Industrial-grade comparators and op-amps

6 August 2014 Analogue, Mixed Signal, LSI

Diodes Incorporated has introduced the industry standard LM2901 quad and LM2903 dual comparators, and LM2902 quad and LM2904 dual op-amps in an extended temperature rating. Characterised for operation from -40°C to +125°C, the parts will suit industrial system design in motion control and process automation applications. With an input common-mode range that includes 0 V, the devices operate from a single power supply over a wide voltage range; comparators from 2 V to 36 V and op-amps from 3 V to 36 V. Split supplies can also be employed with the parts: ±1 V to ±18 V for the comparators; ±1,5 V to ±18 V for the op-amps.

A very low power supply current consumption is assured by the parts, which is independent of the supply voltage range. The LM2903 dual comparator, for example, draws only 0,6 mA and the LM2904 dual op-amp just 0,5 mA. Input offset voltage of all parts is also low, at 2 mV typical.

The dual devices are offered in the SO-8 package, while for added design flexibility the quad devices are provided in a choice of SO-14 and TSSOP-14 packages. Package pin-outs are industry standard, ensuring pin-to-pin compatibility with alternative industrial-grade parts.
