Product details
Overview
OP213FSZ-REEL7 from Analog Devices is a dual-channel, low-noise, low-drift, single-supply operational amplifier optimized for precision analog signal conditioning in battery-powered and industrial instrumentation. 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 and RTD amplification with 5 V supply operation.
For engineers reviewing the OP213FSZ-REEL7 datasheet, OP213FSZ-REEL7 pinout, OP213FSZ-REEL7 application, or OP213FSZ-REEL7 equivalent, key selection criteria include rail-to-rail output swing (to within 8 mV of ground at 5 V), input common-mode range extending to V–, guaranteed 100 μV max offset voltage (F grade), and phase reversal protection-critical for uncalibrated sensor front-ends.
Technical Context
The OP213FSZ-REEL7 implements a patented bipolar-CMOS hybrid output stage that enables true zero-volt output swing under single-supply conditions-achieving ≤8 mV above V– at 5 V/600 Ω load-while maintaining >100 dB CMRR over 0 V to 4 V input range. Its input stage uses matched PNP transistors to minimize drift and 1/f noise.
It operates across ±4 V to ±18 V dual supplies or 4 V to 36 V single supply, with guaranteed performance over –40°C to +85°C. The device is unity-gain stable, exhibits no phase reversal when inputs stay within supply rails, and supports 1 V/μs min slew rate with 9 μs settling to 0.01% for 10 V step.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Offset Voltage | 100 μV max (F grade, 25°C); ensures ≤0.1% gain error in 100× gain sensor interfaces without trimming. |
| Offset Drift | 0.2 μV/°C typ, ≤0.8 μV/°C max; enables <±0.5°C RTD measurement accuracy over full industrial temperature range. |
| Voltage Noise Density | 4.7 nV/√Hz @ 1 kHz; 4× lower than typical precision op amps-critical for sub-μV strain gage signals. |
| Gain Bandwidth Product | 3.4 MHz; supports stable closed-loop gain ≥10 up to ~300 kHz for anti-aliasing filter integration. |
| Output Swing (5 V) | 0 V to 3.9 V @ 600 Ω; delivers >78% of full rail-to-rail dynamic range-maximizes ADC utilization in 5 V systems. |
| Common-Mode Rejection | 93 dB min (0–4 V, 25°C); rejects power supply ripple and shared-ground interference in multi-sensor PCB layouts. |
| Supply Current/Amplifier | 1.6 mA typ @ 5 V; enables dual-channel precision amplification in <3.3 mW total power budget. |
Pinout & Package
OP213FSZ-REEL7 is housed in an 8-lead narrow-body SOIC_N (SOIC-8) package, RoHS-compliant and tape-and-reel packaged per REEL7 standard. Thermal resistance θJA = 158°C/W.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT A | Amplifier A output; drives loads down to 600 Ω while swinging to within 8 mV of V–. |
| 2 | –IN A | Inverting input A; accepts signals from 0 V to 4 V (V+ −1 V) with 93 dB CMRR. |
| 3 | +IN A | Non-inverting input A; same common-mode range as –IN A; enables true single-supply differential sensing. |
| 4 | V– | Negative supply rail; reference for both inputs and output; output swings to within 8 mV of this pin at 5 V. |
| 5 | +IN B | Non-inverting input B; independent channel; identical specs and range to +IN A. |
| 6 | –IN B | Inverting input B; fully isolated from Channel A; supports dual-sensor or signal+reference architectures. |
| 7 | OUT B | Amplifier B output; electrically identical to OUT A; enables dual-channel instrumentation without cross-talk. |

| No phase reversal | Guaranteed when inputs remain within supply rails-eliminates latch-up risk in overvoltage sensor transients. |
| Low 0.1–10 Hz noise | 120 nV p-p-enables stable DC-coupled amplification of thermocouple and RTD outputs without AC coupling. |
| Extended input common-mode range | Includes V– and extends to V+ −1 V-supports direct connection to grounded shunt resistors or bridge midpoints. |
| Unity-gain stability | Stable at AV = 1 with 57° phase margin @ 5 V-allows use in voltage followers for sensor buffering without compensation. |

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 | Chopper-stabilized architecture; 0.1 μV/°C drift, but 10× higher 1/f noise (1.1 μV p-p) and 1.5 MHz GBW. | Better drift spec, but unsuitable for >100 kHz sensor signals due to chopping artifacts and limited bandwidth. | Select AD8628ARZ only when ultra-low drift dominates over noise bandwidth and signal fidelity requirements. |
| OPA2188AIDR | Zero-drift auto-zero topology; 0.003 μV/°C drift, 8.8 nV/√Hz noise, 2 MHz GBW, rail-to-rail I/O. | Superior drift cancellation but higher broadband noise degrades SNR in low-level strain gage applications. | Choose OPA2188AIDR for DC-critical applications like precision references where 1/f noise matters more than white noise. |
Compared with AD8628ARZ and OPA2188AIDR, OP213FSZ-REEL7 offers the optimal balance of ultra-low white noise (4.7 nV/√Hz), moderate drift (0.2 μV/°C), and wide bandwidth (3.4 MHz)-making it uniquely suited for high-fidelity, wideband sensor signal chains where both noise floor and thermal stability are critical.

FAQ
What is the maximum supply voltage for OP213FSZ-REEL7?
The OP213FSZ-REEL7 supports a single-supply range of 4 V to 36 V or dual-supply operation from ±4 V to ±18 V. Absolute maximum ratings specify ±18 V supply voltage-exceeding this risks permanent damage. Operation at 36 V single supply is permitted and validated per datasheet Table 3, with thermal derating required above 70°C ambient.
Does OP213FSZ-REEL7 require external compensation for unity-gain stability?
No, OP213FSZ-REEL7 is internally compensated for unity-gain stability. It achieves 57° phase margin at 5 V supply and 72° at ±15 V, as confirmed in Figures 18 and 21 of the Rev. F datasheet. No external capacitors or resistors are needed for stable operation with gain ≥1, simplifying layout in space-constrained sensor modules.
Can OP213FSZ-REEL7 drive a 600 Ω load while maintaining rail-to-rail output swing?
Yes-OP213FSZ-REEL7 is specified to deliver 3.9 V output swing into 600 Ω at 5 V supply (VOL = 8 mV, VOH = 3.9 V), per Table 2. This meets the requirement for driving legacy 600 Ω ADC inputs or transmission lines without external buffers, preserving signal integrity and minimizing component count.
Is OP213FSZ-REEL7 pin-compatible with other OPx13 family members?
OP213FSZ-REEL7 shares the same 8-lead SOIC_N pinout as OP113 and OP413 dual variants (Figures 1 and 2), but differs from OP413's 16-lead SOIC_W. Pin compatibility exists only between OP113, OP213, and OP413 dual-channel versions in SOIC-8 packages-enabling drop-in replacement where dual-channel count matches system requirements.
What is the guaranteed input offset voltage specification for OP213FSZ-REEL7 over temperature?
For the F-grade OP213FSZ-REEL7, input offset voltage is guaranteed ≤325 μV over –40°C to +85°C (Table 1), with typical value of 150 μV at 25°C. This specification is production-tested and assured across all units-not just typical characterization-ensuring consistent performance in production calibration routines.
