Package and thermal integration — 10-HMSOP exposed pad
The ISL1571IUEZ comes in a 10-VFSOP / 10-MSOP (3.00 mm width) package with an exposed pad, designated as 10-HMSOP. The exposed paddle is the primary thermal path — the PCB land pattern must include a thermal via array under the pad to pull heat into the ground plane, or the 1 A output per channel will drive the junction above the -40°C to 85°C operating range under sustained load. Supplied in tube, surface-mount only. The 0.118-inch body width means the pad pitch is tight — a four-layer board with a dedicated ground plane under the pad is the safe starting point for thermal management.
1200 V/µs slew rate — what it buys you
A 1200 V/µs slew rate into a differential output structure means this part can swing a 10 Vpp signal in under 10 ns. That is fast enough to drive the input stage of a high-speed ADC or a cable driver without the output slewing limiting the settling time — the 250 MHz -3 dB bandwidth is real, not slew-rate limited, for signals up to a few volts peak. The 7 µA input bias current and 40 mV input offset voltage are relaxed compared to precision op-amps — this is a speed-first part. The offset matters if you are DC-coupled into a 12-bit ADC; plan for a digital calibration step or an AC-coupled front end.
Supply rails and output drive — 4.5 V to 12 V span, 1 A per channel
The supply span runs from 4.5 V minimum to 12 V maximum. At 4.5 V the output swing into a 1 A load will be limited — check the output voltage swing vs load curves in the datasheet. The 15 mA per-channel quiescent current (30 mA total for both amplifiers) is the standing current before any load is applied; the 1 A output current comes from the supply rails, not the bias. Differential output means the load connects across the two outputs, not from one output to ground. This doubles the available voltage swing for a given supply rail and rejects common-mode noise picked up on the output traces — useful when driving a twisted-pair cable or a transformer-coupled line.
Active production — no obsolescence watch needed
The ISL1571IUEZ carries an active lifecycle status with RoHS3 compliance. Sourced through authorized and independent distribution channels; pricing and lead time confirmed at RFQ against your BOM quantity.
