Product details
Overview
OP413ESZ from Analog Devices is a quad, low-noise, low-drift, single-supply operational amplifier optimized for precision analog signal conditioning in battery-powered and internally calibrated systems. It delivers 4.7 nV/√Hz voltage noise density at 1 kHz, 0.2 μV/°C max offset drift, and 3.4 MHz gain bandwidth product while operating from 4 V to 36 V supplies. It is used in high-resolution strain gage amplifiers, RTD thermometers, and sigma-delta ADC/DAC interfaces where rail-to-rail input (to within 1 V of V+) and output (to within 1 V of V+ and to ground) are critical.
For engineers reviewing the OP413ESZ datasheet, OP413ESZ pinout, OP413ESZ application, or OP413ESZ equivalent, this page provides verified specifications, package-confirmed pin functions, real-world use cases in load-cell and temperature transducer circuits, and two validated alternative op-amps with documented performance trade-offs.
Technical Context
The OP413ESZ belongs to the OPx13 family designed specifically for unipolar supply operation (4 V to 36 V), featuring a patented bipolar-CMOS hybrid output stage enabling true zero-volt output swing - unlike conventional bipolar op-amps limited to ~10 mV above ground. Its input common-mode range extends from V− to within 1 V of V+ across full supply and temperature ranges.
It maintains precision under single-supply constraints: guaranteed 125–275 μV max input offset voltage (F grade), 0.2–1.5 μV/°C drift, and 93–106 dB CMRR at 5 V. The device is unity-gain stable, exhibits no phase reversal when inputs stay within supply rails, and supports 600 Ω load drive with ±30 mA short-circuit current capability.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 4 V to 36 V single supply - enables direct interface with 5 V or 12 V embedded systems without dual-rail generation. |
| Voltage Noise Density | 4.7 nV/√Hz @ 1 kHz - enables resolution of sub-microvolt signals in strain gage and RTD bridges. |
| Offset Drift | 0.2 μV/°C typical - minimizes calibration drift over industrial temperature range (−40°C to +85°C). |
| Gain Bandwidth Product | 3.4 MHz - supports stable closed-loop gain ≥10 up to ~300 kHz for anti-aliasing and sensor signal filtering. |
| Input Common-Mode Range | V− to (V+ − 1 V) - accommodates ground-referenced sensors without level-shifting circuitry. |
| Output Swing (5 V, RL = 600 Ω) | 0.008 V to 3.9 V - delivers >78% of full-scale dynamic range in 5 V systems, maximizing ADC utilization. |
| CMRR | 93 dB min @ 5 V - rejects power supply ripple and shared-ground noise in multi-channel instrumentation. |
Pinout & Package
OP413ESZ is housed in a 16-lead wide-body SOIC_W package (suffix 'S' per Analog Devices ordering guide), with thermal resistance θJA = 92°C/W and θJC = 27°C/W. Pin 1 is top-left corner marker; pins 8 and 9 are NC (no connect).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT A | Amplifier A output - drives loads down to 600 Ω with rail-to-rail swing capability. |
| 2 | –IN A | Inverting input of Amp A - accepts differential signals from bridge sensors or feedback networks. |
| 3 | +IN A | Non-inverting input of Amp A - connects to reference, sensor, or buffered signal source. |
| 4 | V+ | Positive supply rail - accepts 4 V to 36 V single supply; decoupling capacitor required. |
| 5 | +IN B | Non-inverting input of Amp B - electrically isolated from other channels; shares V+ and V−. |
| 6 | –IN B | Inverting input of Amp B - supports independent gain configuration per channel. |
| 7 | OUT B | Amplifier B output - identical performance to OUT A; enables dual-channel signal conditioning. |
| 10 | OUT C | Amplifier C output - fully independent channel; usable for multi-sensor or redundancy designs. |
| 11 | –IN C | Inverting input of Amp C - supports differential or single-ended configurations. |
| 12 | +IN C | Non-inverting input of Amp C - referenced to same V− as all channels. |
| 13 | V− | Negative supply rail - tied to ground in single-supply operation; must be stable and low-impedance. |
| 14 | +IN D | Non-inverting input of Amp D - completes quad-channel functionality for multi-signal acquisition. |
| 15 | –IN D | Inverting input of Amp D - supports independent feedback loop per channel. |
| 16 | OUT D | Amplifier D output - matches electrical specs of other outputs; enables 4× simultaneous analog paths. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail output swing to ground | Enables true 0 V output in 5 V systems - eliminates need for negative rail in portable instrumentation. |
| No phase reversal on input overvoltage | Prevents catastrophic latch-up or signal inversion when sensor transients exceed V− or V+, improving system robustness. |
| Low 1/f noise (120 nV p-p, 0.1–10 Hz) | Reduces baseline drift in slow-response temperature and weight measurements, enhancing long-term stability. |
| Guaranteed 0.2 μV/°C drift (typical) | Allows factory calibration without recalibration across −40°C to +85°C ambient - reduces BOM cost and test time. |
| Unity-gain stable with 1 kΩ load | Supports direct buffer configurations without external compensation - simplifies PCB layout and reduces component count. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AD8628ARZ | Zero-drift auto-zero architecture; 0.005 μV/°C drift vs. OP413ESZ's 0.2 μV/°C; higher 1/f noise (0.1–10 Hz: 0.5 μV p-p). | Better for DC-critical applications like precision references; less suitable for AC-coupled strain gage signals due to chopper-induced artifacts. | Select AD8628ARZ only when sub-μV/°C drift dominates design requirements and bandwidth ≤100 kHz suffices. |
| OPA2188AIDR | Zero-drift, 850 kHz GBW, 0.005 μV/°C drift; lower noise floor (5.5 nV/√Hz) but higher 0.1–10 Hz noise (250 nV p-p). | Superior for low-frequency thermocouple amps; inferior for fast-settling sigma-delta DAC buffers due to slower slew rate (0.45 V/μs vs. 0.8 V/μs). | Choose OPA2188AIDR when long-term DC stability outweighs transient response needs and supply is ≥4.5 V. |
Compared with AD8628ARZ and OPA2188AIDR, OP413ESZ offers superior balance of low broadband noise, fast settling (9 μs to 0.01%), and true rail-to-rail output in 4 V systems - making it optimal for multi-channel, battery-constrained, medium-bandwidth sensor interfaces.

FAQ
What is the maximum supply voltage for OP413ESZ?
The absolute maximum supply voltage for OP413ESZ is ±18 V, meaning it supports single-supply operation up to 36 V or dual-supply operation up to ±18 V. Per the datasheet Absolute Maximum Ratings table, exceeding ±18 V risks permanent damage. For reliable operation, Analog Devices specifies 4 V to 36 V single-supply range, with tested performance at 5 V and ±15 V. OP413ESZ maintains its low-noise and low-drift characteristics across this full range.
Does OP413ESZ support rail-to-rail input and output?
OP413ESZ supports rail-to-rail output swing - it drives to within 1 V of V+ and to ground (V−) under 600 Ω load. Its input common-mode range extends from V− to within 1 V of V+, but not fully rail-to-rail on the high side. This allows direct interfacing with ground-referenced sensors while maintaining precision near the positive rail. The datasheet confirms this behavior across −40°C to +85°C and multiple supply voltages, including 5 V and ±15 V.
What is the guaranteed input offset voltage for OP413ESZ?
For the F-grade OP413ESZ, the input offset voltage is guaranteed to be 125–275 μV at 25°C and 175–400 μV over the full −40°C to +85°C temperature range (Table 2, Rev. F datasheet). This specification applies specifically to the OP413 variant - not OP113 or OP213 - and is measured with VS = 5.0 V. The tighter 125–275 μV band reflects production screening for enhanced precision.
Can OP413ESZ be used in single-supply 3.3 V applications?
No - OP413ESZ is not characterized or guaranteed for 3.3 V operation. Its minimum specified supply voltage is 4 V (single supply) per the Electrical Characteristics tables. At 3.3 V, key parameters including output swing, CMRR, and gain bandwidth degrade beyond datasheet limits. For 3.3 V systems, Analog Devices recommends alternatives such as AD8605 or ADA4522-1, which are explicitly rated down to 2.7 V.
What package type is OP413ESZ supplied in?
OP413ESZ is supplied in a 16-lead wide-body SOIC_W package (body width 7.5 mm), identified by suffix 'S' in the Analog Devices ordering guide. Thermal resistance is θJA = 92°C/W and θJC = 27°C/W. This package differs from the 8-lead SOIC_N used for OP113/OP213 and the 8-lead PDIP used in through-hole variants. Pin 1 is marked with a notch or dot; pins 8 and 9 are no-connect.
