Intersil's 5V Zero Drift Rail-to-Rail Precision Op Amp Features Low Power Consumption with Half the Noise

Intersil Corporation (NASDAQ Global Select: ISIL) 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. 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
