ) | Preserves accuracy in high-impedance gain networks (e.g., >10 MΩ feedback) and prevents drift in integrator or filter applications. |
| Low quiescent current (620 µA max per amp) | Supports multi-year battery life in always-on IoT endpoints and portable medical monitors operating from coin cells or Li-ion. |
| LinCMOS™ process technology | Provides inherent latch-up immunity and stable parametric performance across temperature, critical for industrial control loop amplifiers. |

| Battery-Powered Medical Monitoring | Low-Power Analog Front-End for Wearables |
Use Scenario: Amplifying ECG electrode signals in a disposable patch monitor running 72 hours on a CR2032 coin cell. IC Role / Device Role / Timing Role: Dual-channel configuration for lead-I/lead-II differential acquisition with integrated right-leg drive (RLD) buffer.

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 |
|---|---|---|---|
| TLV2432CDR | Higher supply current (1.2 mA/amp), wider VDD range (2.7–16 V), lower input offset (2 mV max), no sub-ground input capability. | Not suitable for <2.7 V systems or sub-ground sensor interfacing; better for higher-precision, higher-power industrial analog modules. | Select TLV2432CDR only if system requires >5 V supply or tighter offset spec; avoid for battery-powered sub-3 V designs. |
| MCP6022-E/SN | Lower quiescent current (180 µA/amp), rail-to-rail I/O, but limited common-mode range (VSS to VDD–0.3 V), no sub-ground input. | Cannot accept inputs below ground; unsuitable for thermocouple or bridge-based sensors requiring negative common-mode headroom. | Prefer MCP6022-E/SN for ultra-low-power, ground-referenced sensor nodes; reject for any application needing true sub-ground input operation. |
Compared with TLV2332IDR, TLV2432CDR trades sub-ground input capability and ultra-low bias current for higher precision and wider supply range, while MCP6022-E/SN offers lower power but sacrifices essential negative-rail input support - making TLV2332IDR uniquely suited for true single-supply, wide common-mode, battery-constrained designs.

FAQ
What is the maximum supply voltage rating for TLV2332IDR?
The absolute maximum supply voltage for TLV2332IDR is 8 V, as specified in the Absolute Maximum Ratings table. Operation above this voltage risks permanent damage. For reliable long-term use, TI recommends staying within the recommended operating range of 2 V to 8 V, with full characterization at 3 V and 5 V.
Does TLV2332IDR support true rail-to-rail input operation?
No - TLV2332IDR supports rail-to-rail *output* swing and a common-mode input range that extends *below* the negative rail (to –0.2 V at 25°C) and up to VDD–1 V, but does not reach the positive rail. This "beyond-the-rail" input capability is critical for single-supply sensor interfaces, but it is not full rail-to-rail input.
Can TLV2332IDR drive capacitive loads reliably?
Yes - TLV2332IDR is characterized for stable operation with capacitive loads up to 20 pF, as confirmed in Figures 25–32 of the SLOS189 datasheet. For loads exceeding 20 pF, external isolation resistance (e.g., 10–50 Ω in series with the output) is recommended to maintain phase margin above 36°.
What is the input offset voltage specification for TLV2332IDR at 85°C?
At full temperature range (–40°C to 85°C), the input offset voltage for TLV2332IDR is guaranteed to be ≤11 mV, per the "TLV2332I electrical characteristics" table. At 25°C and 3 V supply, the typical value is 0.6 mV with a maximum of 9 mV.
Is TLV2332IDR pin-compatible with other devices in the TLV233x family?
Yes - TLV2332IDR shares identical 8-pin SOIC (D) pinout with TLV2332ID, TLV2332IP, and TLV2332IPWLE. All TLV2332 variants use the same pin assignment: OUT1, IN–1, IN+1, GND, VDD, IN+2, IN–2, OUT2 - enabling drop-in replacement across package types where board layout permits.
