Product details
Overview
TLV376IDR from Texas Instruments is a single-channel, rail-to-rail input/output precision operational amplifier optimized for low-noise, low-offset, and low-power applications. It delivers 8 nV/√Hz input voltage noise at 1 kHz, 40 μV typical offset voltage, 5.5 MHz gain-bandwidth product, and operates from 2.2 V to 5.5 V supply - making it ideal for ADC buffering in battery-powered medical instrumentation and handheld test equipment.
For engineers reviewing the TLV376IDR datasheet, TLV376IDR pinout, TLV376IDR application, or TLV376IDR equivalent, this page provides verified technical context, real-world design meaning of key specs, validated SOIC-8 package pin functions, application-specific implementation insights, and two confirmed alternative parts with documented functional and parametric differences.
Technical Context
The TLV376IDR uses TI's e-trim™ technology to achieve 40 μV typical input offset voltage and 1.0 μV/°C drift over –40°C to +125°C, enabling high-accuracy dc signal conditioning without external trimming. Its CMOS input stage delivers 0.3 pA typical input bias current and rail-to-rail input common-mode range extending 100 mV beyond both supply rails.
It features unity-gain stability, 2 V/μs slew rate, and drives up to 250 pF capacitive loads directly - critical for driving SAR ADC inputs with minimal settling error. PSRR exceeds 84 dB across 2.2–5.5 V supply, supporting direct battery operation without regulation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain Bandwidth Product | 5.5 MHz - supports stable closed-loop gain ≥10 at 500 kHz for anti-aliasing filter design. |
| Input Voltage Noise Density | 8 nV/√Hz at 1 kHz - enables <1.6 μVPP integrated noise in 0.1–10 Hz band for precision sensor front-ends. |
| Input Offset Voltage (typ) | 40 μV - reduces dc error to <0.1% of full-scale in 16-bit ADC buffer applications with ±2.5 V reference. |
| Quiescent Current | 815 μA per amplifier - allows continuous operation >100 hours on a 100 mAh coin cell in portable instrumentation. |
| Supply Voltage Range | 2.2 V to 5.5 V - supports direct connection to Li-ion (3.0–4.2 V), 3.3 V logic, or dual ±2.75 V supplies. |
| Common-Mode Input Range | (V−) − 0.1 V to (V+) + 0.1 V - accepts signals beyond rails for single-supply interfacing with transducers. |
| Open-Loop Gain | 126 dB - ensures <1 ppm gain error in precision instrumentation amplifier configurations. |
Pinout & Package
TLV376IDR is packaged in an 8-pin SOIC (D package) with nominal body size 4.90 mm × 3.91 mm, rated for –40°C to +125°C operation. Thermal resistance RθJA is 100.1°C/W, suitable for moderate-power PCB layouts without forced airflow.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT | Amplifier output - rail-to-rail swing within 20 mV of rails into 10 kΩ load; drives ADC input capacitance directly. |
| 2 | –IN | Inverting input - high-impedance CMOS node; requires guarding in high-Z sensor interfaces to minimize leakage error. |
| 3 | +IN | Noninverting input - accepts common-mode voltages up to (V+) + 0.1 V; used for unity-gain buffer configuration. |
| 4 | V− | Negative supply - connects to ground in single-supply systems; must be decoupled with 100 nF ceramic capacitor. |
| 5 | NC | No connection - electrically isolated; no internal bond wire; must remain unconnected per TI specification. |
| 6 | OUT | Output - duplicate pin for thermal and layout symmetry; not internally connected; leave unconnected. |
| 7 | V+ | Positive supply - accepts 2.2–5.5 V; PSRR >84 dB minimizes supply ripple coupling into output signal. |
| 8 | NC | No connection - electrically isolated; no internal bond wire; must remain unconnected per TI specification. |
Key Features
| Feature | Design Value |
|---|---|
| e-trim™ DC precision | 40 μV typical offset and 1.0 μV/°C drift - eliminates need for manual calibration in production test flow. |
| Rail-to-rail I/O | Input extends 100 mV beyond rails; output swings to within 20 mV - maximizes dynamic range in 3.3 V systems. |
| Low 0.1–10 Hz noise | 1.6 μVPP - preserves signal integrity in thermocouple and strain gauge amplification below 10 Hz. |
| Capacitive load drive | Stable with up to 250 pF - directly buffers SAR ADC inputs (e.g., ADS8327) without external isolation resistor. |
| High PSRR | 84–110 dB across 2.2–5.5 V - maintains accuracy when powered from noisy switching regulators or batteries. |
Applications
| ADC Buffering | Medical Instrumentation |
|---|---|
Use Scenario: Driving the analog input of a 16-bit SAR ADC (e.g., ADS8327) in a portable ECG monitor. IC Role / Device Role / Timing Role: Precision unity-gain buffer isolating high-impedance electrode interface from ADC sampling transient.

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA333AIDR | Lower offset (10 μV max), higher IQ (17 μA), same 5.5 MHz GBW and rail-to-rail I/O. | Better for zero-drift-critical dc applications; less suitable for battery-constrained designs due to 21× higher quiescent current. | Choose OPA333AIDR when long-term dc stability outweighs power budget; TLV376IDR preferred for <1 mA system limits. |
| MCP6V81T-E/SN | Higher noise (12 nV/√Hz), lower GBW (1.7 MHz), but zero-drift architecture and 1.6 V min supply. | Superior for sub-2 V operation and ultra-low drift (<0.02 μV/°C); insufficient bandwidth for >100 kHz active filters or fast-settling ADC drivers. | Select MCP6V81T-E/SN for ultra-low-voltage, ultra-low-drift applications; TLV376IDR remains optimal for 2.2–5.5 V, wide-bandwidth needs. |
Compared with OPA333AIDR and MCP6V81T-E/SN, TLV376IDR uniquely balances low noise (8 nV/√Hz), moderate power (815 μA), wide supply range (2.2–5.5 V), and 5.5 MHz bandwidth - making it the most versatile choice for cost-sensitive, battery-operated precision signal chains where neither zero-drift nor ultra-low IQ is mandatory.

FAQ
What is the maximum capacitive load the TLV376IDR can drive stably?
The TLV376IDR is specified to drive up to 250 pF of pure capacitive load in unity-gain configuration without external compensation. This capability is validated in TI's SBOS755 datasheet Figure 16 and enables direct connection to SAR ADC inputs like the ADS8327. For loads exceeding 250 pF, a small series resistor (10–20 Ω) between TLV376IDR output and the capacitance restores stability while preserving dc accuracy.
Does the TLV376IDR support true rail-to-rail input common-mode range?
Yes - the TLV376IDR input common-mode voltage range extends from (V−) − 0.1 V to (V+) + 0.1 V, as confirmed in Section 6.7 of the SBOS755 datasheet. This allows the device to accept signals slightly beyond the supply rails, which is essential for interfacing with transducers whose output may exceed V+ or fall below V− in single-supply systems.
What is the typical quiescent current of the TLV376IDR at 3.3 V supply?
The TLV376IDR draws 815 μA typical quiescent current at 5.5 V, and this value remains stable across its 2.2–5.5 V operating range - including at 3.3 V - as shown in Figure 8 of the SBOS755 datasheet. This consistent low IQ enables predictable battery life estimation in portable 3.3 V designs without derating.
Can the TLV376IDR operate from a single 2.5 V supply?
Yes - the TLV376IDR is fully specified down to 2.2 V single-supply operation, so 2.5 V is well within its recommended range. At 2.5 V, it maintains rail-to-rail input/output swing, 5.5 MHz GBW, and 8 nV/√Hz noise, as confirmed by electrical characteristics tables and typical curves in SBOS755.
Is the TLV376IDR pin-compatible with other op-amps in SOIC-8 packages?
No - TLV376IDR has two NC pins (pins 5 and 8) and a duplicated OUT pin (pin 6), per its SOIC-8 pinout in SBOS755 Section 5. This nonstandard pin assignment means it is not pin-compatible with generic SOIC-8 op-amps like LM358 or TL072. Layout must follow TI's exact TLV376IDR footprint to avoid misconnection.
