Intersil Corporation announced the release of a new family of rail-to-rail input/output instrumentation amplifiers that includes the ISL28470, the industry’s first quad instrumentation amplifier. This one-of-a-kind device features the industry’s lowest offset voltage, best CMRR performance and rail-to-rail input and output capability.
The ISL28470 instrumentation amplifier, part of Intersil’s new pinPOINT™ precision analog product line, delivers exceptional accuracy with an industry-leading maximum offset voltage of +/-150 microvolts and typical CMMR (common mode rejection ratio) of 110 dB. The device is optimized for low 2.4V to 5V single supplies and is capable of swinging above the positive supply rail and to 10mV below the negative supply.
As the industry’s first quad instrumentation amplifier, the ISL28470 simplifies designs and reduces costs for applications that require precise and simultaneous monitoring of multiple variables. This quad functionality eliminates the need for multiple duals or single in-amps for most instrumentation cards. Board space savings are further realized by the fact that this single-chip, 6mm x 9.9mm QSOP solution is actually smaller than most competitive two-channel devices currently available.
For applications that don’t benefit from quad functionality, this new family of rail-to-rail instrumentation amplifiers also includes single and dual versions that feature exceptional signal to dynamic range and voltage offset performance. The single-channel offerings include the EL8170, EL8171, EL8172, and EL8173. The two-channel versions include the ISL28270, ISL28271, ISL28272, and ISL28273.
