Product details
Overview
OP400HSZ from Analog Devices is a quad low-offset, low-power operational amplifier in a 16-lead SOIC_W package, delivering 150 μV max input offset voltage, 725 μA max supply current per amplifier, and 11 nV/√Hz noise density at 1 kHz - designed for precision analog signal conditioning in industrial sensor interfaces and multichannel data acquisition systems.
For engineers reviewing the OP400HSZ datasheet, OP400HSZ pinout, OP400HSZ application, or OP400HSZ equivalent, this page provides verified technical context, military-grade temperature performance (−40°C to +85°C), confirmed pin-compatible SOIC_W footprint, and two validated alternative op amps with documented parameter trade-offs.
Technical Context
The OP400HSZ integrates four independent precision amplifiers on a single die, each featuring laser-trimmed input offset voltage and Zener-zap trimming to eliminate external nulling. Its architecture supports stable operation with ≥10 nF capacitive loads and maintains >115 dB CMR across its full operating temperature range.
It delivers 500 kHz gain-bandwidth product at unity gain, 0.15 V/μs slew rate, and open-loop gain exceeding 3000 V/mV into 10 kΩ - enabling high-accuracy closed-loop configurations without phase compensation in instrumentation-grade circuits.

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad precision operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OP400GSZ | Same SOIC_W package and electrical specs, but rated for 0°C to +70°C industrial range instead of −40°C to +85°C. | Suitable for commercial-grade embedded systems; not qualified for extended-temperature automotive or outdoor industrial use. | Select OP400GSZ only if ambient operating temperature remains above 0°C and cost sensitivity outweighs thermal margin requirements. |
| AD8628ARZ | Single-channel zero-drift op amp (0.1 μV/°C drift, 1.5 μV offset), not quad; SOIC-8 package; higher supply current (1.2 mA). | Requires four separate ICs and additional PCB area; superior drift performance but no channel matching or shared supply benefits. | Choose AD8628ARZ only when ultra-low drift dominates design priorities and board space/cost constraints permit discrete channel implementation. |
Compared with OP400GSZ, OP400HSZ adds extended temperature qualification without sacrificing offset, noise, or power - making it the sole choice for automotive cabin electronics and wide-range industrial control. Versus AD8628ARZ, OP400HSZ trades minor drift degradation for integrated quad functionality, lower total supply current, and inherent channel-to-channel matching.

FAQ
What is the maximum capacitive load the OP400HSZ can drive without oscillation?
The OP400HSZ is specified to remain stable with up to 10 nF capacitive load at unity gain, as confirmed in Table 1 and Figure 22 of the Rev. I datasheet. This capability allows direct interfacing with ADC input filters, long coaxial cables, or piezoelectric sensor outputs without external isolation resistors - a key advantage over many general-purpose op amps that require series-R compensation beyond 100 pF.
Does the OP400HSZ require external offset nulling circuitry?
No, the OP400HSZ does not require external offset nulling. Its input offset voltage is trimmed using on-chip Zener zap technology, guaranteeing ≤150 μV maximum at +25°C and ≤270 μV across −40°C to +85°C. This eliminates the need for potentiometers, trim pads, or calibration routines in production systems - reducing bill-of-materials cost and improving long-term reliability.
What is the operating temperature range for the OP400HSZ?
The OP400HSZ is rated for −40°C to +85°C operation, as explicitly stated in the Ordering Guide on page 15 of the Rev. I datasheet. This extended industrial temperature range qualifies it for use in automotive cabin electronics, outdoor industrial controllers, and avionics subsystems where ambient conditions exceed commercial-grade limits.
How does the supply current of the OP400HSZ compare to legacy precision op amps?
The OP400HSZ draws ≤725 μA per amplifier (≤2.9 mA total for all four), which is less than the typical supply current of a single OP07 (≈3.5 mA). This enables four-channel precision amplification within tighter power budgets - critical for battery-powered instrumentation, portable medical devices, and thermally constrained enclosures where heat dissipation must be minimized.
Is the OP400HSZ pin-compatible with other OP400 variants in SOIC_W packages?
Yes, the OP400HSZ uses the standard 16-lead SOIC_W (RW-16) footprint defined in Figure 37 and is fully pin-compatible with OP400GSZ, OP400GS, and OP400GBC-based modules. The pinout matches the industry-standard quad op amp configuration with no null terminals - allowing direct PCB replacement without layout modification when upgrading from commercial to extended-temperature grade.
