Product details
Overview
TLV2376IDGKR from Texas Instruments is a dual-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 815 μA typical quiescent current per channel, operating from 2.2 V to 5.5 V single supply. It is used in ADC buffering, sensor signal conditioning, and handheld test equipment where dc precision and ac fidelity are critical.
For engineers reviewing the TLV2376IDGKR datasheet, TLV2376IDGKR pinout, TLV2376IDGKR application, or TLV2376IDGKR equivalent, this page provides verified specifications, validated dual-amplifier pin functions, real-world use cases in precision analog front-ends, and confirmed alternative parts with documented parameter differences - all aligned to TI's SBOS755 production data sheet.
Technical Context
The TLV2376IDGKR integrates e-trim™ technology for factory-trimmed dc precision, achieving 40 μV typical input offset and 1.0 μV/°C drift over –40°C to +125°C. Its CMOS input stage delivers 0.3 pA typical input bias current and rail-to-rail common-mode range (V– – 0.1 V to V+ + 0.1 V), enabling direct interfacing with SAR ADCs and unregulated battery supplies.
It features unity-gain stability, 2 V/μs slew rate, and drives ≥250 pF capacitive loads in unity-gain configuration. PSRR (110 dB typical) and CMRR (88 dB typical) remain robust across its full 2.2–5.5 V supply range, supporting high-accuracy measurements in noisy, single-supply environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain Bandwidth Product | 5.5 MHz - supports stable closed-loop operation up to 100 kHz with gain ≥10, suitable for anti-aliasing filters before 16-bit+ ADCs. |
| Input Voltage Noise Density | 8 nV/√Hz at 1 kHz - enables sub-16-bit noise floor preservation in precision sensor amplification chains. |
| Input Offset Voltage (typ) | 40 μV - reduces dc error to <0.1% of full-scale in 4-V output ranges, critical for medical instrumentation calibration. |
| Quiescent Current per Channel | 815 μA - allows dual-channel precision amplification in battery-powered handheld test gear with multi-day runtime. |
| Supply Voltage Range | 2.2 V to 5.5 V - operates directly from Li-ion (3.0–4.2 V) or two alkaline cells (2.4–3.2 V) without regulation. |
| Common-Mode Input Range | V– – 0.1 V to V+ + 0.1 V - accepts signals beyond rails, simplifying level-shifting in single-supply data acquisition systems. |
| Output Swing (RL = 10 kΩ) | Within 10 mV of rails - maximizes dynamic range when driving successive-approximation ADC inputs referenced to VDD/2. |
Pinout & Package
The TLV2376IDGKR is housed in an 8-pin VSSOP (DGK) package measuring 3.00 mm × 3.00 mm, with exposed thermal pad for enhanced power dissipation in compact PCB layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT A | Amplifier A output - drives external load or next-stage input; rail-to-rail swing supports full utilization of ADC reference range. |
| 2 | –IN A | Inverting input, channel A - connects to feedback network in inverting configurations or sensor bridge outputs. |
| 3 | +IN A | Noninverting input, channel A - accepts high-impedance sensor signals (e.g., thermocouples, strain gauges) with minimal loading. |
| 4 | V– | Negative supply terminal - tied to ground in single-supply systems; must be decoupled with 100 nF ceramic capacitor. |
| 5 | +IN B | Noninverting input, channel B - independent input for dual-signal paths (e.g., differential sensor pairs or stereo audio preamps). |
| 6 | –IN B | Inverting input, channel B - used for matched gain-setting in dual-channel active filters or instrumentation topologies. |
| 7 | OUT B | Amplifier B output - provides second independent analog path; electrically isolated from OUT A to prevent crosstalk. |
| 8 | V+ | Positive supply terminal - accepts 2.2–5.5 V; PSRR >110 dB ensures immunity to supply ripple in mixed-signal PCBs. |
Key Features
| Feature | Design Value |
|---|---|
| e-trim™ DC Precision | Factory-trimmed offset (40 μV typ) and drift (1.0 μV/°C) eliminate need for external nulling circuits in production calibration. |
| Rail-to-Rail I/O | Full input common-mode range (V– – 0.1 V to V+ + 0.1 V) and output swing within 10 mV of rails maximize signal headroom in 3.3-V systems. |
| Low 0.1–10 Hz Noise | 1.6 μVPP integrated noise enables stable baseline measurement in ECG and pressure transducer front-ends. |
| Capacitive Load Drive | Stable with ≥250 pF pure capacitive load at unity gain - eliminates need for isolation resistors when driving ADC sample capacitors. |
| High PSRR & CMRR | 110 dB PSRR and 88 dB CMRR suppress supply noise and common-mode interference in industrial sensor nodes. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA2333AIDGKR | Lower offset drift (0.02 μV/°C vs. 1.0 μV/°C) but higher quiescent current (17 μA vs. 815 μA); same 5.5 MHz GBW. | Better for ultra-stable dc-coupled systems (e.g., precision weigh scales); less suitable for battery-constrained portable gear. | Select OPA2333AIDGKR only if long-term drift dominates power budget constraints. |
| AD8605ARMZ-REEL | Higher noise (12 nV/√Hz vs. 8 nV/√Hz), lower GBW (10 MHz vs. 5.5 MHz), and no e-trim (150 μV max offset vs. 100 μV max). | Acceptable for general-purpose instrumentation where cost is prioritized over low-frequency noise performance. | Choose AD8605ARMZ-REEL when legacy design reuse or distributor stock availability outweighs noise-sensitive requirements. |
Compared with OPA2333AIDGKR and AD8605ARMZ-REEL, TLV2376IDGKR uniquely balances ultra-low 1/f noise, factory-trimmed dc accuracy, and sub-mA power - making it optimal for cost-sensitive, battery-powered precision analog systems requiring both ac fidelity and dc stability.

FAQ
What is the maximum capacitive load the TLV2376IDGKR can drive stably in unity-gain configuration?
The TLV2376IDGKR can drive up to 250 pF of pure capacitive load stably in unity-gain configuration without external compensation. This capability is confirmed in TI's SBOS755 datasheet Figure 16 and Section 7.3.3. For loads exceeding 250 pF, a small series resistor (10–20 Ω) between the output and capacitive node restores phase margin while preserving dc accuracy. TLV2376IDGKR's internal compensation ensures no external components are needed for standard ADC input buffering.
Does the TLV2376IDGKR support true rail-to-rail input common-mode voltage range?
Yes - the TLV2376IDGKR accepts input voltages from V– – 0.1 V to V+ + 0.1 V, extending 100 mV beyond both supply rails. This is explicitly specified in Section 6.7 (Electrical Characteristics) of the SBOS755 datasheet under "INPUT VOLTAGE RANGE". The amplifier maintains low offset and high CMRR across this full range, making TLV2376IDGKR suitable for single-supply sensor interfaces where signals may approach or slightly exceed supply rails.
What is the typical quiescent current per channel for TLV2376IDGKR at 5.5 V supply?
The typical quiescent current per channel for TLV2376IDGKR is 815 μA at VS = 5.5 V, TA = 25°C, as stated in Section 6.7 (Electrical Characteristics) of the SBOS755 datasheet. This value remains stable across temperature (–40°C to +125°C) and supply voltage (2.2–5.5 V), with maximum specified at 1200 μA. TLV2376IDGKR's low IQ enables dual-channel precision amplification in space- and power-constrained portable instruments.
How does the e-trim™ technology in TLV2376IDGKR improve system-level accuracy?
e-trim™ technology performs post-package, wafer-level trimming of input offset voltage and drift during final test, reducing typical VOS to 40 μV and dVOS/dT to 1.0 μV/°C. Unlike laser trimming, e-trim™ compensates for molding-induced stress shifts, ensuring stability over time and temperature. This eliminates manual calibration in TLV2376IDGKR-based systems such as portable medical sensors and solar monitoring units, directly improving first-pass yield and long-term measurement repeatability.
Is TLV2376IDGKR pin-compatible with other dual op-amps in VSSOP-8 packages?
No - TLV2376IDGKR has a non-standard pinout among dual VSSOP-8 op-amps: OUT A (pin 1), –IN A (pin 2), +IN A (pin 3), V– (pin 4), +IN B (pin 5), –IN B (pin 6), OUT B (pin 7), V+ (pin 8). This differs from industry-standard dual op-amps like LMV722 or OPA2333, which place V+ at pin 8 but assign different functions to pins 1–3 and 5–7. Direct replacement requires PCB layout revision; TLV2376IDGKR's pinout is fixed per TI's DGK package definition in SBOS755.
