Operating from a single 4.5 V to 12 V supply or split supplies, it fits into 5 V and ±5 V systems without extra regulation. The 8-LFCSP (3x3) package with exposed pad provides a compact footprint and thermal path for dense layouts. The 410 MHz -3 dB bandwidth ensures the amplifier maintains flat gain up to several hundred megahertz, critical for preserving the harmonic content of high-speed signals like those from a 14-bit, 250 MSPS ADC. The 800 V/µs slew rate means the output can swing 4 V in 5 ns, so large-signal transients (e.g., pulse edges in radar or LIDAR) are reproduced without slew-induced distortion. Together, these specs keep the amplifier from becoming the bottleneck in a high-dynamic-range receiver or a wideband data-acquisition channel. With a supply span from 4.5 V to 12 V, the AD8139ACPZ-R2 can be powered from a single 5 V rail (common in many ADC driver circuits) or from ±5 V supplies for bipolar signal handling. The 100 mA output current per channel provides enough drive to charge the sampling capacitor of a high-speed ADC or to drive a 50 Ω terminated line. The 24.5 mA supply current is a reasonable quiescent draw for this performance class — budget the thermal dissipation in the 3 mm × 3 mm LFCSP if the ambient runs near 125°C. The wide temperature range also covers outdoor telecom cabinets and engine-bay electronics. The 150 µV input offset voltage and 2.25 µA input bias current are stable across temperature, so DC accuracy is maintained in precision measurement paths. ## Lifecycle and sourcing It is ROHS3 compliant. For new designs, this part can be qualified without planning for a last-time buy.","metaTitle":"AD8139ACPZ-R2 Differential Op-Amp, 410 MHz, 800 V/µs","metaDescription":"ADI AD8139ACPZ-R2 differential amplifier: 410 MHz -3 dB bandwidth, 800 V/µs slew rate, rail-to-rail output, 4.5–12 V supply, -40°C to 125°C.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Logic ICs"],"specifications":{"Package":"Tape & Reel (TR); Cut Tape (CT)","Slew Rate":"800V/µs","Output Type":"Differential, Rail-to-Rail","Mounting Type":"Surface Mount","-3db Bandwidth":"410 MHz","Amplifier Type":"Differential","Package / Case":"8-WFDFN Exposed Pad, CSP","lifecycle_stage":"eol_hot","Current - Supply":"24.5mA","Number of Circuits":"1","Current - Input Bias":"2.25 µA","Operating Temperature":"-40°C ~ 125°C","Voltage - Input Offset":"150 µV","Supplier Device Package":"8-LFCSP (3x3)","Current - Output / Channel":"100 mA","Voltage - Supply Span (Max)":"12 V","Voltage - Supply Span (Min)":"4.5 V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$11.89","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$11.89000","currency":"USD"},{"qty":10,"price":"$10.92500","currency":"USD"},{"qty":25,"price":"$10.47160","currency":"USD"},{"qty":100,"price":"$9.22650","currency":"USD"},{"qty":250,"price":"$8.77360","currency":"USD"},{"qty":500,"price":"$8.20758","currency":"USD"}]},"links":{"datasheetUrl":"https://www.analog.com/media/en/technical-documentation/data-sheets/AD8139.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is AD8139ACPZ-R2 obsolete?","answer":"No. It is suitable for new designs."},{"question":"What is the AD8139ACPZ-R2 bandwidth?","answer":"The -3 dB bandwidth is 410 MHz, making it suitable for driving ADCs up to several hundred MSPS or conditioning wideband analog signals."},{"question":"How does AD8139ACPZ-R2 compare to AD8138?","answer":"The AD8139ACPZ-R2 offers a higher 410 MHz bandwidth versus the AD8138's typical 320 MHz, and a faster 800 V/µs slew rate compared to the AD8138's 350 V/µs.
