Product details
Overview
TLV2376IDGKT 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 - enabling high-fidelity signal conditioning in battery-powered instrumentation and ADC front-ends.
For engineers reviewing the TLV2376IDGKT datasheet, TLV2376IDGKT pinout, TLV2376IDGKT application, or TLV2376IDGKT equivalent, this page provides verified electrical specifications, VSSOP-8 package details, dual-channel functional context, production-distribution data for offset voltage, and validated alternatives for precision op-amp selection in medical, solar, and test equipment designs.
Technical Context
The TLV2376IDGKT integrates 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, with rail-to-rail input extending 100 mV beyond supply rails and rail-to-rail output swing within 10–20 mV of each rail. Its CMOS architecture supports single-supply operation from 2.2 V to 5.5 V (±1.1 V to ±2.75 V) and exhibits 88 dB typical CMRR and 110 dB PSRR.
It features unity-gain stability, 2 V/μs slew rate, 1.6 μs settling time to 0.1%, and drives up to 250 pF capacitive load in unity-gain configuration. Channel separation is specified at 0.5 mV/V (dc), confirming robust dual-channel isolation for simultaneous signal paths without crosstalk-induced error.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain Bandwidth Product | 5.5 MHz - enables stable closed-loop gain up to 55× at 100 kHz or unity-gain buffer operation at full bandwidth. |
| Input Voltage Noise Density | 8 nV/√Hz at 1 kHz - ensures minimal added noise in sensor amplification and high-resolution ADC driving. |
| Offset Voltage (typ) | 40 μV - reduces dc error in precision gain stages, critical for 16-bit+ data acquisition systems. |
| Quiescent Current (per channel) | 815 μA - supports always-on, low-power portable instrumentation without thermal derating. |
| Supply Voltage Range | 2.2 V to 5.5 V single supply - allows direct operation from Li-ion, 3.3 V, or 5 V rails without regulation. |
| Input Common-Mode Range | (V−) − 0.1 V to (V+) − 1.3 V - supports sensing near ground and rail in single-supply configurations. |
| Output Swing (RL = 10 kΩ) | Within 10–20 mV of rails - maximizes dynamic range when interfacing with SAR or delta-sigma ADCs. |
Pinout & Package
VSSOP-8 (DGK) package: 3.00 mm × 3.00 mm body, 0.65 mm lead pitch, thin-profile surface-mount design optimized for space-constrained PCB layouts in portable and industrial modules.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT A | Amplifier A output - drives external load or next-stage input with rail-to-rail swing and 150 Ω open-loop output impedance. |
| 2 | −IN A | Inverting input, channel A - forms feedback node in inverting configurations; accepts signals down to V− − 0.1 V. |
| 3 | +IN A | Noninverting input, channel A - used in noninverting buffers and active filters; common-mode range extends beyond rails. |
| 4 | V− | Negative supply terminal - referenced for both channels; must be connected to system ground or negative rail. |
| 5 | +IN B | Noninverting input, channel B - electrically isolated from channel A; enables independent dual-path signal processing. |
| 6 | −IN B | Inverting input, channel B - supports differential pair or separate gain stage without shared input nodes. |
| 7 | OUT B | Amplifier B output - identical performance to OUT A; channel separation limits crosstalk to ≤0.5 mV/V (dc). |
| 8 | V+ | Positive supply terminal - powers both amplifiers; PSRR of 110 dB suppresses supply ripple in noisy environments. |
Key Features
| Feature | Design Value |

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA2376AIDGKT | Identical pinout and specs, but uses auto-zero architecture instead of e-trim™ - 0.1 μV/°C drift vs 1.0 μV/°C, 5.2 MHz GBW vs 5.5 MHz. | Better for ultra-low-drift DC-critical apps (e.g., weigh scales); slightly lower bandwidth may limit high-frequency filtering. | Select OPA2376AIDGKT when drift <0.2 μV/°C is mandatory and bandwidth margin >300 kHz remains. |
| AD8628ARZ-REEL7 | Zero-drift architecture, 1 μV max offset, 2.5 MHz GBW, 1.5 V/μs slew rate, SOIC-8 only - no VSSOP option. | Superior dc accuracy for calibration equipment; insufficient bandwidth/slew for >100 kHz signal chains or fast-settling ADC drivers. | Choose AD8628ARZ-REEL7 for lab-grade instrumentation where dc stability outweighs ac performance and board space. |
Compared with TLV2376IDGKT, OPA2376AIDGKT offers tighter drift control at minor bandwidth cost, while AD8628ARZ-REEL7 delivers zero-drift dc precision but lacks the speed and VSSOP footprint needed for compact, wideband portable designs.

FAQ
What is the maximum capacitive load the TLV2376IDGKT can drive stably in unity-gain configuration?
The TLV2376IDGKT is specified to drive up to 250 pF of pure capacitive load stably in unity-gain buffer configuration, as confirmed in the TI SBOS755 datasheet Figure 16 and Section 7.3.3. For loads exceeding 250 pF, adding a 10–20 Ω series resistor at the output (RS) restores stability without degrading dc accuracy - a technique validated in TI application note SLOA058. This capability makes TLV2376IDGKT suitable for direct connection to anti-aliasing filters and ADC input capacitors.
Does the TLV2376IDGKT support true rail-to-rail input common-mode voltage?
Yes - the TLV2376IDGKT supports rail-to-rail input with common-mode voltage range from (V−) − 0.1 V to (V+) − 1.3 V, per Section 6.7 of the SBOS755 datasheet. This means it accepts signals 100 mV below ground (in single-supply use) and up to 1.3 V below V+, enabling full utilization of input range in 3.3 V systems. However, parameters like offset voltage and CMRR degrade outside (V−) to (V+) − 1.3 V, so design margins must respect that boundary for precision operation.
What is the typical quiescent current per channel for TLV2376IDGKT at 5.5 V supply?
The TLV2376IDGKT draws 815 μA typical quiescent current per amplifier channel 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 (2.2–5.5 V), with maximum 1200 μA per channel. This low IQ enables multi-channel precision amplification in energy-constrained applications like handheld meters and wireless sensors without thermal throttling.
How does the e-trim™ technology in TLV2376IDGKT improve production yield and system accuracy?
e-trim™ is TI's proprietary wafer-level trimming process that adjusts internal offset voltage during final test, reducing typical input offset to 40 μV and maximum to 100 μV - significantly tighter than untrimmed CMOS op-amps. This eliminates need for external nulling circuits or post-assembly calibration, improving manufacturing yield and ensuring consistent dc accuracy across batches. The TLV2376IDGKT's 1.0 μV/°C drift specification further guarantees long-term stability in field-deployed equipment like solar monitoring units and portable diagnostics.
Is TLV2376IDGKT pin-compatible with other dual op-amps in VSSOP-8 package?
TLV2376IDGKT uses standard VSSOP-8 pinout (DGK) matching industry conventions: pins 1/7 = outputs, 2/6 = inverting inputs, 3/5 = noninverting inputs, 4 = V−, 8 = V+. It is pin-compatible with TI's OPA2376AIDGKT and generic dual op-amps using this layout (e.g., MCP6022, ADA4077-2), but functional equivalence requires verification of bandwidth, noise, and input structure - especially since TLV2376IDGKT is e-trim™ CMOS while others may be auto-zero or bipolar. Always validate loop stability and dc error in target circuit.
