Product details
Overview
AD706JRZ-REEL7 from Analog Devices is a dual, low-power, precision bipolar operational amplifier optimized for low-frequency signal conditioning in instrumentation and data acquisition systems. It delivers 100 µV max input offset voltage, 1.5 µV/°C max offset drift, <200 pA input bias current, 0.5 µV p-p 0.1 Hz–10 Hz voltage noise, and 750 µA total quiescent supply current per amplifier - enabling high-accuracy integrators and active filters in 12-/14-bit DAQ applications.
For engineers reviewing the AD706JRZ-REEL7 datasheet, AD706JRZ-REEL7 pinout, AD706JRZ-REEL7 application, or AD706JRZ-REEL7 equivalent, key selection criteria include its picoampere-level input bias current stability over temperature, JFET-like input impedance without chopper noise, unity-gain stability, and SOIC-8 packaging suitable for high-density analog PCB layouts.
Technical Context
The AD706JRZ-REEL7 employs superbeta bipolar input transistors to achieve room-temperature input bias currents comparable to JFET op amps (≤200 pA), while maintaining only ~5× increase at +125°C - unlike JFETs, which double every 10°C. Its internal compensation ensures stable unity-gain operation without external compensation components.
It features matched dual amplifiers with guaranteed common-mode rejection ≥106 dB, power supply rejection ≥106 dB, and crosstalk >150 dB at 10 Hz. The device operates from ±2 V to ±18 V supplies and supports rail-to-rail output swing of ±13 V into 10 kΩ loads, making it suitable for precision DC-coupled signal chains requiring long-term stability and low 1/f noise.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Offset Voltage | Max 100 µV - enables sub-12-bit error floor in precision DC amplification without trimming. |
| Offset Drift vs. Temp | Max 1.5 µV/°C - ensures <1 µV drift across 0°C to +70°C commercial range, critical for unattended instrumentation. |
| Input Bias Current | Max 200 pA at 25°C - eliminates need for input balancing resistors in high-Z sensor interfaces (e.g., pH electrodes, photodiode TIA). |
| Voltage Noise (0.1–10 Hz) | 0.5 µV p-p - supports ultra-low-noise integration in precision weighing and strain gauge bridges. |
| Supply Current (Total) | 750 µA - allows dual-channel precision amplification on battery-powered or thermally constrained boards. |
| Unity-Gain Bandwidth | 0.8 MHz - sufficient for anti-aliasing and low-pass filtering up to ~100 kHz with phase margin >60°. |
| CMRR / PSRR | ≥106 dB - rejects power supply ripple and common-mode interference in noisy industrial environments. |
Pinout & Package
AD706JRZ-REEL7 is housed in an 8-lead narrow-body SOIC package (JEDEC MS-012-AA, package option R-8), measuring 4.90 mm × 3.90 mm × 1.75 mm, with gull-wing leads and 1.27 mm pitch. Tape-and-reel packaging (7-inch reel, EIA-481A compliant) supports automated SMT assembly.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Output A | Amplifier 1 output - drives feedback networks or downstream stages; capable of ±13 V swing into 10 kΩ. |
| 2 | Inverting Input A (–IN A) | High-impedance differential input node for Amplifier 1; protected by back-to-back diodes (±0.7 V differential limit). |
| 3 | Non-Inverting Input A (+IN A) | High-impedance differential input node for Amplifier 1; supports common-mode voltages up to ±13.5 V. |
| 4 | V– | Negative supply rail connection - must be decoupled with 0.1 µF ceramic capacitor near pin. |
| 5 | Non-Inverting Input B (+IN B) | High-impedance differential input node for Amplifier 2; electrically isolated but thermally coupled to Amplifier 1. |
| 6 | Inverting Input B (–IN B) | High-impedance differential input node for Amplifier 2; matches bias current and offset specs of Pin 2. |
| 7 | Output B | Amplifier 2 output - independently usable; supports same load drive and noise performance as Pin 1. |
| 8 | V+ | Positive supply rail connection - requires local 0.1 µF ceramic decoupling for stability and PSRR optimization. |
Key Features
| Feature | Design Value |
|---|---|
| Dual picoampere input bias current | ≤200 pA max at 25°C with <5× increase to +125°C - enables stable high-Z transducer interfacing without drift-induced errors. |
| Low 0.1 Hz–10 Hz voltage noise | 0.5 µV p-p - minimizes baseline wander in precision integrators and DC-coupled medical/sensor front-ends. |
| Matched dual amplifier pair | Offset voltage match ≤150 µV, input bias current match ≤300 pA - supports accurate two-op-amp instrumentation amplifier topologies (e.g., Figure 6). |
| Internal unity-gain compensation | No external compensation required - simplifies layout and guarantees stability in follower, inverter, and filter configurations. |
| Wide supply range | ±2 V to ±18 V operation - accommodates legacy ±15 V rails and modern low-voltage ±2.5 V/±3.3 V systems with headroom. |

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 |
|---|---|---|---|
| OP2177ARZ | Lower offset (25 µV max), higher supply current (1.2 mA total), wider bandwidth (1.3 MHz), no internal compensation. | Better for high-precision, higher-speed applications requiring external compensation; less suitable for simple unity-gain filters. | Select OP2177ARZ when sub-50 µV offset and >1 MHz GBW are mandatory; accept higher power and layout complexity. |
| LT1013DN8#PBF | Higher offset (250 µV max), lower supply current (350 µA total), slower slew rate (0.4 V/ms), PDIP-only packaging. | Cost-sensitive, lower-performance industrial designs where SOIC packaging and 100 µV offset are not required. | Select LT1013DN8#PBF for legacy through-hole designs or budget-limited applications accepting 2× offset and reduced noise performance. |
Compared with OP2177ARZ and LT1013DN8#PBF, AD706JRZ-REEL7 uniquely balances ultra-low input bias current (<200 pA), low 1/f noise (0.5 µV p-p), and unity-gain stability in SOIC-8 - making it optimal for high-Z, low-frequency, low-power precision analog circuits where chopper amplifiers introduce unacceptable noise.

FAQ
What is the operating temperature range for AD706JRZ-REEL7?
The AD706JRZ-REEL7 is rated for the commercial temperature range of 0°C to +70°C, as indicated by the "J" grade suffix in the part number. This specification is guaranteed per the AD706 datasheet Rev. G, with all electrical parameters tested across this range. The device uses the same SOIC-8 (R-8) package as the industrial-grade AD706ARZ-REEL7 but is characterized and screened only for the narrower commercial span.
Does AD706JRZ-REEL7 require external compensation for unity-gain stability?
No, AD706JRZ-REEL7 is internally compensated for unity-gain stability. The datasheet explicitly states "internally compensated for unity gain" and confirms stable operation in follower, inverter, and active filter configurations without added compensation components. This eliminates layout sensitivity and reduces bill-of-materials count in precision analog designs.
Can AD706JRZ-REEL7 replace JFET-input op amps like TL072 in high-impedance applications?
Yes - AD706JRZ-REEL7 provides JFET-level input bias current (<200 pA) with superior temperature stability (IB increases only ~5× to +125°C vs. 1000× for typical JFETs). Its bipolar superbeta input stage avoids JFET's exponential IB drift, making it more reliable in varying ambient conditions while retaining high input impedance (>300 GΩ common-mode).
What is the maximum capacitive load AD706JRZ-REEL7 can drive in unity-gain configuration?
AD706JRZ-REEL7 can safely drive up to 10,000 pF in unity-gain configuration, as specified in the "Capacitive Load Drive Capability" parameter (Gain = +1). This capability supports direct interfacing with ADC input capacitors, long cables, or multi-stage RC filters without oscillation - provided proper supply decoupling (0.1 µF ceramic per supply pin) is maintained.
Is AD706JRZ-REEL7 pin-compatible with other dual op amps in SOIC-8 packages?
AD706JRZ-REEL7 follows the standard dual op amp pinout (SOIC-8): 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+. It is pin-compatible with industry-standard dual op amps including OP2177ARZ, LT1013, and AD822ARZ, enabling drop-in replacement where bias current, noise, and drift requirements align.
