Product details
Overview
AD8039SRZ-EPR7 from Analog Devices is a dual, voltage-feedback operational amplifier optimized for high-speed, low-power applications. It delivers 350 MHz −3 dB bandwidth (G = +1), 425 V/μs slew rate, and 1.0 mA quiescent current per amplifier, operating across ±5 V or single 3 V to 12 V supplies. It serves as an ADC driver and buffer in battery-powered instrumentation and precision signal conditioning circuits.
For engineers reviewing the AD8039SRZ-EPR7 datasheet, AD8039SRZ-EPR7 pinout, AD8039SRZ-EPR7 application, or AD8039SRZ-EPR7 equivalent, key selection criteria include its extended temperature range (−55°C to +105°C), SOIC_N package compatibility, capacitive load drive capability up to 20 pF, and low-noise performance (8 nV/√Hz at 100 kHz).
Technical Context
The AD8039SRZ-EPR7 implements a voltage-feedback architecture with fully differential input stage and rail-to-rail output swing within 1 V of each supply rail. Its XFCB process enables simultaneous low noise (8 nV/√Hz, 600 fA/√Hz) and low quiescent current (1.0 mA/amplifier).
It supports gain stability from G = +1 to +10, maintains 0.1 dB flatness to 45 MHz at G = +2, and exhibits 18 ns settling time to 0.1% with 2 V step input. Input common-mode range extends to 1 V beyond either rail, and output crosstalk is −70 dB at 5 MHz.
Key Specifications
| Parameter | Value and Actual Design Meaning |

| −3 dB Bandwidth | 350 MHz at G = +1; enables wideband signal amplification without phase distortion in RF and video paths. |
| Slew Rate | 425 V/μs; supports fast transient response for pulse and digital signal conditioning. |
| Quiescent Current | 1.0 mA per amplifier; allows dual-channel high-speed operation in power-constrained systems like portable test gear. |
| Input Voltage Noise | 8 nV/√Hz at 100 kHz; preserves SNR in precision sensor front-ends and low-level analog acquisition. |
| Capacitive Load Drive | 20 pF at G = +2 with ≤30% overshoot; permits direct interface to ADC inputs and PCB traces without external isolation resistors. |

Pinout & Package
The AD8039SRZ-EPR7 is housed in an 8-lead SOIC_N (narrow-body) package compliant with JEDEC MS-012-AA, with 1.27 mm lead pitch and 5.00 mm × 4.00 mm body dimensions.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - VOUT1 | Output of Amplifier 1 | Provides buffered, high-slew-rate output; capable of driving 2 kΩ loads and up to 20 pF capacitance. |
| 2 - –IN1 | Inverting Input of Amplifier 1 | Differential input node with 10 MΩ resistance and 2 pF capacitance; sets gain when used with feedback network. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-speed, low-power op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AD8038ARZ | Single-channel version; identical bandwidth (350 MHz), slew rate (425 V/μs), and quiescent current (1.0 mA), but lacks second amplifier. | Used where space or cost constraints favor single-channel implementation; no dual-channel functionality. | Select AD8038ARZ when only one high-speed path is required and board area is constrained. |
| LMH6629MA/NOPB | Higher quiescent current (4.5 mA), wider bandwidth (1.5 GHz), and higher noise (2.9 nV/√Hz); not rated for extended temperature. | Targeted at commercial-grade, high-frequency test equipment where power budget allows. | Choose LMH6629MA/NOPB only if bandwidth >1 GHz is mandatory and −55°C to +105°C operation is unnecessary. |
Compared with AD8039SRZ-EPR7, AD8038ARZ offers identical per-channel performance in a smaller footprint but no dual-channel capability, while LMH6629MA/NOPB trades significant power increase and temperature limitation for extreme bandwidth - making AD8039SRZ-EPR7 optimal for dual-channel, extended-temperature, low-power systems.

FAQ
What is the maximum capacitive load the AD8039SRZ-EPR7 can drive stably?
The AD8039SRZ-EPR7 is specified to drive up to 20 pF capacitive load with ≤30% overshoot at G = +2. Driving larger loads requires a small series resistor (e.g., 10–50 Ω) at the output to maintain stability and prevent peaking. This capability makes AD8039SRZ-EPR7 suitable for direct connection to ADC inputs and PCB interconnects without additional compensation networks.
Does the AD8039SRZ-EPR7 support single-supply operation?
Yes, the AD8039SRZ-EPR7 operates from a single 3 V to 12 V supply. Its input common-mode range extends from 1.0 V to 4.0 V (at VS = 5 V), and output swings from 0.9 V to 4.1 V - enabling full-scale signal handling in 5 V systems. For 3 V operation, input and output ranges scale accordingly, preserving rail-to-rail usability.
What is the input bias current specification for the AD8039SRZ-EPR7 over temperature?
The AD8039SRZ-EPR7 has a maximum input bias current of 750 nA at TA = 25°C and up to 2.0 μA across the full operating range of −55°C to +105°C. This low, well-characterized bias current supports high-impedance sensor interfaces such as photodiode transimpedance stages without significant offset drift.
Is the AD8039SRZ-EPR7 pin-compatible with standard AD8039 variants?
Yes, the AD8039SRZ-EPR7 uses the same 8-lead SOIC_N (R-8) package and identical pinout as the commercial AD8039ARZ and AD8039AR. All share Pin 1 = VOUT1, Pin 2 = –IN1, Pin 3 = +IN1, Pin 4 = –VS, Pin 5 = +IN2, Pin 6 = –IN2, Pin 7 = VOUT2, Pin 8 = +VS - enabling drop-in replacement in existing layouts qualified for the AD8039 family.
What packaging and environmental qualifications apply to the AD8039SRZ-EPR7?
The AD8039SRZ-EPR7 is supplied in an 8-lead SOIC_N package (JEDEC MS-012-AA) and is qualified per AQEC standards for defense and aerospace use. It features controlled manufacturing baseline, single assembly/test site, extended temperature operation (−55°C to +105°C), and RoHS compliance (indicated by "Z" suffix). These attributes make AD8039SRZ-EPR7 suitable for mission-critical embedded systems.
