Intersil unveils first member of its 40V JFET-input precision op amps

Intersil has launched the first member of its new JFET-input operational amplifiers for industrial, medical and sensor markets. The ISL28210 is reported to be a good design choice for process control analog I/O, gas or fluid flow sensors, biometric high-impedance buffers for medical instrumentation. It is also suggested for industrial applications requiring high voltage signal conditioning such as data acquisition, ATE, and power distribution systems. The ISL28210 is an industrial temperature grade, 40V Precision JFET-input op amp.

The ISL28210 operates in a wide 9V to 40V voltage range. This op amp features innovative bias current cancellation techniques that deliver optimal performance at 300 Femto-Amps. The IS28210's input offset is just 300microV, with typical offset drift of 1 microV/°C. The device has a voltage noise of 580nVpp between 0.1Hz to 10Hz and input bias current is typically 300fA at 25°C and an low 4.5pA maximum at 60°C, making the device suitable for instrumentation amps, charge amps and photodiode amps for emerging medical and laboratory instrumentation. The ISL28210 also delivers a slew rate of 20V/microsecond with fast 900ns settling time resulting in good transient performance for ATE and data acquisition analog frontends.

Designed on Intersil's proprietary precision silicon-on-insulator (SOI) bipolar process technology, the ISL28210 exhibits latch-up immunity and high ESD ratings of HBM 4keV and machine model 400V.
