Product details
Overview
OPA2376AIYZDT from Texas Instruments is a dual-channel, rail-to-rail input/output precision operational amplifier with e-trim™ technology, 7.5 nV/√Hz input voltage noise at 1 kHz, 5.5 MHz gain-bandwidth product, and 760 μA typical quiescent current per amplifier-designed for low-noise sensor signal conditioning and high-resolution ADC buffering in battery-powered instrumentation.
For engineers reviewing the OPA2376AIYZDT datasheet, OPA2376AIYZDT pinout, OPA2376AIYZDT application, or OPA2376AIYZDT equivalent, key selection criteria include its 5 μV typical offset voltage, 0.8 μVPP 0.1–10 Hz noise, 2.2 V to 5.5 V single-supply operation, and DSBGA-8 package suitability for space-constrained portable designs.
Technical Context
The OPA2376AIYZDT implements a CMOS-based precision op amp architecture with e-trim™ trimming for dc accuracy, delivering 760 μA quiescent current per channel while maintaining 5.5 MHz GBW and 2 V/μs slew rate. Its rail-to-rail input stage supports common-mode voltages from (V−) − 0.1 V to (V+) + 0.1 V, and rail-to-rail output enables full dynamic range utilization down to 20 mV from each rail under 10 kΩ load.
Designed for stability with capacitive loads up to 250 pF in unity-gain configuration, it features internal ESD protection (±4 kV HBM), 90 dB typical CMRR over −40°C to +125°C, and PSRR of 5 μV/V across 2.2 V–5.5 V supply range-enabling direct battery operation without regulation in medical and handheld test equipment.
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 | 7.5 nV/√Hz at 1 kHz - enables <1 μV RMS noise in 10 kHz bandwidth for 16-bit+ ADC drivers |
| Offset Voltage (typ/max) | 5 μV / 25 μV - eliminates need for external nulling in precision sensor front-ends |
| Quiescent Current (per amp) | 760 μA (typ) / 950 μA (max) - allows dual-channel operation below 2 mA total for coin-cell powered devices |
| Supply Voltage Range | 2.2 V to 5.5 V - operates directly from single Li-ion (3.0–4.2 V) or two alkaline cells (2.4–3.2 V) |
| Output Swing (RL = 10 kΩ) | Within 20 mV of rails - preserves >99% dynamic range for 16-bit SAR ADCs with 2.5 V reference |
| 0.1–10 Hz Noise | 0.8 μVPP - ensures sub-LSB error in DC-coupled thermocouple or strain gauge amplifiers |
Pinout & Package
OPA2376AIYZDT is packaged in an 8-pin DSBGA (Die Size Ball Grid Array) with 1.30 mm × 2.30 mm body size and 0.4 mm pitch. The package uses bottom-side solder balls for ultra-compact mounting and thermal performance optimized for PCB heat sinking.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| +IN A | Non-inverting input, Channel A | Accepts signals from (V−) − 0.1 V to (V+) + 0.1 V; low bias current (0.2 pA typ) minimizes leakage errors |
| −IN A | Inverting input, Channel A | Differential pair input node; matched to +IN A for <1 μV input offset drift |
| OUT A | Output, Channel A | Rail-to-rail capable; drives 10 kΩ load to within 20 mV of rails at 25°C |
| V+ | Positive supply | Accepts 2.2–5.5 V; internal regulation ensures stable biasing across supply range |
| V− | Negative supply / ground | Reference for both inputs and outputs; supports true single-supply operation |
| +IN B | Non-inverting input, Channel B | Independent, identical performance to Channel A; enables dual-sensor or differential pair buffering |
| −IN B | Inverting input, Channel B | Electrically isolated from Channel A; channel separation >120 dB at 1 kHz |
| OUT B | Output, Channel B | Full rail-to-rail swing; no crosstalk-induced settling delay when driving separate loads |
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 |
|---|---|---|---|
| OPA2333AIDR | Zero-drift architecture; 0.02 μV/°C max drift vs. OPA2376AIYZDT's 2 μV/°C; higher 175 μA IQ per amp | Better for <85°C DC-critical applications (e.g., precision weight scales); less suitable for wide-temp portable gear | Select OPA2333AIDR only if drift <0.1 μV/°C is mandatory and supply current budget allows 2× increase |
| MCP6V82-E/SN | 1.6 V to 5.5 V supply; 115 μA IQ; 12 nV/√Hz noise; SOIC-8 only-not DSBGA | Lower power but higher noise; unsuitable for 16-bit+ resolution or compact layouts requiring DSBGA | Choose MCP6V82-E/SN only for cost-sensitive, low-speed (<100 kHz), space-tolerant designs where 12 nV/√Hz noise is acceptable |
Compared with OPA2333AIDR and MCP6V82-E/SN, the OPA2376AIYZDT uniquely balances ultra-low noise (7.5 nV/√Hz), low quiescent current (760 μA), rail-to-rail I/O, and DSBGA-8 packaging-making it optimal for high-resolution, battery-powered instrumentation where board area and signal fidelity are co-constrained.

FAQ
What is the maximum operating temperature range for the OPA2376AIYZDT?
The OPA2376AIYZDT is specified for continuous operation from −40°C to +125°C ambient temperature, with absolute maximum junction temperature rated at 150°C. This extended range supports deployment in automotive cabin modules, industrial field sensors, and outdoor medical devices where thermal extremes are encountered. Thermal metrics for the YZD package-including RθJA = 119.2°C/W and RθJB = 27.6°C/W-are documented in the official datasheet SBOS406G.
Does the OPA2376AIYZDT require external compensation for unity-gain stability?
No, the OPA2376AIYZDT is internally compensated and unity-gain stable. It maintains ≥45° phase margin when driving up to 250 pF purely capacitive loads in buffer configuration. For loads exceeding this, a small series resistor (10–20 Ω) between output and capacitive node restores stability without degrading dc accuracy-verified in Figure 16 and Section 7.3.3 of the SBOS406G datasheet. No external capacitor or network is needed for basic operation.
Can the OPA2376AIYZDT be used with a single 3.3 V supply?
Yes, the OPA2376AIYZDT operates fully within its recommended conditions at 3.3 V (V+ = 3.3 V, V− = 0 V). Its rail-to-rail input accepts common-mode voltages from −0.1 V to +3.4 V, and rail-to-rail output swings to within 20 mV of both rails under 10 kΩ load-enabling full utilization of a 3.3 V ADC reference. Quiescent current remains 760 μA per amplifier, and PSRR exceeds 80 dB across this supply point.
What is the input bias current specification for the OPA2376AIYZDT at 85°C?
At TA = 85°C, the input bias current for the OPA2376AIYZDT is ≤10 pA (maximum), consistent with its CMOS input stage design. The typical value remains near 0.2 pA across temperature, and the datasheet confirms IB stays below 10 pA up to +125°C. This ultra-low bias current prevents significant voltage drop across high-impedance sensor sources (e.g., pH electrodes or piezoelectric transducers), preserving signal fidelity without guard rings or T-network compensation.
Is the OPA2376AIYZDT pin-compatible with other dual op amps in DSBGA-8 packages?
No, the OPA2376AIYZDT has a proprietary DSBGA-8 pinout (YZD) that differs from standard dual op amp layouts such as the LMV358 or TLV2372 in DSBGA. Its pin mapping-+IN A, −IN A, OUT A, V+, V−, +IN B, −IN B, OUT B-is unique to the OPAx376 family. Direct replacement requires PCB layout revision; migration paths should verify functional compatibility first, then validate mechanical fit and thermal performance using TI's YZD package drawing SLAS731.
