NEW LM393B and LM2903B

Improved specifications of B-version

– Maximum rating: up to 38 V

The LM393B and LM2903B devices are the next

generation versions of the industry-standard LM393

and LM2903 comparator family. These next

generation

B-version

comparators

provide

– ESD rating (HBM): 2k V

outstanding value for cost-sensitive applications

featuring lower offset voltage, higher supply voltage

capability, lower supply current, lower input bias

current, lower propagation delay, and improved 2 kV

ESD performance and input ruggedness through

dedicated ESD clamps. The LM393B and LM2903B

can drop-in replace the LM293, LM393 and LM2903,

for both "A" and "V" grades.

– Low input offset: 0.37 mV

– Low input bias current: 3.5 nA

– Low supply-current: 200 µA per comparator

– Faster response time of 1 µsec

– Extended temperature range for LM393B

– Available in tiny 2 x 2mm WSON package

B-version is drop-in replacement for LM293,

LM393 and LM2903, A and V versions

Common-mode input voltage range includes

ground

•

All devices consist of two independent voltage

comparators that are designed to operate from a

single power supply over a wide range of voltages.

Quiescent current is independent of the supply

voltage, and the outputs can be connected to other

open-collector outputs to achieve wired-AND

relationships.

Differential input voltage range equal to maximum-

rated supply voltage: ±38 V

Low output saturation voltage

•

Output compatible with TTL, MOS, and CMOS
