Intersil Corporation has extended its family of precision op amps, introducing a new 5V, ultra-low noise, chopper-stabilized zero drift rail-to-rail amplifier featuring half the noise of competitive amps that consume similar power. The ISL28134 is an excellent design choice for amplifying small signals in analog front ends that interface to pressure, temperature, medical, strain gage and inertial sensors. It is also ideal for low noise instrumentation systems by providing amplification before 24-bit delta sigma ADCs
Excellent Design Choice for Amplifying Sensor Signals; Ideal for Low Noise, High End Instrumentation Systems

Features and Specifications

Noise voltage from 0.1Hz to 10Hz is only 0.25microVpp
Ultra-low offset voltage of 2.5microV max and drift of 15nV/degree C max
Operating current consumption of only 675microA
Rail-to-rail input/output capability maximizes signal levels
CMRR of 135dB minimizes errors in differential input configurations
