Product details
Overview
OPA2376AIYZDR from Texas Instruments is a dual-channel, rail-to-rail input/output precision operational amplifier featuring e-trim™ technology for ultra-low offset voltage (5 µV typical), 7.5 nV/√Hz input voltage noise at 1 kHz, and 5.5-MHz gain-bandwidth product - optimized for high-resolution ADC buffering, sensor signal conditioning, and battery-powered instrumentation.
For engineers reviewing the OPA2376AIYZDR datasheet, OPA2376AIYZDR pinout, OPA2376AIYZDR application, or OPA2376AIYZDR equivalent, this page delivers verified electrical specs, DSBGA-8 package mapping, thermal performance data, real-world settling behavior, and validated alternative options for low-noise, low-quiescent-current dual op-amp selection.
Technical Context
The OPA2376AIYZDR implements a CMOS input stage with e-trim™ trimming to achieve 5 µV typical input offset voltage and 0.32 µV/°C max drift over –40°C to +125°C. Its 760 µA per amplifier quiescent current enables operation from 2.2 V to 5.5 V single supply while maintaining rail-to-rail input common-mode range (V– – 0.1 V to V+ + 0.1 V) and output swing within 20 mV of rails (at 10 kΩ load, TA = 25°C).
It delivers 5.5-MHz unity-gain bandwidth and 2 V/µs slew rate with 0.8 µVPP 0.1 Hz–10 Hz noise, supporting stable unity-gain operation into up to 250 pF capacitive loads. Channel separation exceeds 100 dB at 1 kHz, enabling independent dual-channel precision signal paths without crosstalk degradation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain Bandwidth Product | 5.5 MHz - supports stable closed-loop gain ≥1 with ≤180 ns settling to 0.01% for 2-V step. |
| Input Offset Voltage | 5 µV (typ), 25 µV (max) - enables <1 LSB error in 16-bit systems with ±2.5 V full-scale range. |
| Input Voltage Noise | 7.5 nV/√Hz @ 1 kHz - preserves SNR in audio and sensor front-ends with bandwidths up to 100 kHz. |
| Quiescent Current | 760 µA per amplifier (typ) - allows dual-channel precision amplification on coin-cell or Li-ion battery rails. |
| Supply Voltage Range | 2.2 V to 5.5 V - operates directly from single-cell LiFePO₄ (3.2 V) or two alkaline cells (3.0 V) without regulation. |
| Output Swing | Within 20 mV of rails (RL = 10 kΩ, TA = 25°C) - maximizes dynamic range in low-voltage SAR ADC driver applications. |
| CMRR / PSRR | 90 dB / 90 dB (min) - rejects supply ripple and common-mode interference in noisy embedded environments. |
Pinout & Package
OPA2376AIYZDR 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 ball pitch. The package supports high-density PCB layouts and offers low thermal resistance (RθJA = 119.2°C/W, RθJB = 27.6°C/W).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| +IN A (Pin C1) | Non-inverting input, Channel A | Accepts signals from V– – 0.1 V to V+ + 0.1 V; enables true rail-to-rail input operation. |
| –IN A (Pin B1) | Inverting input, Channel A | High-impedance CMOS node (0.2 pA typical bias current); requires matched trace routing for low-offset designs. |
| OUT A (Pin A1) | Output, Channel A | Drives loads down to 2 kΩ; maintains 20-mV rail margin at 10-kΩ load and 25°C. |
| V– (Pin D1) | Negative supply terminal | Reference for both channels; must be decoupled with ≥100 nF ceramic capacitor near package. |
| V+ (Pin A2) | Positive supply terminal | Accepts 2.2–5.5 V; internal ESD diodes clamp inputs to V+ and V– rails (±10 mA absolute max). |
| +IN B (Pin D2) | Non-inverting input, Channel B | Independent input path; channel separation >100 dB prevents crosstalk in dual-sensor interfaces. |
| –IN B (Pin C2) | Inverting input, Channel B | Matched to Channel A for differential pair configurations; same bias current and noise characteristics. |
| OUT B (Pin B2) | Output, Channel B | Unity-gain stable; drives up to 250 pF capacitively without external compensation. |
Key Features
| Feature | Design Value |
|---|---|
| e-trim™ DC precision | Factory-trimmed input offset (5 µV typ) and drift (0.32 µV/°C max) eliminate need for external nulling circuits. |
| Rail-to-rail I/O | Input extends 100 mV beyond supplies; output swings to within 20 mV of rails - maximizes usable signal range at low supply voltages. |
| Low-noise architecture | 7.5 nV/√Hz @ 1 kHz + 0.8 µVPP (0.1–10 Hz) enables sub-16-bit noise floor in precision measurement front-ends. |
| Battery-optimized power | 760 µA per amplifier quiescent current allows dual-channel operation on <1 mA total system budget. |
| Capacitive load drive | Stable into 250 pF at unity gain - eliminates need for isolation resistors when driving ADC input capacitance. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual precision op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA2333AIDR | Zero-drift architecture (0.02 µV/°C drift), lower 1/f noise, but higher 7.5 nV/√Hz broadband noise and 17 µA IQ. | Better for DC-stable integrators or long-duration sensor monitoring; less suitable for battery-constrained portable instruments. | Choose OPA2333AIDR only if drift-critical DC accuracy outweighs quiescent current and noise trade-offs. |
| AD8602ARMZ | Higher 12 nV/√Hz noise, 1.2 µV offset (typ), 1.2 mA IQ, but wider 10-MHz GBW and better capacitive load drive (500 pF). | Preferred for higher-speed active filters or faster-settling ADC drivers where noise is secondary to bandwidth. | Select AD8602ARMZ when >5.5-MHz bandwidth or >250 pF load drive is required, accepting higher power and noise. |
Compared with OPA2376AIYZDR, OPA2333AIDR trades 23× lower drift for 22× higher quiescent current and no improvement in broadband noise, while AD8602ARMZ doubles bandwidth and load drive capability at 1.6× higher noise and 1.6× higher power - making OPA2376AIYZDR optimal for low-noise, low-power dual-channel precision applications.

FAQ
What is the maximum capacitive load the OPA2376AIYZDR can drive stably in unity-gain configuration?
The OPA2376AIYZDR is specified to drive up to 250 pF of pure capacitive load stably in unity-gain configuration without external compensation. This capability is validated in TI's SBOS406G datasheet Figure 16 and enables direct connection to typical SAR ADC input capacitances (e.g., 10–30 pF) with margin for PCB trace capacitance. For loads exceeding 250 pF, a small series resistor (10–20 Ω) at the output restores phase margin while preserving DC accuracy in OPA2376AIYZDR-based designs.
Does the OPA2376AIYZDR support true rail-to-rail input common-mode voltage range?
Yes, the OPA2376AIYZDR supports a rail-to-rail input common-mode voltage range from (V– – 0.1 V) to (V+ + 0.1 V), as confirmed in Section 6.7 of the SBOS406G datasheet. Input offset voltage remains stable across this full range except near the upper limit (V+ – 1 V), where it begins to increase - a behavior explicitly characterized in Figure 23. This enables robust operation in single-supply systems where sensor outputs swing near supply rails, such as in OPA2376AIYZDR-based pH or thermocouple interfaces.
What is the guaranteed input offset voltage specification for OPA2376AIYZDR over temperature?
The OPA2376AIYZDR guarantees a maximum input offset voltage of 25 µV over the full operating temperature range of –40°C to +125°C, with a typical value of 5 µV at 25°C. Its input offset voltage drift is specified at 0.32 µV/°C maximum across –40°C to +125°C (Section 6.7, SBOS406G). These values are achieved via TI's e-trim™ process and are production-tested - ensuring OPA2376AIYZDR meets stringent precision requirements in automotive and industrial control applications without post-assembly calibration.
Can the OPA2376AIYZDR operate from a 2.2-V single supply?
Yes, the OPA2376AIYZDR is fully specified for operation from 2.2 V to 5.5 V single supply (Section 6.3, SBOS406G). At 2.2 V, it maintains rail-to-rail input/output swing, 5.5-MHz gain-bandwidth product, and 760 µA typical quiescent current per amplifier. This makes OPA2376AIYZDR uniquely suited for direct battery operation - for example, powering from a single 2.4-V NiMH cell or a partially discharged 2.5-V Li-ion cell - without voltage regulation, preserving system efficiency and board space.
How does the DSBGA-8 package (YZD) of OPA2376AIYZDR impact thermal performance compared to SOIC-8?
The YZD (DSBGA-8) package of OPA2376AIYZDR delivers superior thermal performance versus SOIC-8: its junction-to-board thermal resistance (RθJB) is 27.6°C/W, compared to 41.0°C/W for SOIC-8 (Section 6.5, SBOS406G). This 33% lower RθJB enables more efficient heat transfer to the PCB, allowing higher sustained output current or operation in compact enclosures. Combined with its 1.30 mm × 2.30 mm footprint, the OPA2376AIYZDR YZD variant supports high-density, thermally robust designs where SOIC-8 would require additional copper pour or thermal vias.
