Product details
Overview
TLV2376IDR 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 TLV2376IDR datasheet, TLV2376IDR pinout, TLV2376IDR application, or TLV2376IDR equivalent, key selection considerations include its e-trim™-enabled dc precision, 2.2 V to 5.5 V single-supply operation, –40°C to +125°C temperature range, and compatibility with SAR ADC driving, active filtering, and sensor signal chains requiring <2.2 μVPP 0.1–10 Hz noise.
Technical Context
The TLV2376IDR employs CMOS input stage architecture with TI's e-trim™ technology for factory-trimmed offset and drift, achieving 1.0 μV/°C max dVOS/dT over –40°C to +125°C. Its rail-to-rail input extends 100 mV beyond supply rails, and rail-to-rail output swings within 10–20 mV of each rail under 10 kΩ load.
Designed for unity-gain stability, it supports capacitive loads up to 250 pF in buffer configuration and maintains 72° phase margin. PSRR (110 dB typ) and CMRR (88 dB typ) remain robust across 2.2–5.5 V supply and full temperature range, making it suitable for unregulated battery systems.

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA2333AIDR | Chopper-stabilized (0.02 μV/°C drift), higher IQ (17 μA), lower noise floor (0.65 μVPP), but 350 kHz GBW. | Better for ultra-low-drift DC applications (e.g., precision weigh scales); unsuitable for >100 kHz signal paths. | Choose OPA2333AIDR when sub-μV/°C drift dominates over bandwidth and power; avoid when driving SAR ADCs above 200 kSPS. |
| AD8628ARZ-REEL7 | Zero-drift architecture (0.005 μV/°C), 2.5 MHz GBW, 1.2 mA IQ, 0.55 μVPP noise, but only single-channel in SOIC-8. | Preferred for single-ended high-precision DC gain stages where dual-channel integration is not required. | Choose AD8628ARZ-REEL7 for highest dc accuracy in single-channel roles; TLV2376IDR remains optimal for cost-sensitive dual-path designs. |
Compared with OPA2333AIDR and AD8628ARZ-REEL7, TLV2376IDR provides the best balance of dual-channel integration, 5.5 MHz bandwidth, 815 μA power, and 40 μV offset - making it the preferred choice for portable, multi-sensor systems requiring both precision and speed without chopper-induced switching artifacts.

FAQ
What is the maximum capacitive load the TLV2376IDR can drive stably in unity-gain configuration?
The TLV2376IDR is specified to drive up to 250 pF of pure capacitive load stably in unity-gain buffer configuration. For larger loads, a small series resistor (10–20 Ω) between the output and capacitor improves phase margin without degrading dc accuracy - a technique validated in TI's SBOS755 datasheet Figure 22. This capability makes TLV2376IDR well-suited for anti-aliasing filter and ADC input buffering applications.
Does the TLV2376IDR support dual-supply operation, and what are the limits?
Yes, the TLV2376IDR supports dual-supply operation from ±1.1 V to ±2.75 V (i.e., total supply voltage 2.2 V to 5.5 V), matching its single-supply range. The device maintains full rail-to-rail input/output swing, 40 μV typical offset, and 8 nV/√Hz noise across this entire range. Absolute maximum ratings allow ±3.5 V supplies, but operation outside ±2.75 V is not characterized and may degrade performance.
How does the e-trim™ technology in TLV2376IDR improve production yield and system accuracy?
TI's e-trim™ technology performs laser or fuse-based trimming of internal offset compensation networks during final wafer test, reducing initial input offset voltage to 40 μV typical (vs. >1 mV in untrimmed CMOS op-amps) and limiting drift to 1.0 μV/°C. This eliminates post-assembly calibration in most applications and ensures consistent 16-bit-equivalent accuracy across temperature - directly improving yield in high-volume sensor module manufacturing.
Can TLV2376IDR be used to drive a 24-bit SAR ADC such as the ADS1262?
Yes, TLV2376IDR is explicitly recommended for driving high-resolution SAR ADCs including 24-bit converters. Its 5.5 MHz GBW, 2 V/μs slew rate, 1.6 μs 0.1% settling time, and 2.2 μVPP 0.1–10 Hz noise meet the dynamic and noise requirements of precision delta-sigma and SAR ADCs. TI's SBOS755 datasheet Figure 27 demonstrates TLV2376IDR driving the ADS8327, and the same performance envelope applies to ADS1262 front-end buffering.
What is the thermal resistance (RθJA) of TLV2376IDR in SOIC-8 package, and how does it affect power dissipation?
The TLV2376IDR in SOIC-8 (D package) has a junction-to-ambient thermal resistance (RθJA) of 111.1°C/W, as specified in Section 6.5 of SBOS755. At 815 μA per channel and 5.5 V supply, total power dissipation is ~9 mW, resulting in <1°C junction rise above ambient - well within safe operating limits even in sealed enclosures. This low self-heating preserves offset stability and noise performance in precision applications.
