Product details
Overview
AD8067ARTZ-REEL7 from Analog Devices is a precision FET-input voltage feedback operational amplifier optimized for high-gain, wideband photodiode preamplification and composite amplifier stages. It delivers 54 MHz −3 dB bandwidth at G = +10, 640 V/µs slew rate, 6.6 nV/√Hz input voltage noise, 0.6 pA input bias current (typ), and rail-to-rail output swing on ±5 V to ±12 V supplies. Its laser-trimmed 1.0 mV max offset and −106 dB CMRR support precision DC-coupled signal conditioning in optical sensing systems.
For engineers reviewing the AD8067ARTZ-REEL7 datasheet, AD8067ARTZ-REEL7 pinout, AD8067ARTZ-REEL7 application, or AD8067ARTZ-REEL7 equivalent, key selection criteria include gain stability ≥8, FET-input low-noise performance, SOT-23-5 package thermal limitations, and compatibility with photodiode transimpedance configurations requiring sub-picoamp bias current and high dynamic range.
Technical Context
The AD8067ARTZ-REEL7 employs a dielectrically isolated eXtra Fast Complementary Bipolar (XFCB) process integrating N-channel JFET inputs with bipolar output stages. Its patented rail-to-rail output drives within 0.25 V of either rail while sourcing/sinking 30 mA, enabling full-scale signal utilization in single-supply photodiode interfaces.
Stable only for gains ≥8, it features no phase reversal across its common-mode input range (−5 V to +2 V on ±5 V, −12 V to +9 V on ±12 V), and uses internal cascoded JFET/NPN input switching to maintain functionality near VCC, avoiding saturation-induced errors in high-common-mode optical front-ends.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| −3 dB Bandwidth | 54 MHz at G = +10 (±5 V supply); enables >10 MHz small-signal amplification in precision photodiode preamps |
| Slew Rate | 640 V/µs (±5 V); supports fast transient response without distortion in pulse-amplification applications |
| Input Bias Current | 0.6 pA typical (25 °C); preserves photodiode linearity and dark-current accuracy in high-impedance transimpedance nodes |
| Input Voltage Noise | 6.6 nV/√Hz at 10 kHz; dominates total noise floor in low-source-impedance photodiode circuits |
| CMRR | −106 dB (±5 V); rejects power supply and ground bounce interference in mixed-signal PCB layouts |
| Supply Range | 5 V to 24 V (±2.5 V to ±12 V); supports dual-supply precision instrumentation and single-supply portable optical sensors |
| Quiescent Current | 6.5 mA typical; balances speed and power in battery-constrained or thermally constrained SOT-23-5 designs |
Pinout & Package
SOT-23-5 (RT-5) package: 2.9 mm × 1.6 mm × 1.15 mm body, 0.95 mm pitch, gull-wing leads, rated for −40°C to +85°C industrial operation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - VOUT | Amplifier output | Rail-to-rail capable; drives 1 kΩ load to ±4.92 V on ±5 V supply; requires external 0.1 µF bypass capacitor at pin |
| 2 - −IN | Inverting input | High-impedance FET node (1000 GΩ || 2.5 pF); connects to feedback network in transimpedance or inverting configurations |
| 3 - +IN | Noninverting input | High-impedance FET node (1000 GΩ || 1.5 pF); referenced to photodiode cathode or system ground in preamp topologies |
| 4 - −VS | Negative supply | Connects to ground (single-supply) or negative rail; must be decoupled with 10 µF + 0.1 µF capacitors per datasheet Figure 34 |
| 5 - +VS | Positive supply | Accepts 5–24 V; decoupling critical due to 6.5 mA quiescent current and high-frequency PSRR roll-off above 1 MHz |

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision high-speed op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AD8065ARTZ-REEL7 | Unity-gain stable; 145 MHz GBW; 160 V/µs slew rate; 0.8 pA input bias current | Supports G = +1 configurations unsuitable for AD8067ARTZ-REEL7; lower bandwidth limits large-signal fidelity | Select AD8065ARTZ-REEL7 when unity-gain buffering or lower-noise (<6.3 nV/√Hz) is required and bandwidth ≤145 MHz suffices |
| OPA656U | FET input; 230 MHz GBW; 250 V/µs slew rate; 1.3 pA input bias current; SOIC-8 package | Higher bandwidth but larger footprint and 2× quiescent current (12.5 mA); no rail-to-rail output | Choose OPA656U for >100 MHz closed-loop bandwidth needs where SOT-23-5 size and rail-to-rail swing are not mandatory |
Compared with AD8065ARTZ-REEL7 and OPA656U, AD8067ARTZ-REEL7 uniquely balances 54 MHz bandwidth, 0.6 pA bias current, rail-to-rail output, and SOT-23-5 size-making it optimal for space-constrained, high-impedance photodiode preamps requiring gain ≥8 and minimal thermal dissipation.

FAQ
What is the minimum stable gain for AD8067ARTZ-REEL7?
The AD8067ARTZ-REEL7 is stable only for noninverting gains ≥8. Attempting to use it at G = +1 or G = +2 causes peaking and potential oscillation due to insufficient phase margin. For unity-gain stable alternatives, consider the AD8065ARTZ-REEL7. The AD8067ARTZ-REEL7 datasheet explicitly states "Stable for gains ≥8" in its FEATURES section and provides compensation guidance for lower-gain use in the Applications section.
Does AD8067ARTZ-REEL7 support single-supply operation?
Yes, AD8067ARTZ-REEL7 supports true single-supply operation from +5 V to +24 V. Its input common-mode range includes ground (0 V) on +5 V supply, and its rail-to-rail output swings from 0.03 V to 4.94 V into 1 kΩ. This enables direct interfacing with sensors and ADCs in 5 V systems without level-shifting circuitry, as confirmed in Table 2 (SPECIFICATIONS FOR +5 V) and the GENERAL DESCRIPTION.
What is the maximum capacitive load AD8067ARTZ-REEL7 can drive?
The AD8067ARTZ-REEL7 can drive up to 120 pF with ≤30% overshoot under standard test conditions (G = +10, ±5 V). Driving larger loads requires series output resistance (e.g., 24.9 Ω snubber) or reduced gain to maintain stability, as shown in Figure 8 of the datasheet. Exceeding this limit risks ringing and settling degradation, especially in photodiode transimpedance applications where feedback capacitance interacts with load effects.
How does input bias current vary with temperature for AD8067ARTZ-REEL7?
AD8067ARTZ-REEL7 input bias current approximately doubles every 10°C rise in junction temperature, reaching 25 pA maximum over the full −40°C to +85°C industrial range. At +25°C, it is specified at 0.6 pA typical (5 pA max), and Figure 22 shows measured values rising from ~1 pA at −40°C to ~12 pA at +85°C on ±5 V supply. This behavior directly impacts long-term photodiode preamp accuracy and must be factored into worst-case design margins.
Is AD8067ARTZ-REEL7 pin-compatible with other SOT-23-5 op amps?
No documented pin-compatible replacements exist for AD8067ARTZ-REEL7 in the SOT-23-5 package with identical pinout (VOUT, −IN, +IN, −VS, +VS). While many SOT-23-5 op amps share this topology, the AD8067ARTZ-REEL7's gain stability requirement (≥8) and FET-input characteristics make functional substitution nontrivial. Always verify pin function mapping and stability conditions before substituting, as mismatched pinouts risk damage or malfunction.
