High-Voltage Precision Op Amp from Intersil
September 9, 2009
The ISL28127 from Intersil Corp., Milpitas, CA, is a 40 V, low-noise bipolar precision op amp that offers 3.0 nV/rt.Hz at 10 Hz noise performance and 70µV max. offset voltage. Max. input bias current is 10 nA, offset voltage drift is 0.5 µV/°C, and gain bandwidth is 10 MHz. The op amp is unity-gain stable over the –40°C to 125°C temperature range and operates from a 4.5–40 V supply voltage. Applications include laboratory instrumentation, automated test equipment, power line monitors, weight measurement systems, and environmental analyzers that require low DC noise. The op amp's low distortion and gain accuracy suit it for use in low-noise preamps, loop filters, strain gauge sensors, and precision power sources.
