STMicroelectronics Introduces LMV331, New Miniaturized Industry-Standard Comparators for Portable Applications

By pur, in Embedded Device, IC, Chip, SoC, Industrial

The LMV331 is a single and low voltage version of industry standard LM339 and LM393. It can operate with a supply voltage ranging from 2.7 to 5 V, and exhibits a lower current consumption than its predecessors LM339 and LM393. This device is a perfect choice for low-voltage applications. The device is available in both SOT23-5 (2.90 x 1.60mm) and SC70-5 (2.00 x 1.25mm) packages, making it ideal for applications where space saving is a constraint. The SC70-5 package is approximately half the size of the SOT23-5. ST’s new LMV331 variants, in miniature 5-pin packages, maximize choice for designers seeking the best combination of speed and power for space-constrained applications…

STMicroelectronics (NYSE: STM), a leading supplier of analog ICs and the market leader in comparators, has completed its portfolio of industry-standard comparators in space-saving packages by introducing the LMV331 in a choice of 2.00 x 1.25mm SC70 or 2.90 x 1.60mm SOT23 form factors.

Battery-powered devices such as notebook PCs, PDAs and other handheld mobile communications products are major users of low-power comparators, such as the LMV331, for duties including signal handling or event detection. ST’s variety of industry-standard comparators enables designers to optimize power consumption, response time and package size according to application requirements. ST’s new LMV331 variants, in miniature 5-pin packages, maximize choice for designers seeking the best combination of speed and power for space-constrained applications.

Performance highlights of the LMV331 include:

Supply voltage range: 2.7V to 5V
Current consumption (Operating): 20µA (Vcc = 2.7V)
Propagation delay: 200ns
Input-offset voltage: 1mV
Input-offset current: 1nA
Operating temperature range: -40°C to +85°C
ESD tolerance: 2kV HBM / 200V MM

The LMV331 is in mass production now, and is priced from $0.25 in quantities of 1000 units.
