Product details
Overview
AD711JRZ-REEL from Analog Devices is a precision, high-speed BiFET operational amplifier in an 8-pin SOIC package, delivering 3 MHz unity-gain bandwidth, 16 V/µs slew rate, and 1.0 µs settling time to ±0.01%. It features 0.25 mV max input offset voltage (C-grade), 25 pA max input bias current, and 4 µVP-P low-frequency noise (0.1–10 Hz), making it ideal for 12-bit DAC/ADC buffering and photodiode preamplification.
For engineers reviewing the AD711JRZ-REEL datasheet, AD711JRZ-REEL pinout, AD711JRZ-REEL application, or AD711JRZ-REEL equivalent, key selection criteria include guaranteed settling time performance, J-grade temperature range (0°C to +70°C), SOIC tape-and-reel packaging, and BiFET input stage compatibility with high-impedance signal sources.
Technical Context
The AD711JRZ-REEL employs a laser-trimmed BiFET input stage enabling ultra-low input bias current (25 pA max) and stable dc performance across temperature. Its architecture balances ac speed and stability: 3 MHz bandwidth and 16 V/µs slew rate are optimized to achieve sub-microsecond settling without sacrificing phase margin when driving 100 pF loads in unity-gain configurations.
It supports standard op amp feedback topologies including inverting, noninverting, and integrator configurations. Input common-mode range extends to ±11.5 V with ±15 V supplies, and output swing reaches ±13 V into 2 kΩ, ensuring robust operation in precision analog signal chains requiring rail-to-rail compatible headroom.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TL081CP | Higher input offset voltage (6 mV max), slower slew rate (13 V/µs), no guaranteed settling time spec. | Lower-cost general-purpose use; unsuitable for 12-bit DAC buffering where 1 µs settling is required. | Select TL081CP only for non-critical DC-coupled amplifiers where cost dominates performance requirements. |
| LF356N | Wider bandwidth (5 MHz), but higher input bias current (30 pA typ), no 100% slew rate test, no 0.01% settling guarantee. | Better high-frequency response but less predictable settling behavior; not validated for precision DAC timing-critical roles. | Choose LF356N for bandwidth-sensitive active filters, but verify settling empirically before using in DAC/ADC interfaces. |
Compared with TL081CP and LF356N, AD711JRZ-REEL uniquely combines guaranteed 1.0 µs ±0.01% settling, 25 pA input bias current, and J-grade temperature validation-making it the only option qualified for production 12-bit data conversion systems requiring both speed and dc precision.

FAQ
What is the operating temperature range for AD711JRZ-REEL?
The AD711JRZ-REEL is rated for the commercial temperature range of 0°C to +70°C, as specified in the Analog Devices ordering guide. This grade (J) is distinct from industrial (A/B/C) and military (S/T) variants. All electrical specifications-including slew rate, settling time, and offset voltage-are guaranteed across this full range, making AD711JRZ-REEL suitable for office, lab, and non-extreme industrial environments where ambient conditions remain within these limits.
Does AD711JRZ-REEL require external offset nulling in all applications?
AD711JRZ-REEL does not require external offset nulling for most applications, as its 2 mV max input offset voltage meets typical 12-bit system error budgets. However, Pin 1 and Pin 5 are provided for optional nulling via a 10 kΩ potentiometer when sub-millivolt dc accuracy is mandatory-such as in precision integrators or zero-drift sensor interfaces. The nulling network must be implemented per the AD711 datasheet Figure 21, and unused pins should remain unconnected if nulling is omitted.
Can AD711JRZ-REEL drive a 1000 pF capacitive load stably?
Yes, AD711JRZ-REEL can drive a 1000 pF capacitive load stably in unity-gain configuration when used with proper layout and decoupling. The datasheet confirms stable operation with 100 pF loads; for larger capacitances, a 100 Ω isolation resistor in series with the output (as shown in Figure 13) is recommended to maintain phase margin. Without isolation, instability may occur above ~200 pF. Always verify stability with actual load and board parasitics using step-response testing.
Is AD711JRZ-REEL pin-compatible with other SOIC op amps like OP27 or AD822?
No, AD711JRZ-REEL is not pin-compatible with OP27 or AD822. While all are 8-pin SOIC op amps, AD711JRZ-REEL follows the standard dual-supply op amp pinout (Pin 2: –IN, Pin 3: +IN, Pin 4: –VS, Pin 7: +VS, Pin 6: OUT), whereas OP27 uses different pin assignments (e.g., Pin 1: offset null, Pin 5: offset null, Pin 6: OUT), and AD822 is a dual op amp with distinct pin mapping. Direct replacement requires PCB redesign; always consult each device's connection diagram before substitution.
What is the maximum supply voltage rating for AD711JRZ-REEL?
The absolute maximum supply voltage for AD711JRZ-REEL is ±18 V, as stated in the Absolute Maximum Ratings table. Operation is specified over ±4.5 V to ±18 V, with optimal performance achieved at ±15 V. Exceeding ±18 V risks permanent damage. Quiescent current increases linearly with supply voltage (2.5–2.8 mA at ±15 V), so thermal design must account for worst-case dissipation-especially in SOIC packages with qJA = 160°C/W.
