Product details
Overview
AD713JNZ from Analog Devices is a precision quad BiFET operational amplifier optimized for high-speed, low-distortion signal conditioning in 12- to 14-bit data acquisition systems. It delivers 20 V/μs slew rate, 4 MHz unity-gain bandwidth, 1.5 mV max input offset voltage, and 0.0003% THD - enabling use as quad output buffers for precision DACs and input buffers for ADCs.
For engineers reviewing the AD713JNZ datasheet, AD713JNZ pinout, AD713JNZ application, or AD713JNZ equivalent, key selection criteria include settling time to 0.01% (1.0–1.2 μs), input bias current (40–150 pA), matching of ac/dc characteristics across all four amplifiers, and guaranteed performance over 0°C to 70°C.
Technical Context
The AD713JNZ integrates four matched AD711 BiFET op amps on a single monolithic die, ensuring tight ac and dc parameter tracking between channels - critical for active filter topologies and multi-channel instrumentation. Its internally compensated single-pole response enables stable unity-gain operation without external compensation.
Designed for precision analog signal paths, it features JFET-input stages with 3 TΩ input impedance, laser-trimmed dc specifications (offset, drift, bias current), and low 1/f noise (2 μV p-p, 0.1–10 Hz). The architecture supports fast recovery from large-signal transients - essential when driving switched-capacitor ADC inputs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Offset Voltage | Max 1.5 mV at 25°C; ensures ≤1 LSB error in 12-bit systems with ±10 V full-scale range. |
| Slew Rate | Min 16 V/μs; supports clean 10 V step response within 1.2 μs to 0.01% accuracy. |
| Unity-Gain Bandwidth | Typ 4 MHz; enables stable gain-of-1 buffering up to audio and medium-speed DAQ frequencies. |
| Total Harmonic Distortion | 0.0003% at 1 kHz; preserves signal fidelity in audio and precision waveform reconstruction. |
| Input Bias Current | 40–150 pA at 25°C; minimizes voltage error across high-impedance sensor or photodiode sources. |
| Open-Loop Gain | Min 150 V/mV (106 dB); provides high loop gain for accurate closed-loop gain setting and linearity. |
| Settling Time (0.01%) | 1.0–1.2 μs for 10 V step; meets timing budget for 1 MSPS+ successive-approximation ADC drivers. |
Pinout & Package
AD713JNZ is supplied in a 14-lead PDIP (plastic dual in-line package) with standard quad op amp pinout. Pin 1 is OUTPUT A; pins 2 and 3 are –IN A and +IN A; pin 4 is +VS; pins 5–8 are OUTPUT B, –IN B, +IN B, and NC; pins 9–11 are OUTPUT C, –IN C, +IN C; pin 12 is –VS; pins 13–14 are OUTPUT D, –IN D, +IN D.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 5, 9, 13 | Output (A–D) | Low-impedance buffered voltage source; capable of ±13.9/–13.3 V swing into 2 kΩ load. |
| 2, 6, 10, 14 | Inverting Input (A–D) | High-impedance JFET node; accepts differential signals up to ±20 V; sensitive to PCB leakage. |
| 3, 7, 11, 12 | Non-inverting Input (A–D) | Matched to inverting input; used for unity-gain follower or high-Z sensor interface configurations. |
| 4 | Positive Supply (+VS) | Accepts ±4.5 V to ±18 V; requires local 0.1 μF ceramic + 1 μF electrolytic bypassing. |
| 12 | Negative Supply (–VS) | Shared rail for all four amplifiers; must be decoupled identically to +VS for PSRR >76 dB. |

Use Scenario: Implementing 4th-order low-pass Butterworth filter in 16-bit data acquisition system with microprocessor-controlled cutoff frequency. IC Role / Device Role / Timing Role: All four AD713JNZ amplifiers configured as integrators and summing nodes in state-variable topology; leverages channel-to-channel matching for Q and fc stability. Use Value: Enables <±0.1% filter gain flatness and <0.05° phase error across 0–10 kHz due to <0.7 mV inter-amplifier offset matching. |
Use Scenario: Driving 14-bit multiplying DAC (e.g., AD7545) in bipolar, four-quadrant mode for programmable gain amplifier. IC Role / Device Role / Timing Role: Quad buffer isolating DAC output from varying load; each amplifier handles one quadrant or gain stage in cascaded configuration. Use Value: Achieves true 14-bit monotonicity by suppressing DAC output resistance-induced nonlinearity via <1.5 mV offset and <100 pA bias current. |
| ADC Input Driver | Photodiode Preamp |
|
Use Scenario: Buffering analog input of 12-bit SAR ADC (e.g., AD574A) in automated test equipment with 100 kSPS sampling. IC Role / Device Role / Timing Role: High-speed driver recovering from 2 mA transient sink/source currents induced by internal ADC sampling switch. Use Value: Recovers to 0.01% in <200 ns (per Figure 39), preventing conversion errors during successive-approximation cycles. |
Use Scenario: Transimpedance amplification of low-light photodiode signal in spectroscopy instrument requiring sub-pA dark current sensitivity. IC Role / Device Role / Timing Role: First-stage JFET-input amplifier converting photocurrent to voltage; operates at virtual ground with feedback resistor ≥1 GΩ.

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad precision op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OP400GPZ | Lower slew rate (0.15 V/μs), higher offset (250 μV), but lower input bias current (0.3 pA) and wider temp range (−40°C to +85°C). | Better for ultra-low bias current applications (e.g., picoampere electrometer), unsuitable for >10 kHz settling-critical DAC buffering. | Select OP400GPZ only when femtoampere-level input current dominates over speed and offset requirements. |
| TL074CN | Higher input bias current (30 nA), higher THD (0.005%), no guaranteed slew rate spec, but lower cost and widely available in PDIP. | Acceptable for non-critical audio or general-purpose filtering where 12-bit accuracy is sufficient. | Choose TL074CN only for cost-sensitive, non-precision applications; not suitable for 14-bit DAC/ADC interfaces. |
Compared with OP400GPZ and TL074CN, AD713JNZ uniquely balances 16 V/μs slew rate, 1.5 mV offset, and 40 pA bias current - making it the only option among the three qualified for simultaneous high-speed, high-resolution, and low-noise signal conditioning.

FAQ
What is the operating temperature range of the AD713JNZ?
The AD713JNZ is rated for the commercial temperature range of 0°C to +70°C. This is explicitly defined in the datasheet's Product Highlights and Absolute Maximum Ratings sections. The 'J' suffix denotes this grade, distinguishing it from the industrial-grade AD713A (−40°C to +85°C). Operation outside 0°C–70°C may result in parametric shift beyond guaranteed limits, and the AD713JNZ is not characterized for reliability or functionality beyond this range.
Does the AD713JNZ require external compensation capacitors?
No, the AD713JNZ is internally compensated for stable unity-gain operation. The General Description confirms it is "internally compensated for stable operation at unity gain," and the Theory of Operation section makes no mention of external compensation networks. Adding external capacitors may degrade bandwidth and settling performance. The device achieves 4 MHz unity-gain bandwidth and 1.2 μs 0.01% settling without any external components.
Can the AD713JNZ drive heavy capacitive loads directly?
The AD713JNZ is not optimized for direct heavy capacitive loading; driving >100 pF without isolation risks instability. Figure 40 in the datasheet recommends a 100 Ω series isolation resistor to stabilize operation with loads up to 1500 pF. Without this resistor, phase margin erodes due to pole splitting, potentially causing ringing or oscillation. For robust 500 pF+ loads, the AD713JNZ must be used with the recommended RC isolation network shown in Figure 40.
How does the AD713JNZ compare to the single-channel AD711?
The AD713JNZ contains four fully matched AD711-grade amplifiers on one die, providing identical dc and ac specs per channel - including <0.7 mV inter-amplifier offset matching and <8 μV/°C drift tracking. While the AD711 offers identical per-amplifier performance, it lacks channel-to-channel correlation. The AD713JNZ's monolithic integration enables precise multi-channel functions like state-variable filters and quad DAC buffering that discrete AD711s cannot replicate without costly calibration.
Is the AD713JNZ pin-compatible with other quad op amps like the TL074?
No, the AD713JNZ is not pin-compatible with TL074 or LF347. Its 14-lead PDIP pinout places +VS on pin 4 and –VS on pin 12, whereas TL074 uses pin 4 for –VS and pin 11 for +VS. Swapping them causes immediate power rail reversal and device damage. The AD713JNZ pinout is unique to its BiFET architecture and must be laid out per Figure 1 in the datasheet; no drop-in replacement exists among standard quad op amps.
