Product details
Overview
TLV4376IPWR from Texas Instruments is a quad-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, 50 μV typical offset voltage, 5.5 MHz gain-bandwidth product, 2 V/μs slew rate, and operates from 2.2 V to 5.5 V single supply - enabling high-fidelity signal conditioning in battery-powered medical instrumentation and ADC front-ends.
For engineers reviewing the TLV4376IPWR datasheet, TLV4376IPWR pinout, TLV4376IPWR application, or TLV4376IPWR equivalent, key selection criteria include its e-trim™-enhanced dc precision (125 μV max offset), 0.1–10 Hz noise of 2.2 μVPP, 815 μA per amplifier quiescent current, and TSSOP-14 package compatibility with space-constrained PCB layouts.
Technical Context
The TLV4376IPWR implements a CMOS input stage with e-trim™ laser trimming for stable dc performance across temperature (1.0 μV/°C drift) and supply voltage. Its rail-to-rail input extends 100 mV beyond rails, while rail-to-rail output delivers ±20 mV swing from each rail under 10 kΩ load - critical for maximizing dynamic range in single-supply systems.
It features unity-gain stability, supports capacitive loads up to 250 pF in buffer configuration, and maintains >72° phase margin across operating conditions. PSRR (110 dB typ) and CMRR (88 dB typ) remain robust over 2.2–5.5 V supply and –40°C to +125°C, making it suitable for unregulated battery operation without external regulation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain Bandwidth Product | 5.5 MHz - enables stable closed-loop operation up to 100 kHz with G ≥ 10, supporting anti-aliasing filter design for 16-bit+ SAR ADCs. |
| Input Voltage Noise Density | 8 nV/√Hz at 1 kHz - ensures minimal contribution to system noise floor in sensor amplification and precision measurement paths. |
| Offset Voltage (max) | 125 μV - guarantees ≤0.003% gain error in 4-V full-scale instrumentation circuits without calibration. |
| Quiescent Current per Amp | 815 μA - allows four independent channels to operate below 3.3 mA total, extending runtime in portable medical devices. |
| Supply Voltage Range | 2.2 V to 5.5 V - supports direct connection to Li-ion (3.0–4.2 V), coin-cell (3 V), or regulated 3.3 V/5 V rails without LDO overhead. |
| Input Common-Mode Range | (V−) − 0.1 V to (V+) + 0.1 V - permits biasing inputs at mid-supply or ground-referenced signals in single-supply topologies. |
| Slew Rate | 2 V/μs - settles 2-V step within 1.6 μs to 0.1%, meeting timing requirements for multiplexed sensor data acquisition. |
Pinout & Package
TSSOP-14 (PW) package, 5.00 mm × 4.40 mm body size, 0.65 mm pitch, thermally enhanced for industrial ambient operation up to +125°C.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 7, 8, 14 | OUT A/B/C/D | Amplifier output terminals - each drives 10 kΩ load to within ±20 mV of rails; stable with ≥250 pF capacitive load in unity-gain buffer mode. |
| 2, 6, 9, 13 | –IN A/B/C/D | Inverting inputs - high-impedance CMOS nodes (0.3 pA bias current); require guarding in ultra-low-current sensor interfaces. |
| 3, 5, 10, 12 | +IN A/B/C/D | Noninverting inputs - support common-mode voltages 100 mV beyond supply rails, enabling true single-supply signal acquisition. |
| 4 | V+ | Positive supply terminal - accepts 2.2–5.5 V; decoupling capacitor (100 nF) required within 2 mm for PSRR optimization. |
| 11 | V− | Negative supply terminal - referenced to system ground in single-supply use; connects to –VCC in dual-supply configurations. |
Key Features
| Feature | Design Value |
|---|---|
| e-trim™ DC Precision | Laser-trimmed offset (50 μV typ, 125 μV max) and drift (1.0 μV/°C) eliminate need for external nulling in production calibration. |
| Rail-to-Rail I/O | Input range extends 100 mV beyond supplies; output swings to within 20 mV of rails - maximizes usable signal swing in 3.3 V systems. |
| Low 0.1–10 Hz Noise | 2.2 μVPP integrated noise enables accurate DC-coupled amplification of slow-varying biosignals (ECG, EEG) without high-pass filtering. |
| High PSRR & CMRR | 110 dB PSRR and 88 dB CMRR suppress supply ripple and common-mode interference in noisy industrial environments. |
| Unity-Gain Stable | No external compensation required - simplifies layout for gain-of-1 buffers driving ADC inputs or active filters. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA2376AIDR | Lower 4.5 nV/√Hz noise, higher 1.5 mA quiescent current per amp, SOIC-8 dual only - no quad variant. | Preferred where ultra-low noise dominates over power budget; unsuitable for space-constrained quad-channel designs. | Select OPA2376AIDR when noise <5 nV/√Hz is mandatory and board area allows dual SOIC footprint plus two instances. |
| AD8604ARUZ | Higher 12 nV/√Hz noise, wider 2.7–6.0 V supply, 50 μV offset, TSSOP-14 quad - same package but different thermal resistance (RθJA = 120°C/W vs TLV4376's 107.8°C/W). | Better suited for 5 V systems with moderate noise tolerance; less optimal for 2.2–3.3 V battery operation. | Choose AD8604ARUZ if existing design uses 5 V supply and requires pin-compatible drop-in replacement with validated layout reuse. |
Compared with OPA2376AIDR and AD8604ARUZ, TLV4376IPWR uniquely balances sub-10 nV/√Hz noise, <1 mA per amplifier quiescent current, and guaranteed 2.2 V minimum supply - making it the only quad TSSOP option meeting all three constraints for portable precision signal chains.

FAQ
What is the maximum operating temperature range for TLV4376IPWR?
TLV4376IPWR is fully specified from –40°C to +125°C ambient temperature. Its thermal metrics - including RθJA = 107.8°C/W and ψJB = 51.6°C/W - ensure reliable operation in sealed enclosures or high-temperature industrial environments without derating, provided PCB copper area meets TI's recommended layout guidelines.
Does TLV4376IPWR support dual-supply operation?
Yes, TLV4376IPWR supports dual-supply operation from ±1.1 V to ±2.75 V. The device maintains identical electrical specifications (e.g., 8 nV/√Hz noise, 50 μV offset) in dual-supply mode, and its rail-to-rail input allows signals to swing from –VCC to +VCC, making it suitable for legacy bipolar signal chains without redesign.
Can TLV4376IPWR drive heavy capacitive loads without oscillation?
TLV4376IPWR is unity-gain stable and can directly drive up to 250 pF of pure capacitive load. For loads exceeding this, a small series resistor (10–20 Ω) between output and capacitance restores stability while preserving dc accuracy - a technique validated in TI's SBOS755 datasheet Figure 22.
How does e-trim™ technology improve TLV4376IPWR performance?
e-trim™ is TI's proprietary laser trimming process applied during final test that reduces initial offset voltage to 50 μV typical (125 μV max) and limits drift to 1.0 μV/°C. This eliminates post-assembly calibration in production, reduces component count in precision systems, and ensures consistent performance across manufacturing lots and temperature cycles.
Is TLV4376IPWR pin-compatible with other quad op-amps in TSSOP-14?
No - TLV4376IPWR has a unique pinout optimized for quad-channel independence: V+ on pin 4, V− on pin 11, and dedicated inverting/noninverting inputs per channel. It is not pin-compatible with generic quad op-amps like LM324 or MCP6004; PCB layout must follow TI's PW package diagram in SBOS755 Section 5.
