| LSK389 SERIES DELIVERS FUNCTIONAL REPLACEMENT OF TOSHIBA'S 2SK389 |
| |
FREMONT, Calif. - January 12, 2006 - Linear Integrated Systems, a leading full-service manufacturer of specialty linear semiconductors, announces the immediate availability of its LSK389 series of 1nV N-Channel Monolithic Dual JFETs. A monolithic dual version of the recently released LSK170 Single N-Channel JFET. this family of ultra low noise dual JFETs was specifically designed to provide users a better performing, less time consuming, and cheaper solution for obtaining tighter IDSS matching, and better thermal tracking, than matching individual JFETs. Available packaged in surface mount, ROHS compliant versions, the LSK389 is an ideal improved functional replacement for the through-hole Toshiba 2SK389, within space limited circuits for audio and instrumentation applications.
The LSK389's features incorporates three grades of IDSS: 2.6-6.5mA, 6.0-12mA, 10-20mA, with an IDSS match of 10%, a gate threshold offset of 20mV, a voltage noise (en) of 1nv/hz @ 1khz, 2nv/hz @ 10hz typical, with a Gain of 22ms, and 22pf of capacitance.
Great for maximizing battery operated applications by providing a wide output swing, and a high signal to noise ratio as a result of the LSK389's tightly matched gate threshold voltages and low gate threshold voltages. The uniquely linear VGS transfer function is highly desirable for producing low intermodulation in audio front-ends. The 40 volt breakdown provides maximum linear headroom in high transient program content amplifiers. The LSK389 provides a low input noise to capacitance product that has nearly zero popcorn noise. The narrow ranges of the IDSS electrical grades combined with the superior matching performance of the LSK389's monolithic dual construction promote ease of device tolerancing in low voltage applications, as compared to matching single jfets. Additionally, LIS offers custom screening for users who require different ranges of IDSS, VGS or other DC parameters than found in the datasheet.
Packaged in surface mount SOIC-8 and thru-hole TO-71 packages. Lead-Free, ROHS compliant versions are available.
Now a Domestic Source for Low Noise JFETs
"Our new LSK389 series features a unique design construction of interleaving both JFETs on the same piece of silicon that provides excellent matching and thermal tracking, as well a low noise profile having nearly zero popcorn noise," says Dr. John Hall, Linear Integrated Systems founder and president.
Linear Integrated Systems domestic in-factory stock guarantees short lead times, ensuring no disruption in production schedules.
Summary of Features:
- Low Noise (en <1 nv/hz @ 1khz, 2 nv/hz @ 10hz typ)
- Nearly Zero Popcorn Noise
- Availability in narrow IDSS grades/ranges (2.6-6mA, 6.0=12mA and 10-20mA)

LSK170 SERIES DELIVERS DIRECT PIN FOR PIN REPLACEMENT OF TOSHIBA'S 2SK170
FREMONT, Calif. – January 25, 2005 – Linear Integrated Systems, a leading full-service manufacturer of specialty linear semiconductors, announces the immediate availability of its LSK170 series of JFETs, optimized to provide low noise at both high and low frequency with a narrow range of IDSS and low capacitance. The LSK170’s low noise to capacitance ratio and narrow range of low value IDSS provide solutions for low noise applications which cannot tolerate high values of capacitance or wide ranges of IDSS.
The LSK170 offers a voltage noise (en) of 1nv/hz @ 1khz, 2nv/hz @ 10hz typical and a High Gain (yfs, 22ms), with only 22pf of capacitance (Ciss). This series has three grades of IDSS range: 2.6-6mA, 6.0-12mA, and 10-20mA.
The narrow ranges of IDSS binning with the LSK170 promote ease of design tolerancing, particularly in low voltage applications. The LSK170 is ideal for portable battery operated applications, and features high BVDSS for maximum linear headroom in high transient program content amplifiers. The series has a uniquely linear VGS transfer function for a stability that is highly desirable, particularly for audio front-end preamplifiers.
The device is available in surface mount SOT-23 and thru-hole TO-92 packages. The surface mount version of the LSK170 series creates new opportunities for engineers seeking to design lower noise circuits in compact embeddable applications where shielding and space is critical and are not supported with the traditional TO-92 package. The LSK170 series is a pin for pin replacement of the Toshiba 2SK170 and improved functional replacement for the Interfet IF1320, IF1330, IF1331, and IF4500.
Superior Performance, Domestic Source
The LSK170 is specifically designed for low noise, high input impedance applications within the audio, instrumentation, medical and sensors markets.
"Our new LSK170 series feature a unique low noise profile having nearly zero popcorn noise," says Dr. John Hall, Linear Integrated Systems founder and president. "Utilizing large scale integrated circuit technology to build the LSK170 series allows LIS to achieve the goals of high transconductance, low noise and a low value of gate to drain capacitance. This combined with recent developments in Ion Implant technology optimized for low noise has allowed the creation of this state-of-the-art product."
Linear Integrated Systems domestic in-factory stock guarantees short lead times, ensuring no disruption in production schedules.
