AD8019ARUZ

Overview

The AD8019ARUZ is a dual high-speed operational amplifier manufactured by Analog Devices Inc. in the TSSOP-14 package. It features a gain-bandwidth product of 230 MHz and a slew rate of 150 V/us. The device operates on a single supply voltage ranging from 5 V to 10 V, with a typical supply current of 16 mA per channel. Input offset voltage is typically 2 mV, and input bias current is 15 uA. Output current capability reaches 75 mA per channel, supporting rail-to-rail output swing.

Feature Summary

• High-speed performance with 230 MHz gain-bandwidth product
• Fast transient response with 150 V/us slew rate
• Rail-to-rail output capability for maximum dynamic range
• Low power consumption relative to speed class

Applications

• Video signal processing and buffering
• High-speed data acquisition systems
• Broadband communication interfaces
• Test and measurement instrumentation

Procurement Notes

Verify the specific suffix ARUZ corresponds to the TSSOP-14 surface-mount package when sourcing. Confirm that the operating voltage range aligns with system requirements, as performance characteristics may vary with supply voltage changes. Ensure thermal management considerations are addressed for the TSSOP-14 form factor under continuous load conditions.

Selection Notes

Select this component for applications requiring high bandwidth and fast settling times in a dual-channel configuration. Compare against the AD8018 if higher output current or different noise specifications are required. Consider the AD8040 series for quad-channel implementations with similar speed profiles. Validate input common-mode range compatibility with the signal source.

Part Context

The AD8019 belongs to Analog Devices' family of high-speed bipolar operational amplifiers designed for demanding analog signal chain applications. It complements other devices like the AD8018 and AD8040 within the portfolio, offering a balance of speed and power efficiency. The ARUZ designation indicates a specific lead-free, halogen-free TSSOP-14 package variant compliant with modern environmental standards.

Replacement Considerations

Direct pin-compatible replacements include the AD8018 for higher current drive or the AD8040 for quad-channel integration. Verify that substitute devices meet the same 230 MHz bandwidth and 150 V/us slew rate requirements. Check for differences in input offset voltage and noise density if precision is critical.
