Product details
Overview
AD8034ARZ-REEL from Analog Devices is a dual, FET-input, voltage-feedback operational amplifier optimized for high-speed, low-noise signal conditioning in instrumentation and active filtering. It delivers 80 MHz −3 dB bandwidth (G = +1), 80 V/μs slew rate (G = +2), 11 nV/√Hz input voltage noise at 100 kHz, rail-to-rail output swing, and operates from 5 V to 24 V single or split supplies.
For engineers reviewing the AD8034ARZ-REEL datasheet, AD8034ARZ-REEL pinout, AD8034ARZ-REEL application, or AD8034ARZ-REEL equivalent, this page provides verified circuit role, validated SOIC-8 package mapping, confirmed dual-channel FET op amp identity, exact DC and dynamic specifications per supply condition, and two rigorously validated alternative parts with documented technical and application differences.
Technical Context
The AD8034ARZ-REEL employs a proprietary XFCB process with N-channel JFET input stage and folded-cascade topology, enabling 1 pA typical input bias current and >90 dB CMRR/PSRR across frequency. Its bipolar-enhanced common-mode input range supports operation from 0 V to 2.0 V on +5 V supply and −12 V to +9 V on ±12 V supply without phase reversal.
The rail-to-rail common-emitter output stage drives up to 40 mA load current, sustains 35 pF capacitive load at G = +1 (30% overshoot), and achieves 95 ns settling time to 0.1% for 2 V step (G = +2) under ±5 V supply. Input overdrive recovery is 135 ns (±5 V) and 100 ns (±12 V).
Key Specifications
| Parameter | Value and Actual Design Meaning |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual FET-input op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA2350UA | Lower 38 MHz bandwidth, 22 V/μs slew rate; 0.45 mA/quiescent current; SC70-8 package only | Better suited for ultra-low-power battery sensors; insufficient for >5 MHz signal paths | Select when power budget <1 mA/channel is mandatory and bandwidth ≤3 MHz suffices |
| ADA4891-2ARZ | Higher 225 MHz bandwidth, 170 V/μs slew rate; 5.6 mA/quiescent current; SOIC-8 compatible | Optimized for video and composite signal routing; higher noise (7 nV/√Hz) limits precision use | Select when >100 MHz small-signal response is required and 11 nV/√Hz noise is non-critical |
Compared with OPA2350UA and ADA4891-2ARZ, AD8034ARZ-REEL uniquely balances 80 MHz bandwidth, 1 pA bias current, and 3.3 mA power in SOIC-8 - making it optimal for dual-channel instrumentation where precision, speed, and board space co-constrain selection.

FAQ
What is the operating temperature range for AD8034ARZ-REEL?
The AD8034ARZ-REEL is rated for industrial temperature operation from −40°C to +85°C, with all specifications guaranteed across this range under specified supply and load conditions. This rating applies to the SOIC-8 package variant and is validated per Analog Devices Rev. D datasheet Table 1–3 and Absolute Maximum Ratings section.
Does AD8034ARZ-REEL support single-supply operation?
Yes, AD8034ARZ-REEL supports true single-supply operation from 5 V to 24 V. Its input common-mode range extends to 0 V on +5 V supply, and its rail-to-rail output swings within 160 mV of both rails at 1 kΩ load - enabling direct interface with microcontrollers and ADCs without level-shifting circuitry.
What is the maximum capacitive load AD8034ARZ-REEL can drive stably?
AD8034ARZ-REEL is compensated to drive up to 35 pF at G = +1 with ≤30% overshoot (per Rev. D datasheet, Table 1–3 and Figure 23). For larger loads, a series snub resistor (e.g., 25 Ω) between output and capacitance restores stability, as demonstrated in Figure 12 and Theory of Operation section.
Is AD8034ARZ-REEL pin-compatible with other dual op amps in SOIC-8?
No documented pin-to-pin compatibility exists between AD8034ARZ-REEL and industry-standard dual op amps (e.g., LM358, TL072, OPA2340). Its pinout (VOUT1, –IN1, +IN1, –VS, +IN2, –IN2, VOUT2, +VS) is unique to the AD8033/AD8034 family and must be verified against Figure 3 of the datasheet for PCB layout.
What is the input offset voltage specification for AD8034ARZ-REEL?
AD8034ARZ-REEL has a typical input offset voltage of 1 mV and a maximum of 2 mV at TA = 25°C (±5 V supply), with worst-case 3.5 mV across −40°C to +85°C. Input offset voltage match between channels is 2.5 mV max, supporting precision differential signal processing.
