80 MHz bandwidth, 13 V/µs slew rate — the signal chain bottleneck
The ADA4841-1YRZ-R7 is a single-channel voltage feedback amplifier from Analog Devices, with an 80 MHz -3dB bandwidth and a 13 V/µs slew rate. This combination sets the large-signal frequency ceiling: for a 2 Vpp output, the full-power bandwidth is about 1 MHz, so the part is suited for ADC drivers, video buffers, or high-speed filter stages where the signal swing stays within the rail-to-rail output range. The 40 µV typical input offset voltage and 3 µA input bias current keep DC errors low enough for 12-bit acquisition systems without external trimming, though the bias current is higher than a JFET input stage — plan the source impedance accordingly.
Supply rails and power budget — 2.7 V to 12 V, 1.5 mA per channel
Operating from a single supply between 2.7 V and 12 V (or split supplies), the ADA4841-1YRZ-R7 draws 1.5 mA quiescent current per amplifier. This makes it a fit for battery-powered instrumentation where the 80 MHz bandwidth is needed but the power budget is tight — the 1.5 mA supply current is lower than many wideband competitors at this speed. The rail-to-rail output stage swings within 50 mV of each rail at light loads, preserving dynamic range in low-voltage systems. Output current is rated at 60 mA per channel, enough to drive a 50-ohm back-terminated line or a typical ADC input.
Package and temperature grade — 8-SOIC, -40°C to 125°C
Housed in an 8-lead SOIC (0.154-inch body width, 3.90 mm width per the package/case spec), the ADA4841-1YRZ-R7 uses a standard surface-mount footprint. The supplier device package is 8-SOIC, so the land pattern matches the industry-standard SOIC-8 layout — no special thermal pad or exposed paddle to route. Rated for operation from -40°C to 125°C, the amplifier covers the industrial temperature range. This qualifies it for outdoor telecom, automotive cabin, or factory-floor sensor interfaces where ambient temperature swings are wide.
