Analog Devices Inc. OP213ESZ-REEL7

Overview

OP213ESZ-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, RTD, and thermocouple amplification with internal calibration systems.

For engineers reviewing the OP213ESZ-REEL7 datasheet, OP213ESZ-REEL7 pinout, OP213ESZ-REEL7 application, or OP213ESZ-REEL7 equivalent, this page provides verified technical context, real-world use cases, pin-level design meaning, and validated alternative options for low-noise, rail-to-rail output, single-supply op amp selection in 5 V and ±15 V systems.

Technical Context

The OP213ESZ-REEL7 implements a patented bipolar-CMOS hybrid output stage that enables true zero-volt output swing to within 8 mV of ground (at 5 V supply, RL = 600 Ω) while maintaining >100 dB CMRR over 0–4 V input common-mode range. Its input stage supports rail-to-rail common-mode operation down to the negative supply and up to 1 V below the positive rail.

It features unity-gain stability, no phase reversal under normal operating conditions, and guaranteed performance across –40°C to +85°C. Slew rate exceeds 0.6 V/μs (typ. 0.9 V/μs), and large-signal voltage gain remains ≥2 V/μV into 600 Ω loads - critical for driving ADC front-ends and sigma-delta converter buffers without gain compression.

Key Specifications

Manufacturer

Analog Devices is a global leader in high-performance analog, mixed-signal, and digital signal processing semiconductors, founded in 1965 and headquartered in Wilmington, MA.

The OPx13 family - including OP213ESZ-REEL7 - was designed specifically for processor-based systems with internal calibration, where low noise and minimal thermal drift are critical to preserving analog signal integrity without hardware recalibration.

FAQ

What is the maximum supply voltage for OP213ESZ-REEL7?

The absolute maximum supply voltage for OP213ESZ-REEL7 is ±18 V. Operating within the recommended range of ±15 V or single 5 V ensures guaranteed performance across –40°C to +85°C. Exceeding ±18 V risks permanent damage, as specified in Table 3 of the Rev. F datasheet.

Does OP213ESZ-REEL7 support rail-to-rail input?

OP213ESZ-REEL7 supports rail-to-rail input common-mode range down to the negative supply (V–) and up to 1 V below the positive supply (V+) across its full supply range. At 5 V operation, this means 0 V to 4 V input range - confirmed in Table 2 under "Input Voltage Range" and General Description.

Can OP213ESZ-REEL7 drive a 600 Ω load effectively?

Yes - OP213ESZ-REEL7 is fully specified into 600 Ω loads. Output voltage swing is guaranteed to 3.9 V (high) and 8 mV (low) at 5 V supply and –40°C to +85°C, with short-circuit current of ±30 mA. This makes it suitable for driving legacy ADC inputs and standard test equipment interfaces.

Is OP213ESZ-REEL7 pin-compatible with other OPx13 family members?

OP213ESZ-REEL7 shares the same 8-lead SOIC_N pinout as OP113 and OP413 variants in dual-channel configuration (Figure 2). However, OP113 is single-channel and OP413 is quad-channel - so physical pin compatibility exists only between OP213 and OP213 variants, not across channel counts.

What is the typical slew rate of OP213ESZ-REEL7 at 5 V supply?

The typical slew rate of OP213ESZ-REEL7 at 5 V supply is 0.9 V/μs (min 0.6 V/μs), as documented in Table 2 under "Slew Rate" with RL = 2 kΩ. This enables clean step response for 10 V p-p signals up to ~150 kHz without significant distortion - critical for fast strain transient capture.
