Advanced Linear Devices Inc. added two quad voltage comparators to its precision monolithic high performance line that are said to provide a 0.24A output drive.

The input voltage range on the ALD4301 and ALD4303 comparators, which were built using advanced silicon gate CMOS technology, includes ground or the negative supply rail, making these devices suited for low level signal detection with high source impedance.

Both the ALD4301 and the ALD4303 comparators feature input bias current of 0.1pA, and micropower operation and single (5V) or dual (5V) power supply operation.

The ALD4301 comparator provides 87.5?A supply current per comparator, while the ALD4303 offers 22.5?A supply current per comparator. Both voltage comparators tout open drain outputs that can exceed supply voltage. Each comparator output is capable of sinking up to 60mA. The ALD4301 and ALD4303 voltage comparators have response times of 300ns and 5?s, respectively.

The comparators are intended for a wide range of voltage comparator applications, including PCMCIA instruments, photo detector sensors and battery-operated instruments, and are specifically designed for micropower detection circuits requiring low input currents, high output currents and low standby power.

The ALD4301 and ALD4303 voltage comparators are available in 14-pin CERDIP, SOIC and plastic DIP packages. Pricing starts at $2.28 in 100-piece quantities.
