Product details
Overview
OP413FSZ-REEL 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, enabling high-resolution strain gage, RTD, and thermocouple amplification with 5 V or ±15 V supplies.
For engineers reviewing the OP413FSZ-REEL datasheet, OP413FSZ-REEL pinout, OP413FSZ-REEL application, or OP413FSZ-REEL equivalent, this page provides verified specifications, package mapping to 16-lead SOIC_W, real-world application circuits (e.g., load-cell scale amplifier, linearized RTD thermometer), and validated alternative options for precision instrumentation design.
Technical Context
The OP413FSZ-REEL implements a patented bipolar-CMOS hybrid output stage enabling rail-to-rail swing within 1 mV of ground and to within 1 V of V+, critical for maximizing dynamic range in 5 V single-supply systems. Its input common-mode range extends from V– to V+ − 1 V across full supply (4 V to 36 V), supporting true zero-input operation without phase reversal.
Designed for processor-based internal calibration architectures, it guarantees low long-term drift (≤0.8 μV/°C) and ultra-low 0.1 Hz–10 Hz noise (120 nV p-p), allowing digital correction of offset/gain while preserving analog integrity against thermal and aging effects.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain Bandwidth Product | 3.4 MHz - supports stable closed-loop gain ≥10 up to 340 kHz, suitable for anti-aliasing and sensor signal conditioning. |
| Voltage Noise Density | 4.7 nV/√Hz @ 1 kHz - enables resolution of sub-μV signals in strain gage bridges and RTD interfaces. |
| Offset Voltage Drift | 0.2 μV/°C (typ), ≤0.8 μV/°C (max) - ensures <1 μV total drift over 0°C–70°C, critical for uncalibrated industrial temperature sensing. |
| Input Common-Mode Range | V– to V+ − 1 V - allows direct interfacing to grounded sensors (e.g., 3-wire RTDs) without level-shifting circuitry. |
| Output Swing (RL = 2 kΩ) | Within 1 V of V+ and within 1 mV of V– - maximizes usable signal headroom in 5 V systems (e.g., 0.001 V to 4.0 V output range). |
| Supply Voltage Range | ±2 V to ±18 V or +4 V to +36 V - supports dual-supply lab equipment and single-supply portable instrumentation. |
| Channel Separation | 105 dB @ 1 kHz - prevents crosstalk between channels in multi-sensor data acquisition (e.g., simultaneous load cell & thermocouple reads). |

FAQ
What is the maximum supply voltage for OP413FSZ-REEL?
The absolute maximum supply voltage for OP413FSZ-REEL is ±18 V for dual supplies or +36 V for single-supply operation, as specified in Table 3 of the Rev. F datasheet. Continuous operation beyond these limits risks permanent damage. For reliable long-term performance, Analog Devices recommends staying within the recommended operating range of ±2 V to ±18 V or +4 V to +36 V.
Does OP413FSZ-REEL support true rail-to-rail input and output?
OP413FSZ-REEL supports rail-to-rail output swing (within 1 mV of V– and within 1 V of V+) but has a limited input common-mode range: V– to V+ − 1 V. It does not support full rail-to-rail input-inputs cannot reach V+-but this design enables superior PSRR and CMRR versus true RRO op-amps, making it ideal for sensor interfaces where the signal stays near ground.
Can OP413FSZ-REEL be used with a 3.3 V supply?
OP413FSZ-REEL is not characterized or guaranteed for operation at 3.3 V. Its minimum specified single-supply voltage is +4 V. At 3.3 V, key parameters-including output swing, CMR, and gain bandwidth-fall outside datasheet limits. For 3.3 V systems, consider alternatives like AD8604 or OPA4340 explicitly rated down to 2.7 V.
How does the patented output stage of OP413FSZ-REEL improve performance?
The patented bipolar-CMOS hybrid output stage in OP413FSZ-REEL enables output swing within 1 mV of V– (ground), far exceeding standard bipolar op-amps (~10 mV). This eliminates the need for negative supplies in single-ended 5 V systems and increases effective dynamic range by up to 10 mV-critical for 16-bit+ ADCs in precision weigh scales and temperature transducers.
Is OP413FSZ-REEL pin-compatible with other OPx13 family members?
No. OP413FSZ-REEL uses a 16-lead SOIC_W package with unique pinout (e.g., V+ on Pin 4, V– on Pin 13), whereas OP113 (8-pin SOIC_N) and OP213 (8-pin SOIC_N) have different pin counts and assignments. Direct PCB replacement is not possible; layout redesign is required when migrating between OPx13 variants.
