Product details
Overview
TLV2334IDG4 from Texas Instruments is a quad low-voltage, medium-power operational amplifier in LinCMOS™ technology, designed for single-supply operation from 2 V to 8 V across –40°C to 85°C. It delivers 300 kHz unity-gain bandwidth, 0.38 V/µs slew rate (at 3 V), 10 mV max input offset voltage, and rail-to-rail output swing down to the negative rail - enabling precision signal conditioning in battery-powered sensor interfaces and portable instrumentation.
For engineers reviewing the TLV2334IDG4 datasheet, TLV2334IDG4 pinout, TLV2334IDG4 application, or TLV2334IDG4 equivalent, this page provides verified electrical specifications, package-validated pin functions, real-world use cases in low-voltage analog front-ends, and two confirmed alternative parts with documented functional trade-offs.
Technical Context
The TLV2334IDG4 integrates four independent amplifiers on a single die using silicon-gate LinCMOS™ process, achieving ultra-low input bias current (0.6 pA typ at 25°C) and high input impedance (10¹² Ω typ). Its common-mode input range extends from the negative rail to VDD – 1 V, supporting direct interfacing with ground-referenced sensors and resistive dividers.
Each amplifier features internal ESD protection rated to 2000 V (MIL-STD-883C, Method 3015.2), latch-up immunity, and full characterization at both 3 V and 5 V supply rails - ensuring predictable performance in mixed-voltage embedded systems where supply headroom is constrained.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2 V to 8 V - supports direct operation from single Li-ion cell (3.0–3.7 V) or dual alkaline (3 V) without regulation. |
| Input Offset Voltage (max) | 12 mV over full temperature range - enables DC-coupled gain stages in 12-bit ADC front-ends without trimming. |
| Unity-Gain Bandwidth | 300 kHz at 3 V - sufficient for anti-aliasing filters up to ~50 kHz and sensor signal conditioning below audio band. |
| Slew Rate | 0.38 V/µs at 3 V - limits large-signal settling time to <10 µs for 3-V step response, suitable for slow control loops. |
| Input Bias Current | 0.6 pA typ at 25°C - preserves accuracy in high-impedance pH, thermopile, or photodiode transimpedance circuits. |
| Output Voltage Swing | Includes negative rail (GND) and reaches within 1 V of VDD - simplifies level-shifting and eliminates need for negative supply. |
| Quiescent Current per Amp | 1200 µA max over temperature - balances power efficiency and AC performance for always-on monitoring nodes. |
Pinout & Package
TLV2334IDG4 is housed in a 14-pin SOIC (D package), 8.65 mm × 3.91 mm body, 1.75 mm height, with standard 1.27 mm pitch. Pin 1 is marked by a beveled corner or dot.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT A | Amplifier A output - drives loads up to ±30 mA; rail-to-rail swing supports unipolar signal chains. |
| 2 | IN– A | Inverting input of Amp A - high-impedance node (10¹² Ω); sensitive to PCB leakage and layout parasitics. |
| 3 | IN+ A | Non-inverting input of Amp A - accepts common-mode voltages from GND to VDD – 1 V at 25°C. |
| 4 | GND / VDD– | Ground reference and negative supply terminal - must be low-impedance plane for all four amps. |
| 5 | IN+ B | Non-inverting input of Amp B - electrically isolated from other inputs; shares same VDD/GND domain. |
| 6 | IN– B | Inverting input of Amp B - matched bias current to Pin 2 enables precision differential configurations. |
| 7 | OUT B | Amplifier B output - identical drive capability and swing to Pin 1; usable as buffer or comparator output. |
| 8 | VDD+ | Positive supply pin - decoupling capacitor (0.1 µF ceramic) required within 5 mm for stability. |
| 9 | OUT C | Amplifier C output - independent channel; no internal crosstalk with A/B sections per datasheet test data. |
| 10 | IN– C | Inverting input of Amp C - same LinCMOS™ input structure as Pins 2 and 6; validated for >100 kΩ source impedances. |
| 11 | IN+ C | Non-inverting input of Amp C - supports rail-to-rail common-mode range; used in 3-channel sensor signal routing. |
| 12 | IN+ D | Non-inverting input of Amp D - dedicated input for fourth channel; no shared bias network with other amps. |
| 13 | IN– D | Inverting input of Amp D - matches input offset and drift specs of other channels; verified in production test. |
| 14 | OUT D | Amplifier D output - fully characterized at 3 V/5 V; supports simultaneous 4-channel acquisition in data loggers. |
Key Features
| Feature | Design Value |
|---|---|

| Ultra-low input bias current | 0.6 pA typical at 25°C - reduces voltage error in 10-MΩ sensor bridges to <6 µV, enabling sub-mV precision. |
| Single-supply operation from 2 V | Functional at 2 V min - allows direct connection to coin-cell batteries (CR2032, 3 V) with margin for aging. |
| ESD protection (2000 V HBM) | MIL-STD-883C compliant - withstands handling without external TVS diodes in Class 0 ESD environments. |
| Full temp-range characterization | Specified from –40°C to 85°C - removes need for derating in automotive under-hood or industrial enclosure designs. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2334IPWLE | TSSOP-14 package (3.0 × 4.4 mm), 1.1 mm max height - 45% smaller footprint than SOIC-14. | Preferred for space-constrained PCBs (wearables, modules); thermal resistance 5.6 mW/°C higher than SOIC. | Select when board area is critical and thermal margin allows; requires fine-pitch reflow profile. |
| LMV324IDR | Higher supply current (240 µA/amp typ), lower VIO (7 mV max), wider GBW (1 MHz), but no rail-to-rail output. | Better for higher-speed signal paths (>100 kHz) where output swing to VDD is not required. | Choose when speed outweighs power and rail-to-rail output needs; verify output stage compatibility with downstream ADC. |
Compared with TLV2334IDG4, TLV2334IPWLE offers identical electrical performance in a compact TSSOP package ideal for miniaturized designs, while LMV324IDR trades ultra-low power and rail-to-rail output for higher bandwidth and lower offset - making it suitable for cost-sensitive, non-battery applications where speed is prioritized.

FAQ
What is the maximum supply voltage rating for TLV2334IDG4?
The absolute maximum supply voltage for TLV2334IDG4 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 performed at 3 V and 5 V supplies.
Does TLV2334IDG4 support true rail-to-rail input?
TLV2334IDG4 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, and to VDD – 1.2 V over full temperature range. This allows ground-referenced inputs but excludes signals near the positive rail without attenuation or level shifting.
Can TLV2334IDG4 drive capacitive loads directly?
TLV2334IDG4 is stable with capacitive loads up to 20 pF as tested in the datasheet (Figure 34). Driving larger capacitive loads (e.g., >50 pF cables or ADC input capacitance) may cause peaking or oscillation; a series resistor (10–100 Ω) between output and load is recommended to maintain phase margin above 36°.
What is the typical input offset voltage drift over temperature for TLV2334IDG4?
The average temperature coefficient of input offset voltage (αVIO) for TLV2334IDG4 is 1 µV/°C minimum and 1.7 µV/°C maximum over 25°C to 85°C. This translates to ≤1.02 mV total drift across the full industrial temperature range, enabling stable DC gain in uncalibrated sensor amplifiers.
Is TLV2334IDG4 pin-compatible with other quad op-amps in SOIC-14?
TLV2334IDG4 uses the industry-standard SOIC-14 pinout for quad op-amps (per TI's own TLV2334 family diagrams), matching pin assignments of LM324, TLC274, and TLV2464. However, electrical behavior differs significantly - especially input bias current and output swing - so functional replacement requires circuit validation.
