Product details
Overview
TLV2332IDRG4 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 across –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 TLV2332IDRG4 datasheet, TLV2332IDRG4 pinout, TLV2332IDRG4 application, or TLV2332IDRG4 equivalent, key selection criteria include its 10¹² Ω input impedance, 310 µA max supply current per amplifier over temperature, ±1 mA output drive capability, and guaranteed performance at 3 V and 5 V - critical for low-power analog front-ends in medical wearables and IoT edge nodes.
Technical Context
The TLV2332IDRG4 implements a silicon-gate LinCMOS™ process enabling ultra-low input bias current (0.6 pA typ at 25°C) and high DC precision, with internal ESD protection rated to 2000 V (MIL-STD-883C, Method 3015.2). Its architecture supports stable operation with capacitive loads up to 20 pF and maintains ≥39° phase margin at unity gain.
It features fully differential input stage design allowing common-mode voltage operation from –0.2 V to VDD–1 V at 25°C, and rail-inclusive output stage delivering VOL ≤ 150 mV at 1 mA load - enabling direct interfacing with ADCs and microcontrollers operating on shared 3-V rails.

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2372IDR | Lower supply current (20 µA typ per amp), lower bandwidth (1.5 MHz), higher VIO (3 mV max), same SOIC-8 package. | Better suited for ultra-low-power sleep-mode wake-up amplification; less suitable for 300-kHz signal paths. | Select TLV2372IDR only when supply current is primary constraint and bandwidth >200 kHz is unnecessary. |
| LMV358IDR | Higher supply current (150 µA typ per amp), wider supply range (2.7–5.5 V), rail-to-rail output only, no rail-to-rail input. | Requires ≥2.7 V supply; cannot accept inputs below GND - unsuitable for ground-referenced sensor buffers. | Choose LMV358IDR only if operating strictly at 3.3 V and input common-mode never goes below GND. |
Compared with TLV2332IDRG4, TLV2372IDR trades bandwidth and input voltage range for microamp-level quiescent current, while LMV358IDR sacrifices input rail-to-rail capability and low-voltage operation for higher speed and cost efficiency at 3.3 V - making TLV2332IDRG4 uniquely balanced for 2–5 V, precision, single-supply sensor interfaces.

FAQ
What is the minimum supply voltage for reliable operation of the TLV2332IDRG4?
The TLV2332IDRG4 is fully functional down to 2 V supply voltage across its specified operating temperature range (–40°C to 85°C), and is fully characterized and tested at both 3 V and 5 V. At 2 V, key parameters including bandwidth, slew rate, and output swing remain within guaranteed limits per the datasheet's recommended operating conditions - making TLV2332IDRG4 suitable for single-cell lithium or two-cell alkaline battery systems where voltage sags below 3 V.
Does the TLV2332IDRG4 support rail-to-rail input and output operation?
The TLV2332IDRG4 supports rail-to-rail output swing (including the negative rail) and a common-mode input voltage range that extends 0.2 V below the negative rail (GND) and up to VDD–1 V at 25°C. While not fully rail-to-rail on the input high side, its extended common-mode range enables true single-supply operation for most sensor interfaces. This behavior is explicitly confirmed in the "Recommended Operating Conditions" table and "Electrical Characteristics" section of the TLV2332IDRG4 datasheet.
What is the maximum output current capability of the TLV2332IDRG4?
The TLV2332IDRG4 is rated for ±30 mA absolute maximum output current per amplifier, but its specified linear output drive is ±1 mA into resistive loads while maintaining VOH ≥ 1.7 V and VOL ≤ 150 mV at 3 V supply. Sustained operation above ±1 mA may cause thermal derating or reduced precision; for higher-current applications, external buffers should be used. This specification is verified in the "Electrical Characteristics" table under VOH/VOL test conditions.
How does the TLV2332IDRG4 handle capacitive loads?
The TLV2332IDRG4 is characterized for stability with capacitive loads up to 20 pF, as confirmed in Figures 21 and 22 (frequency response with CL = 20 pF) and the "Operating Characteristics" tables. Driving larger capacitive loads (e.g., >50 pF) may induce peaking or oscillation; for such cases, an isolation resistor (10–100 Ω) between the TLV2332IDRG4 output and the load capacitance is recommended to preserve phase margin ≥39°.
Is the TLV2332IDRG4 pin-compatible with other dual op-amps in SOIC-8 package?
The TLV2332IDRG4 uses the industry-standard dual op-amp SOIC-8 pinout (pin 1 = OUT1, pin 2 = IN–1, pin 3 = IN+1, pin 4 = GND, pin 5 = IN+2, pin 6 = IN–2, pin 7 = OUT2, pin 8 = VDD), matching TI's TLV2372, LMV358, and many generic dual op-amps. However, functional compatibility requires verification of supply range, input/output voltage ranges, and quiescent current - e.g., LMV358 lacks rail-to-rail input, and TLV2372 has different bandwidth and offset specs. TLV2332IDRG4 is not a drop-in replacement without circuit review.
