Product details
Overview
OP200GPZ from Analog Devices is a dual, low-offset, low-power precision operational amplifier in an 8-lead PDIP package. It delivers 75 μV max input offset voltage, 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 11 nV/√Hz noise density at 1 kHz - enabling high-accuracy signal conditioning in space-constrained industrial sensor interfaces.
For engineers reviewing the OP200GPZ datasheet, OP200GPZ pinout, OP200GPZ application, or OP200GPZ equivalent, this page provides verified technical context, military-grade temperature performance boundaries, capacitive-load stability data (10 nF), dual-amplifier channel separation (123 dB), and RoHS-compliant sourcing guidance for legacy through-hole designs requiring long-term component continuity.
Technical Context
The OP200GPZ integrates two matched precision op amps on a single die with on-chip Zener zap trimming to achieve sub-75 μV offset without external nulling. Its architecture supports unity-gain stability while driving up to 10 nF capacitive loads - critical for driving ADC input filters or long cables without phase margin loss.
It operates from ±3 V to ±18 V supplies, maintains >115 dB CMRR and <1.8 μV/V PSRR across temperature, and achieves 0.1 Hz–10 Hz noise of 0.5 μV p-p - making it suitable for DC-coupled instrumentation where drift and low-frequency noise dominate error budgets.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Offset Voltage | 200 μV max - defines worst-case DC error in precision gain stages without trimming |
| Offset Voltage Drift | 0.5 μV/°C max - ensures ≤1.25 μV total drift over full −40°C to +85°C operating range |
| Supply Current per Amp | 725 μA max - enables dual-channel operation below 1.45 mA total, halving power vs. OP07 |
| Open-Loop Gain | 3000 V/mV min into 10 kΩ - guarantees ≥120 dB loop gain at unity gain, supporting stable 12-bit accuracy |
| Noise Density | 11 nV/√Hz at 1 kHz - half the voltage noise of competitive precision op amps, improving SNR in sensor front-ends |
| Capacitive Load Stability | 10 nF typical - eliminates need for isolation resistors when driving SAR ADC inputs or coaxial cables |
| CMRR | 115 dB min - rejects common-mode interference in noisy industrial environments (e.g., motor drives) |
Pinout & Package
OP200GPZ uses an 8-lead plastic dual in-line package (PDIP, P-Suffix, N-8) with standard industry pinout. Pin 1 = OUT A, Pin 2 = –IN A, Pin 3 = +IN A, Pin 4 = V–, Pin 5 = +IN B, Pin 6 = –IN B, Pin 7 = OUT B, Pin 8 = V+.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OUT A) | Amplifier A output | Drives external load; rail-to-rail swing limited to ±12 V (10 kΩ load) for predictable headroom |
| 2 (–IN A) | Inverting input A | Differential pair input node; 125 GΩ common-mode resistance minimizes leakage-induced offset |
| 3 (+IN A) | Non-inverting input A | High-impedance node; 10 MΩ differential resistance preserves source signal integrity |
| 4 (V–) | Negative supply rail | Reference for internal biasing; must be decoupled locally to suppress supply noise coupling |
| 5 (+IN B) | Non-inverting input B | Independent second channel input; identical specs to Channel A for matched dual functionality |
| 6 (–IN B) | Inverting input B | Enables differential sensing or independent signal path; no crosstalk impact beyond 123 dB channel separation |
| 7 (OUT B) | Amplifier B output | Electrically isolated output stage; supports simultaneous dual-sensor conditioning without shared loading |
| 8 (V+) | Positive supply rail | Accepts ±3 V to ±18 V; PSRR <1.8 μV/V ensures minimal supply ripple translation to output |
Key Features
| Feature | Design Value |
|---|---|
| Zener zap-trimmed offset | Eliminates need for external offset-null circuitry, reducing BOM count and PCB area in precision analog modules |
| Stable with 10 nF load | Permits direct connection to ADC input capacitors or long traces without destabilizing feedback networks |
| 0.5 μV/°C max drift | Meets military-grade thermal stability requirements for uncalibrated field-deployed instrumentation |
| 725 μA per amplifier | Enables dual-channel operation under 1.5 mA total - ideal for battery-powered portable test equipment |
| 123 dB channel separation | Prevents inter-channel signal coupling in dual-sensor systems (e.g., bridge-based strain gauge pairs) |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual precision op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OP27GPZ | Higher speed (8 MHz GBW), higher supply current (1.25 mA/amp), 25 μV offset - but only single-channel and not RoHS-compliant in PDIP | Preferred for bandwidth-critical applications (>100 kHz), unsuitable for dual-channel space-constrained layouts | Select OP27GPZ only if single-channel speed outweighs dual-channel integration and RoHS compliance needs. |
| AD8628ARZ | Zero-drift architecture, 1 μV offset, 0.002 μV/°C drift, but 1.2 mA/amp supply current and SOIC-only packaging | Better for ultra-low-drift DC applications; incompatible with through-hole PDIP assembly and legacy socketed designs | Choose AD8628ARZ when drift dominates error budget and reflow-compatible SOIC is acceptable. |
Compared with OP200GPZ, OP27GPZ trades dual-channel integration and RoHS compliance for bandwidth, while AD8628ARZ improves drift by 250× but doubles supply current and abandons through-hole support - making OP200GPZ the optimal choice for cost-sensitive, dual-channel, RoHS-compliant industrial DIP designs requiring proven military-temperature stability.

FAQ
What is the maximum operating temperature range for the OP200GPZ?
The OP200GPZ is specified for −40°C to +85°C operation, as confirmed in the Ordering Guide and Table 2 of the Rev. G datasheet. This commercial temperature grade distinguishes it from the OP200AZ (−55°C to +125°C) and aligns with industrial control and data acquisition system requirements where extended cold-start capability is not required.
Is the OP200GPZ RoHS compliant?
Yes, the OP200GPZ is explicitly designated RoHS compliant in the Ordering Guide footnote: "The OP200GPZ, OP200GSZ, and OP200GSZ-REEL are RoHS Compliant Parts." This applies to the 8-lead PDIP package (P-Suffix) and confirms lead-free finish and restricted substance compliance per EU Directive 2011/65/EU.
Does the OP200GPZ require external offset nulling components?
No, the OP200GPZ uses on-chip Zener zap trimming to achieve its 200 μV max input offset voltage, eliminating the need for external offset-null pins or potentiometers. This simplifies PCB layout and improves reliability in high-vibration environments where mechanical trimmers may drift.
Can the OP200GPZ drive a 10 kΩ load to ±12 V with ±15 V supplies?
Yes - the datasheet specifies ±12 V minimum output voltage swing into a 10 kΩ load at ±15 V supplies (Table 2). This 4 V headroom from each rail enables robust interfacing with 12-bit ADCs and analog switches without clipping during transient overloads.
What is the capacitive load limit for stable operation of the OP200GPZ?
The OP200GPZ is stable with up to 10 nF capacitive loads at unity gain, as verified in Table 3 and Figure 24. This allows direct connection to ADC input capacitors, coaxial cables, or piezoelectric sensor elements without added series resistance or compensation networks.
