Product details
Overview
AD8627AKSZ-REEL from Analog Devices is a precision single-channel JFET-input operational amplifier in a 5-lead SC70 package, featuring 1 pA max input bias current, 5 MHz gain bandwidth, rail-to-rail output swing, and operation from 5 V to 26 V single supply or ±2.5 V to ±13 V dual supply. It delivers 500 µV max offset voltage and 630 µA typical supply current, enabling high-accuracy photodiode transimpedance amplification and low-power sensor signal conditioning.
For engineers reviewing the AD8627AKSZ-REEL datasheet, AD8627AKSZ-REEL pinout, AD8627AKSZ-REEL application, or AD8627AKSZ-REEL equivalent, key selection criteria include ultra-low input bias current for high-impedance sources, rail-to-rail output capability in single-supply systems, guaranteed industrial temperature range (−40°C to +85°C), and SC70 footprint compatibility with space-constrained PCB layouts.
Technical Context
The AD8627AKSZ-REEL uses an n-channel JFET input stage to achieve true single-supply operation with input common-mode voltage extending 0.2 V below V– and up to 2 V below V+, and a bipolar rail-to-rail output stage delivering <5 mV dropout at 2 mA load. Its unity-gain stable architecture supports capacitive loads >500 pF without oscillation.
It exhibits no phase reversal under overdrive conditions near the positive rail, maintains 104 dB PSRR and 87 dB CMRR at 25°C, and achieves 17.5 nV/√Hz voltage noise density at 1 kHz-critical for precision DC-coupled and low-frequency AC applications such as photodiode preamplifiers and DAC output buffers.
Key Specifications

|---|---|
| Input Bias Current | 1 pA max at 25°C - enables accurate amplification of signals from high-impedance sources like photodiodes without significant current-induced error. |
| Offset Voltage | 500 µV max - ensures ≤0.01% full-scale error in 5 V-range precision instrumentation and 14-bit DAC buffering. |
| Gain Bandwidth Product | 5 MHz - supports stable closed-loop operation up to 100 kHz full-power bandwidth with 20 Vp-p signals at ±13 V supply. |
| Supply Current per Amplifier | 630 µA typ - allows battery-powered operation for >1 year in low-duty-cycle sensor nodes using coin-cell batteries. |
| Rail-to-Rail Output Swing | Within 5 mV of rails at 2 mA - maximizes dynamic range in single-supply systems, e.g., interfacing with 3.3 V or 5 V ADCs without level-shifting. |
| Input Voltage Range | 0 V to 3 V on 5 V supply - accommodates inputs extending below ground in line-powered instrumentation with negative reference rails. |

Pinout & Package
AD8627AKSZ-REEL is housed in a 5-lead SC70 (KS suffix) surface-mount package, measuring 2.0 mm × 1.25 mm × 0.9 mm, optimized for high-density PCB layouts and automated assembly.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT | Amplifier output terminal; drives loads up to ±10 mA with rail-to-rail swing and <5 mV saturation voltage at 2 mA. |
| 2 | V– | Negative supply pin; accepts 0 V (single-supply) or −2.5 V to −13 V (dual-supply); internal ESD protection to −0.3 V. |
| 3 | +IN | Noninverting input; high-impedance JFET node with 1 pA max bias current; requires guarding for picoamp-level signal integrity. |
| 4 | V+ | Positive supply pin; accepts 5 V to 26 V (single) or +2.5 V to +13 V (dual); decoupling capacitor required within 1 cm. |
| 5 | –IN | Inverting input; matched to +IN for low input offset; sensitive to layout parasitics-must be routed away from noisy traces. |
Key Features
| Feature | Design Value |
|---|---|
| No phase reversal | Guaranteed under input overdrive up to +VS + 300 mV - eliminates catastrophic output inversion in photodiode or sensor front-end circuits. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision JFET op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA141AIDBVR | Higher 10 MHz GBW, 20 fA IB, but 1.2 mA supply current - 2× higher quiescent power than AD8627AKSZ-REEL. | Better for wideband sensor interfaces requiring >100 kHz small-signal bandwidth; less suitable for battery-powered nodes. | Select OPA141AIDBVR when bandwidth >5 MHz is mandatory and power budget allows ≥1.2 mA per channel. |
| ADA4625-1ACPZ-R7 | Lower 2.9 nV/√Hz noise, 2.5 pA IB, but only available in 8-lead LFCSP - no SC70 option; requires different PCB footprint. | Superior for low-noise audio preamps or medical EEG front-ends where voltage noise dominates; not drop-in replaceable. | Choose ADA4625-1ACPZ-R7 when sub-3 nV/√Hz noise is critical and board redesign for LFCSP is acceptable. |
Compared with OPA141AIDBVR and ADA4625-1ACPZ-R7, AD8627AKSZ-REEL uniquely balances ultra-low input current (1 pA), SC70 footprint, and 630 µA supply current-making it optimal for space- and power-constrained precision analog front-ends where 5 MHz bandwidth suffices.

FAQ
What is the maximum input bias current specification for AD8627AKSZ-REEL over temperature?
The AD8627AKSZ-REEL has a maximum input bias current of 60 pA over the full industrial temperature range (−40°C to +85°C), with 1 pA typical at 25°C. This performance is enabled by its n-channel JFET input stage and is critical for maintaining accuracy in high-impedance photodiode and sensor interfaces where leakage currents directly impact output error. The AD8627AKSZ-REEL datasheet specifies this value in Table 1 under "Input Bias Current" with conditions "–40°C < TA < +85°C".
Does AD8627AKSZ-REEL support true rail-to-rail input operation?
No, AD8627AKSZ-REEL does not support rail-to-rail input operation. Its input common-mode voltage range extends from 0.2 V below V– to 2 V below V+ on a 5 V supply (i.e., 0 V to 3 V), meaning it cannot accept signals within 2 V of the positive rail without increased error or bandwidth loss. However, it does provide rail-to-rail output swing-within 5 mV of both rails at 2 mA load-making it ideal for single-supply buffering of DACs and ASICs. This behavior is documented in the General Description and Applications Information sections of the AD8627AKSZ-REEL datasheet.
Can AD8627AKSZ-REEL drive capacitive loads without instability?
Yes, AD8627AKSZ-REEL is specified to remain stable with capacitive loads exceeding 500 pF, as confirmed in the General Description and Typical Performance Characteristics (Figure 31–32). This capability eliminates the need for external isolation resistors or compensation networks when driving ADC input filters, long cables, or piezoelectric sensors. Stability is maintained due to its robust phase margin (>60°) and internal compensation, verified across supply voltages (5 V and ±13 V) and temperature (−40°C to +85°C). This makes AD8627AKSZ-REEL suitable for direct interface with high-capacitance nodes without design iteration.
What is the recommended power supply decoupling for AD8627AKSZ-REEL?
Analog Devices recommends a 0.1 µF ceramic capacitor placed as close as possible (<1 cm) to the V+ and V– pins of AD8627AKSZ-REEL, with short, low-inductance traces to the ground plane. For systems with noisy supplies, adding a 10 µF tantalum or ceramic bulk capacitor nearby improves PSRR above 100 kHz. These values are validated in the Applications Information section and reflected in evaluation board layouts (e.g., Figure 46). Proper decoupling ensures the AD8627AKSZ-REEL maintains its specified 104 dB PSRR and prevents oscillation under dynamic load conditions.
Is AD8627AKSZ-REEL pin-compatible with other members of the AD862x family?
No, AD8627AKSZ-REEL is not pin-compatible with AD8626 or AD8625. It uses a 5-lead SC70 package (KS suffix), whereas AD8626 is offered in 8-lead SOIC (R-8) or MSOP (RM), and AD8625 in 14-lead SOIC (R) or TSSOP (RU). Pin configurations differ significantly: AD8627AKSZ-REEL has dedicated OUT, V–, +IN, V+, and –IN pins in SC70 layout, while multi-channel variants integrate additional channels and require different routing. The AD8627AKSZ-REEL datasheet explicitly states "The AD8627 is available in both 5-lead SC70 and 8-lead SOIC surface-mount packages", confirming the SC70 variant's unique 5-pin mapping.
