Product details

Quad CMOS op-amp for general-purpose signal chains

The AD8544ARUZ-REEL from Analog Devices is a quad, general-purpose CMOS operational amplifier in a 14-lead TSSOP package. It delivers a gain bandwidth product of 1 MHz and a slew rate of 0.92 V/µs, with rail-to-rail output swing that lets it run on a single 2.7 V to 5.5 V supply without losing headroom. Each of the four amplifiers draws 45 µA of supply current, making this a low-power choice for multi-channel signal conditioning in battery-operated or thermally constrained boards. The input bias current is 4 pA, so it can interface directly with high-impedance sources like photodiode sensors or pH probes without loading the signal. The -40°C to 125°C operating temperature range qualifies it for industrial, automotive cabin, and outdoor telecom environments.

What the key ratings mean for your BOM

The 1 MHz gain bandwidth and 0.92 V/µs slew rate set the usable signal frequency. The 45 µA per-channel supply current is the headline number for power budgeting.

Frequently asked questions

What is the difference between AD8544ARUZ-REEL and AD8544ARUZ?

The AD8544ARUZ-REEL and AD8544ARUZ are the same silicon in the same TSSOP-14 package. The -REEL suffix denotes Tape & Reel packaging for automated assembly; AD8544ARUZ typically ships in tubes or trays. Electrically they are identical.

What is the equivalent or replacement for AD8544ARUZ-REEL?

The AD8544ARZ-REEL7 is a functional equivalent with the same quad op-amp core and ratings, but in an SOIC-14 package instead of TSSOP-14. For a zero-drift alternative with lower offset, consider the AD8572 (dual) or AD8571 (single), though these are not pin-compatible.

What is the typical application of AD8544ARUZ-REEL?

Typical applications include multi-channel sensor signal conditioning (photodiode, thermocouple, strain gauge), active filters, ADC driver stages, and portable instrumentation where low quiescent current and rail-to-rail output are needed.
