Analog Devices Inc. OP200GSZ

Overview

OP200GSZ from Analog Devices is a dual, low-offset, low-power precision operational amplifier in a 16-lead SOIC_W package. It delivers 75 μV max input offset voltage (at 25°C), 0.5 μV/°C max drift over −40°C to +85°C, 725 μA max supply current per amplifier, 5000 V/mV min open-loop gain, and stable operation with up to 10 nF capacitive loads - ideal for dual-channel precision signal conditioning in space-constrained industrial sensor interfaces.

For engineers reviewing the OP200GSZ datasheet, OP200GSZ pinout, OP200GSZ application, or OP200GSZ equivalent, this page provides verified technical context, military-grade temperature performance data, SOIC_W package layout details, real-world instrumentation amplifier and voltage reference use cases, and two validated alternative parts with documented functional trade-offs.

Technical Context

The OP200GSZ integrates two matched precision op amps on a single die using Zener zap trimming to achieve sub-75 μV offset without external nulling. Its architecture supports unity-gain stability while driving heavy capacitive loads - confirmed by 10 nF no-oscillation testing and <0.5 μV/°C drift across its full −40°C to +85°C operating range.

Each amplifier features 125 GΩ common-mode input resistance, 11 nV/√Hz voltage noise at 1 kHz, and >110 dB CMRR at ±12 V common-mode voltage - enabling high-accuracy differential sensing and low-drift reference buffering where input bias current (<2 nA) and long-term stability (<0.1 μV/month) are critical.

Key Specifications

FAQ

What is the maximum operating temperature range for OP200GSZ?

The OP200GSZ is rated for −40°C to +85°C operation, as confirmed in the Ordering Guide and Table 4 of the Rev. G datasheet. This industrial temperature range is distinct from the −55°C to +125°C rating of the OP200AZ variant and applies specifically to the GSZ suffix part number.

Does OP200GSZ require external offset nulling components?

No, OP200GSZ does not require external offset nulling components. Its input offset voltage is trimmed using on-chip Zener zap technology, achieving ≤200 μV max at 25°C without user adjustment - a key feature highlighted in the General Description section of the datasheet.

Can OP200GSZ drive a 10 kΩ load with full output swing?

Yes, OP200GSZ delivers ±12 V output swing into a 10 kΩ load at ±15 V supplies, as specified in Table 3 under Output Voltage Swing. This performance holds across its full −40°C to +85°C operating range and enables direct interfacing with standard ADC inputs and analog multiplexers.

What is the capacitive load limit for stable operation of OP200GSZ?

OP200GSZ is stable with up to 10 nF capacitive loads, as verified in Table 3 (Capacitive Load Stability) and Figure 24 (Overshoot vs. Capacitive Load). This allows direct connection to anti-aliasing filters or long PCB traces without external isolation resistors or compensation networks.

Is OP200GSZ RoHS compliant?

Yes, OP200GSZ is RoHS compliant, as explicitly stated in the Ordering Guide footnote: "The OP200GPZ, OP200GSZ, and OP200GSZ-REEL are RoHS Compliant Parts." This applies to both tube and reel packaging formats.
