Intersil Corporation has released a 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 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, 6 x 9.9mm QSOP solution is actually smaller than most competitive two-channel devices currently available.
