Dual voltage-feedback amplifier with 350 MHz bandwidth
The AD8039ARZ-REEL from Analog Devices is a dual voltage-feedback operational amplifier in an 8-SOIC surface-mount package. It delivers a -3 dB bandwidth of 350 MHz and a slew rate of 425 V/µs while drawing 1 mA per channel. The supply range spans 3 V to 12 V. Operating temperature covers -40°C to 85°C.
350 MHz bandwidth and 425 V/µs slew rate — what they mean for the signal path
The 350 MHz -3 dB bandwidth supports small-signal amplification up to the VHF range, enough for composite video, high-speed data acquisition front-ends, or IF amplifier stages. The 425 V/µs slew rate means the output can swing several volts in a few nanoseconds, preserving pulse fidelity in time-domain applications like laser diode drivers or fast comparator interfaces. At 1 mA per channel, the dual amplifier keeps the thermal load low on a densely populated board — a practical advantage when routing multiple channels in a compact 8-SOIC footprint.
Supply range and input offset — BOM-fit details
The 3 V to 12 V supply span lets the same part serve mixed-voltage designs without a dedicated regulator. Input offset voltage is 500 µV typical, and input bias current is 400 nA — both moderate figures that suit AC-coupled or moderate-precision DC paths but not precision instrumentation. The 8-SOIC package (0.154" body width) is a standard footprint shared across many op-amp families, so layout reuse is straightforward.
Lifecycle and sourcing — active, no LTB risk
The AD8039ARZ-REEL carries an Active product status per the manufacturer, with ROHS3 compliance. No last-time-buy or obsolescence notice is on record. For a BOM line that needs a dual wideband amplifier in an 8-SOIC, this part is a safe choice for both new designs and ongoing production. Sourcing is through independent distribution; current pricing and lead time are confirmed at quote time against an RFQ.
