High-Voltage, Precision/Low-Noise Op Amps Offer Excellent Combination of Performance and Low-Power Operation

SUNNYVALE, CA-June 3, 2009-Maxim Integrated Products (NASDAQ: MXIM) introduces the MAX9943/MAX9944/MAX9945 family of high-voltage, low-power operational amplifiers. Designed for power- and space-constrained applications, these high-voltage op amps deliver superior precision (MAX9943/MAX9944) and ultra-low noise (MAX9945). The MAX9943/MAX9944 are ideal for sensor signal conditioning, high-performance industrial instrumentation, and loop-powered systems. The MAX9945 is well suited for portable medical and industrial applications that require low-noise analog front-ends.

The MAX9943 (single) and MAX9944 (dual) op amps operate from a wide, 6V to 38V supply and consume 550µA quiescent current per amplifier to minimize power consumption. These highly precise op amps have 100µV (max) input-offset voltage and 0.4µV/°C offset drift. They offer a gain-bandwidth product of 2.4MHz.

The MAX9945 features 15nV/SqrRtHz input-voltage noise density and 1fA/SqrRtHz input-current noise density, making it ideal for noise-sensitive applications. This device operates from a 4.75V to 38V supply and consumes a low 400µA quiescent current. It has a gain-bandwidth product of 3MHz.

This family of high-voltage op amps is specified over the -40°C to +125°C automotive temperature range. The MAX9943/MAX9945 are available in 6-pin TDFN and 8-pin µMAX® packages; the MAX9944 is offered in 8-pin TDFN and SO packages. Prices start at $0.75 for the MAX9943, $1.25 for the MAX9944, and $0.75 for the MAX9945 (all 1000-up, FOB USA).

Maxim Integrated Products is a publicly traded company that designs, manufactures, and sells high-performance semiconductor products. The Company reported revenue in excess of $2 billion for fiscal 2008. Maxim was founded over 25 years ago with the mission to deliver innovative analog and mixed-signal engineering solutions that add value to its customers' products. To date, it has developed over 6000 products serving the industrial, communications, consumer, and computing markets. For more information, go to www.maxim-ic.com.
